Easy Rigging a Barber Hauler on Your Boat

A Barber Hauler was invented by the Barber brothers. They wanted to be able to further control the shape of the jibsail and the position of the jibsail clew. On cruising boats, its not sometimes practical to go to all the extra expense of installing all the gear they originally suggested and so various forms of achieving this have been devised and loosely now they are all called Barber Haulers.

We discuss this and many other fine tuning sail trim techniques in our advanced Sail Trim Course.

If you think this is the greatest idea on the planet or at least just a very good one, please like us on facebook.

Posted by Grant Headifen, Global Director of Education – NauticEd.

One of the greatest things I love about my job is the ability to apply the latest technology to the sailing education industry – it is so exciting to be leading the world in this area.

And – today comes as a greatly awaited day for us to announce one of the bigger innovations in not only sailing education but in the entire community of eLearning itself.

I’d like to introduce Nano-Forums!!!!!!!!

Please watch this video and you’ll see why our Sailing Nano-Forum is so innovative and such a benefit to the sailing community at large – You’re Welcome! It represents a MASSIVE investment in technology over the past 6 months. Ummm like really REALLY massive but we think it’s worth it!

We think you will really enjoy it.

Oh and btw since this is new technology to the world and we invented it, we are coining the phrase NANO-FORUM right here right now!

What it ultimately means is that we all now can collectively crowd source information in targeted specific areas and re-use the crowds knowledge for educational drill down topic purposes in a way never been done before.

Just watch the video – you’ll get what we are talking about.

Please engage in the Nano-Forums through out our courses. Look for the SeaTalks button at the top right of every page of the course.

Entering Experience into your sailors logbook

Posted by Director of Education on July 9, 2015 under About NauticEd, Bareboat Charter, Coastal Navigation, Crew, Skipper | Comments are off for this article

Airline pilots, naval seamen, scientists and scuba divers all maintain a logbook. So why don’t sailors? Because it’s just in the too hard bucket with seemingly no point to do it. Until Now! If you ever want to charter, you MUST have a sailing resume. Yacht charter companies DO NOT accept a sailing certification – they will always ask for a resume which requires you to list your experience and theory courses. The NauticEd Logbook is your simple way of storing it in the cloud for all time. Accurate and up to date! AND you can only gain Rank with NauticEd when you list your experience – it’s why every yacht charter company in the world accepts our resume/certification because they both go hand in hand. To gain the Bareboat Charter Master Rank Certification you simply must have listed an acceptable amount of experience which guarantees acceptance by the charter company. i.e. 50  qualifying days on the water with the NauticEd Bareboat Bundle of courses completed is yacht charter company acceptable.


At first thought, you might think that entering all your sailing history is too daunting of a task. But it’s not – we’ve made the interface easy and very quick. The big thing is that your last entry is remembered and so you can literally enter a whole week of sailing in  14 clicks. Additionally, you don’t have to enter all  the information.

Here is how to get 100 entries done in about 20 minutes.

Start with your most recent years first. How many times have you been sailing this year, last year and the year before? Did you go mostly in the summer and some in the fall, spring winter?

Next realistically start to enter an equivalent amount of days that you probably went this year. Pick dates that would be sort of reasonably close. e.g. if you went sailing say 5 times in the first 2 quarters of the year then pick a day in January, 2 in February, 1 in April and 2 in May. Something like that!

You’ll notice that when making a second entry that the last entry you made is queued up all you have to do is change the date slightly. For past entries, you don’t need to add the non asterix stuff – just the date, the vessel and if you were master or crew. In this manner you can do about 6-10 entires per minute. Now go back to last year and repeat – then the year before. Keep going until you have enough entires that realistically reflect your recent 3-4-5 years of experience. This will take about 20 minutes. If you want to go all out, go for it, invest another 20 minutes.

If you have a few 7 day charters then try to remember the month that you did it in and make the first entry then see the second entry already queued up whereby you increment the date by 1. In this manner a 7 day charter takes about 30 seconds to enter.

