Students consistently call this a comprehensive, no-fluff course that’s “very complete,” well-structured, and packed with clear explanations, diagrams, and helpful videos/VR—often described as tougher (in a good way) and more in-depth than other programs they’ve taken. Many use it as a serious refresher after years on the water and report a measurable confidence boost, especially when tying together rules, systems, navigation, docking, and emergency decision-making. Reviewers praise the practical focus, the “why behind the what,” and the way testing feedback cements understanding. The consensus: it’s demanding, engaging, and exceptionally well presented—worth taking early in your journey or when stepping up to larger keelboats, with lifetime access making it a valuable reference long after completion.
Why Take the Skipper Large Sailboat (Keelboat) Course?
Sailing a large 26-56 ft sailboat opens an entirely new level of sailing adventures. While many sailing skills and principles are universal, sailing larger sailboats (i.e., “keelboats”) requires additional knowledge and skills to handle the increased power, speed, and weight, as well as the myriad of helm, engine, and system options.
The reward is sailing faster, further, and in diverse weather conditions. In many ways, being on the water on a large sailboat is the ultimate freedom! You’re only limited by how well you develop the knowledge and skills to handle a large boat. This course is designed to give you the confidence and know-how to sail and manage a 26-56 ft keelboat, letting you enjoy the freedom, safety, and excitement that come with big-boat sailing.
This course is also a cornerstone of practical training with a qualified NauticEd instructor as well as a requirement for bareboat chartering certification and licensing, and a precursor for Catamaran training.
This Course is Perfect for You If:
You're a beginner or intermediate sailor who wants to skipper large keelboats and coastal cruising.
You’ve sailed before but want a modern, no-fluff online sailing course to refresh and advance your skills.
You’re planning a bareboat charter and want to begin pursuing bareboat charter certifications and licensing.
You’re an owner who wants confidence with electrical and diesel systems, not just sail and boat handling.
Your enrollment includes lifetime course access, recognition on your free NauticEd sailing resume, and a complete satisfaction guarantee.

Previously trained in ASA, and I found the perspectives here to be quite complementary to that content and well worth spending the time reading. I thought I might just test out of each section, and instead found myself enjoying the reading, examples, videos and dynamic illustrations. Well done content, with good insights on leadership too. I will continue with this program of learning.

I loved the course and that I could take it at my own pace and re-do each segment multiple times (over weeks & months) which I felt really helped me understand it better. Thank you!

This is a good comprehensive course. If you've done an ASA106 or US Sailing Coastal Passage Making, this will be mostly review. If you've done ASA104 or US Sailing Bareboat, there are still a few things to be learned here.

The course was very detailed. I really felt I learned it lot. (I have taken several ASA courses, including Coastal Navigation, but this was much more demanding..which is good!
The following illustration shows the parts of the sail and associated control lines. Of note is the bolt rope which is one of the few actual ropes on a boat (another is the bell rope).
The bolt rope provides strength to the luff of the sail and is used also to slide into the track if there is one. On a head sail the bolt rope provides strength to the luff of the sail when "hanks" are used.
Hanks are basically sliding clamps that slide up the forestay and are clamped onto the bolt rope at the leading edge (luff).
The main halyard is attached to the head of the sail and is used to pull the sail up the mast.
The gooseneck is a swivel connection from the boom to the mast.
The reefing points are points where the sail can be pulled down in order to reef the sail if a roller furling system is not used.
The topping lift holds the back of the boom up.
The boom vang holds the boom down when beating to the wind. On downwind legs, the boom vang can be loosened to provide more shape to the sail.
The Cunningham pulls the sail down tight and is also used when reefing.
The outhaul line is attached to the clew to pull the sail out along the boom.

Module 5 Rules and Safety- Excerpt:
In the video below, you can see two sailboats on a collision course. The sailboat on a port tack correctly changes course to avoid the sailboat on a starboard tack. The port tack boat also could have turned to starboard to duck in behind the other boat. However, in this case, it chose to tack. The decision to tack or duck is up to you.
Module 6 Slip Departures and Returns - Excerpt:
(3) Wind pushing into the dock and current from behind.
This is a little more tricky. If you try to go out forward the wind could potentially push you into other boats. Additionally, as you turn the wheel to head out, the rear of the boat will swing around towards the dock and other boats. therefore it is recommended that you reverse out using a spring line.
(A) Once you are confident in your plan,
Appoint a crew member to use a fender at the front of the boat to prevent the boat from touching the dock.
Release and stow the dock lines but leave one spring line from the dock near the center of the boat attached to the front of the boat.
The spring line should be arranged so that it is attached to the forward cleat, runs freely around the dock cleat, and returns back to the appointed crew member. In this manner, the crew member can release the line and retrieve it by letting it slip around the dock cleat. ENSURE that there are no knots in the line to get caught on the dock cleat as it runs through.
Turn the wheel towards the dock and engage the forward gear.
This will have the effect of pushing the rear of the boat away from the dock.
(B) Once the boat has turned out from the dock, engage reverse and have your forward crew member release and retrieve the spring line.
(C) Continue backing out to be completely clear before engaging forward gear. Remember the rear of the boat will swing back towards the dock once you engage forward and turn the wheel to windward, so ensure there is plenty of room.
Module 7 Sailing - Excerpt:
Conversely, when you ask the wind to bend too much, the wind will spawn off creating turbulent airflow. This reduces the effect of the sails and slows the boat. The higher the velocity of the wind the less the wind tends to bend. This is one of the reasons why in high wind conditions you need to reduce the size of the sail. Since the sail is smaller when reefed, the wind is required to bend less over the distance from the front (luff) of the sail to the back (leech) of the sail and therefore the wind will not break away from the sail as much. Once the wind breaks away from the low-pressure side, as shown in the diagram below, you're reducing efficiency. In the same way, an airplane will stall. When the flow of air breaks away from the top side of the wing, the lift is lost and the plane quickly aims itself at the ground. In sailing, the result is less dramatic. Simply let the sail out and the wind will reattach to the leeward side of the sail.
Module 9 Anchoring and Mooring- Excerpt:
Care must be given to swing. As the wind changes during the night, your boat will move with the wind and can put you into a precarious situation by being too close to the shore. Many times you'll find an anchorage area with moorings. Remember that boats tied to moorings swing less than anchored boats. In this circumstance, you may swing into other boats. The golden rule is "watch your swing".
In addition, consideration must be given to the tide. As the tide "ebbs" out, you not only get closer to the bottom but your swing circle grows and the shore becomes closer. This diagram shows your swing path with deep water and the correct scope.
Module 10 Emergencies - Excerpt
Deep Beam Reach
Bear away to a broad reach
Trim the main sail for speed, furl, or drop jib.
Tack
Sail a beam reach toward the victim.
Make the final approach to the leeward of the victim.
THE TESTS
Each Module has associated with it approximately 20 test questions. Here is an example?
Q Who has the Ultimate right of way in this scenario?
You will find the answer to this question in Module 5 of the Skipper Course.
Upon passing all the tests associated with each module, your NauticEd Sailing Certificate is automatically updated. This is not a USCG Captain's license. It is an acknowledgement that you have passed the NauticEd Skipper Course which is recognized by charter companies worldwide.
It's impressed me that although my sailing experience spans over 65 years,
I always learn something new when going to your website. This is particularly true
when using NED.