This 20 minute exercise will bring you up to date.

How to make a logbook entry into your FREE NauticEd Online Sailor’s Logbook

The NauticEd logbook is maintained for you for free in the cloud and is always accessible by you and anyone you specifically designate with permissions. Additionally it is easy to edit and update. You can do this either online or via our iOS NauticEd App. In the App you can make an instant entry when you get off the boat at the end of the day.

Another important feature of an experience logbook is authentication. We created a CrewMate Authentication (TM)  system whereby your logbook entries get reported as authenticated. Read about CrewMate Authentication here. So you want to be setting up CrewMates in your logbook area so that your CrewMates can auto authenticate your entries as you make them (optional but it gives credibility to your logbook).

Finally we are about to launch an exciting new product into our App. It is a gps tracking system that will record and store your daily tracks for you. At the end of the outing the gpx file is uploaded to your logbook and you can see your tracks at anytime in the future. Plus the track stores your miles for you AND this also creates an authenticated entry into your logbook. We expect to Launch this sometime early in 2016.

Mast head light confusion

Posted by Director of Education on April 20, 2015 under About NauticEd, Bareboat Charter, Coastal Navigation, Crew, Rules of Right of Way, Skipper | Comments are off for this article

Here is a question from a Student who posted it on Disqus. I felt it was important enough to post out here for public. Displaying correct lights on boats is important.


Could you please provide more of an explanation for the following:
Although ‘steaming light’ is used extensively, this does not have a definition within the IRPCS [International Regulations for Prevention of Collisions at Sea], the correct definition being a masthead light.

If the tri-colour light can replace the stern and red/green pulpit light on a sailboat how can it be unacceptable to use the tri-colour light with mast head light? If you are under power you of course need your steaming light/ mast head light illuminated. So if you don’t have pulpit or stern lights aboard as you are using a tri colour light how can you do this?


Agreed – lights can be confusing at the onset. In this particular topic, sailors tend to get confused because they think  a mast is only on a sailboat. But, a mast head light is also used (and defined for use) on power boats. Take a look at this image shown in the rules. It shows a power driven vessel longer than 50 meters using two mast head lights.

A large Power vessel displaying two mast head lights.

A large Power vessel displaying two mast head lights.

Here is the definition of a mast head light in the rules:

(a) “Masthead light” means a white light placed over the fore and aft centerline of the vessel showing an unbroken light over an arc of the horizon of 225 degrees and so fixed as to show the light from right ahead to 22.5 degrees abaft the beam on either side of the vessel.

Note also that is does not say the light must be at the top of the mast.

For sailboats, a tricolored light is a light described by rule 25(b) in USCG Nav Rules. It is at or near the top of the mast and is for sailing vessels less than 20 meters in length. It is an optional alternative to having the lights down on the hull or pulpits. It faces a white light to the aft 135 degrees plus red from directly forward around to port 112.5 degrees and a green light directly forward and around to starboard 112.5 degrees. This makes up 360 degrees and meets the requirement for a sailboat sailing. When the sailboat turns on it’s engines it must also in addition to the white, red and green above, display a white light 225 degrees facing forward. You can name this light what ever you like but it must exist. These white “mast head” lights are also defined by the distance they must be seen by – it does not mean they have to be at the top of the mast. On power vessels they are typically at the top of the mast because that is what the mast is for.

Here is a sailing vessel under sail only with a tricolored light


Tri-colored lights on a sailboat

Tri-colored lights on a sailboat


On a sailboat less than 50 meters in length, a mast head light (white under power light) can by just “up the mast” anywhere. It’s not part of the tri color. It is white and faces forward 225 degrees and is to be used when the sailboat is under power. You also might be confusing the term mast head light with the two all around red and green lights at the top of the mast. These are not mast head lights. They can be used in addition to the hull or pulpit mounted red green and white. The rules prevent a top of the mast tricolored light AND the two all around red and green at the top of the mast. This would create confusion and may be your source of confusion. i.e it is unacceptable to use the tricolored and two all around red and green lights. Again the mast head is white 225 deg forward facing to be used under power only.

Here is a vessel with the two all around red and green lights.

The Vessel sailing "on starboard" is utilizing the optional two all around red and green lights.

The Vessel sailing “on starboard” is utilizing the optional two all around red and green lights.

Here are the rules as stated:
Rule 25 – Sailing Vessels Underway and Vessels Under Oars

(a) A sailing vessel underway shall exhibit:

(i) sidelights;
(ii) a stern light

(b) In a sailing vessel of less than 20 meters in length, the lights prescribed in Rule 25(a) may be combined in one lantern carried at or near the top of the mast where it can best be seen. [note this is the tricolored light]

(c) A sailing vessel underway may, in addition to the lights prescribed in Rule 25(a), exhibit at or near the top of the mast, where they can best be seen, two all-round lights in a vertical line, the upper being red and the lower green, but these lights shall not be exhibited in conjunction with the combined lantern permitted by Rule 25(b).

I hope that helps.

I highly recommend that you complete our Navigation Rules Course. It is free for everyone.

This is the continuing NauticEd Staff and friends Thailand Sailing trip with The Moorings on a Catamaran 4600.

Last night we slept anchored up next to the beautiful Rai Leh beach which was an excellent stop.

This morning we set sail (actually motored because there was no wind) south in search of a good snorkeling spot on the way to Ko Phi Phi.

Note that I am taking these chart pics off the Navionics Asia App which we used exclusively through out the trip. We did not use the onboard Chart Plotter. The iPad app is so much friendlier.

First stop was Ko Dam Khwang. On the way is Koh Dam Hok with its unique chicken head rock

We stopped on the north side where other tourists were also snorkeling. Actually compared to our next stop at Ko Mai Phai it wasn’t that great just to be honest. A few of us got nailed by jelly fish and the tide stream was flowing pretty hard so we elected to move on in search of the perfect snorkeling spot.  But we did have some fun in the dinghy. Notice the expert foot steering whilst I held the GoPro.

But just before we left Koh Dam Khwang we went off the back of the boat with a few pieces of bread. Awesome colored fish were everywhere.

Next stop was Ko Mai Phai where the ultimate reward was awaiting us. We anchored in the sand so as not to damage the reef and swam to the reef. The snorkeling was spectacular with Sea Anemones complete with Clown fish and clams, fish

Back on the boat and the wind started to build. Wow – yah finally. Hoist up the John B’s sails (Beach Boys)!

We set sail on a close haul for Ko Phi Phi but we were enjoying the sailing so much we purposefully overshot the island by 5 miles just for fun. We tacked over and did a nice reach onto the southern bay of Ko Phi Phi. We motored right up to the water dock in about the position marked. Water tank fill up was 1500 bhat (kinda expensive $us40) but it was well worth it. The girls were starting to complain (not really).


Ko Phi Phi

Ko Phi Phi is a very alive town with tons of tourists (tons). But with that goes lots of good thai food and lots of night life.

Returning back to the yacht, again we experienced the large tides. We had left the dinghy high and dry on the beach with the fore thought to tie it carefully to the rock wall. When we returned later it was happily floating in 2 feet of water. Thanks to our handy tide app we knew at all times what was happening tide wise.

We had to anchor out quite a way because of all the yachts in the bay. 15 meters would mean a little over 3 scope on the all chain  anchor. I checked our pocketGRIB wind App and saw no wind coming over night so anchoring deep wasn’t a concern and by now we were pretty confident that the Bruce anchor was holding very well in mud.

That’s it for Day 3

Sailing in Thailand – Day 2

Posted by Director of Education on April 2, 2015 under About NauticEd, Bareboat Charter, Coastal Navigation, Crew, Skipper | Comments are off for this article

This is Day 2 of our Sailing trip with the Moorings in Thailand.

What a great evening that was last night – anchored up completely remotely next to Ko Ku Du Yai with the delicious dinner of shrimp from the local fishermen. Here are our crew boys peeling the shrimp.

Day 2 Itinerary

Sailing in Thailand -Day 2 Itinerary


In the morning, we headed south weaving through the spectacular islands.

Spectacular Islands of Thailand

Spectacular Islands of Thailand

First stop was Ko Phak Bia for a snorkelling stop and where I snapped this great shot of a typical longtail boat used extensively by the Thai for fishing, lugging tourists and anything on the water. The boat has a car engine mounted on a balance with a direct-drive long (long) drive shaft coming out the back. You can see the saltwater cooling lines out the back into the water. To steer, the driver pushes down on his balance handle lifting the spinning proper out of the water, he then swivels the entire engine and drive shaft and places the proper back in the water. The sight of a spinning proper waving through the air makes you want to stay very clear away. This type of boat is used extensively throughout Asia. The efficiency lies in the ease of maintenance. Car engines are relatively cheap and easy to mount. I imagine the Mercury dealership has a difficult time penetrating the market.

Thai Long Tail boat

Then further south down to the very impressive (2nd) Ko Hong. At high to mid tide, this hong is filled with water and you can dinghy in and have a delightful swim inside the impressive hong approximately 300 m in diameter. We had to anchor outside the hong in fairly deep 20 meters of water with a falling tide. The boat had 50 meters of chain so we let it all out. The winds were extremely light and so I felt safe with a 3 to 1 scope. Would have preferred 4 to 1 with all chain.

Three of the female crew abandoned us and headed off on the kayak into the hong.

Then we headed off in the dinghy. This is the entrance.

We moved on to the famous Rai Leh Beach which is renown strangely enough for rock climbing. But also the Thai version of  food trucks. Below, all the boats park up on the beach and serve up delicious Thai food albeit, I did notice a few hamburgers scattered in the menus. A pleasant walk from the beach cuts you past the peninsula headland taking you the other side to a long row of very nice resorts and restaurants. This place is a good stop.

 We anchored in 2 meters of water at low tide being careful to let out enough chain to accommodate the 5 meters of depth sometime in the night. The cliff behind our anchoring point was incredibly impressive with 10meter long stalactites.

How to Calculate Course To Steer (CTS)

Posted by Director of Education on April 1, 2015 under Bareboat Charter, Coastal Navigation, Crew, Skipper | Comments are off for this article

If you like our problems and solutions, LIKE us on facebook and g+1 us. It really helps us grow – thanks for that. AND you’ll get instant notification when we make a new problem or post a solution. How cool is that?

Course to Steer Calculation

Given the last Rate and Direction problem, now calculate the CTS (Course to Steer) to go to the safe water mark RW “NH” and the TTD (Time to Destionation)?

Answer is posted below. BUT please give it a go first to test your current knowledge.and post your answer to our



Here is the Answer plot (no cheating – give it a go first) (no really) (oh come on really – give it a go first)


CTS and TTD plot

CTS and TTD plot

In this answer plot we used 1/2 hour for the time frame. Thus with current flowing at 1.8 knots in 1/2 hour the distance the current will push you off course is 0.9 nm at 17 deg T. Your speed is 5 knots through the water so in 1/2 hour you would travel 2.5 nm.

In the answer plot I have done it two ways. Both work equally as well. First I drew the desired track from the eFix through the buoy RW “NH”. The first vector I plotted was from the eFix to Point A using the current vector (0.9 nm at 17 deg T). Then from Point A, I scribed a 2.5 nm arc to cross the desired track. This gives me position C. I drew a line from Point A to Point C. This gives me what is called a water track. Designated by 1 arrow (mnemonic “water has one”). I measured this direction which is 118 deg T. This is the CTS (Course to Steer). It means if your boat heading is 118 T then your ground track will be from the eFix position towards point C AND towards the Buoy RW “NH” since it lies on the same line.

The distance from the eFix Position to Point C is 2.5 nm. Since you will travel at 5 knots this will take you 30 minutes. NOTE: it is just by pure coincidence that this is the same speed as the boat through the water in this case. i.e. the way you find the boat speed over ground is to measure the distance from the eFix to point C and divide by the time. In this case it just so happened that the distance from eFix to Point C is the same distance as Point A to Point C. You can imagine it would be totally different if the current direction was 30 deg T instead of 17 deg T.

NOTE: also I have solved the problem using the vectors in a different manner. First I scribed an arc 2.5 nm out from the eFix Position. Then I brought in the current vector so that the end was touching the desired track line and moved it until the start touched the scribed arc. This result satisfies the condition that the boat must move 2.5 nm whilst the current brings the boat back to the desired track. The start of the current vector creates Point B. Then I drew a line from eFix to B to create the water track. The water track is the heading of the boat. The heading is (and must be) exactly the same as before at 118 deg T.

This second method, just to me,  seems to make more sense of a vector triangle because I can see the boat starting from the eFix and heading out at 118 and getting dragged back to the desired track line. Maybe it’s just me. In any case the triangles are exactly the same. I believe however, that using the first triangle method may be more accurate in real live plotting because you draw the lines from exact points. In the second method, you’re moving that current line to satisfy the two conditions. My brain however, thinks the first method looks weird. i.e. the current drags you all the way out and you have to crawl back. In either case this is not reality. In reality, your boat just follows the desired track. If your mind can handle the first method do it that way.

Next part of the problem is to calculate TTD –  the time it takes to get to the buoy.

That’s easy – the distance is 3.2 nm. At 5 knots this will take 0.64 hours = 38.4 minutes.

Now could you solve this problem if the was ALSO 10 degrees of leeway with the wind out of the North?

If you need help, consider taking our Coastal Navigation online class or our iPad eBook App Coastal Navigation course these types of problems and solutions are taught throughout the course.

Permission for a rant? (if you know me, I break out in rants every now and then. It’s a collection of thoughts and I tell you its a rant so as not to offend – ie don’t read this if you’re sensitive)


This problem should be second nature to you. In reality, you’re probably not solving these problems everyday whilst sailing and it’s why some people think they can get away without knowing this stuff. However, this is fundamental to sailing and I think it is irresponsible (strong word – I said it was a rant) to not be able to lay out the method to solve this problem. Laying out the method means you grasp the concept which is the most important to understanding and keeping you out of trouble.

Example: Last year whilst sailing from St. Lucia south to St. Vincent we saw a sailboat way to the west almost on the horizon about half way across. He had left St Lucia and held a compass heading towards St. Vincent. In the meantime, we calculated a CTS and sailed in a straight line over ground to St. Vincent. His path was a complete arc which took him miles off course. Our path was the shortest distance between two points ( a straight line). I’d call this guy a crappy sailor – I know this because of another rant that I wrote about the same guy when it comes to a crossing and give way situation later on as we approached our bay on St. Vincent [see that blog article and story].

Don’t be a crappy sailor – sail with knowledge. It might seem like a selfish rant to get you to buy more courses – maybe or maybe it is and an attempt to reduce the number of crappy sailors out there. NauticEd courses are ridiculously amazing value and after taking at least our Bareboat Charter Master Bundle of courses, I guarantee you will not be on Neptune’s naughty list.

Personally, I’m impressed with the European community and requiring the ICC for all sailors. The ICC requires the above type knowledge. When you’re sailing in Croatia, Greece, France etc, on a Bareboat Charter, you’re nervous enough. You don’t want all the other charter skippers having limited sailing knowledge. If you know they all have the ICC, you’re going to be a lot more comfortable in a crossing situation.

NauticEd has taken it a step further by not only providing the ICC but offering the Bareboat Charter Master bundle of courses. These courses really ready you for a proper safe Bareboat Chartering Experience.
