The Goal of Voyager Ocean Passages
There comes a time in many sailors' lives when they realize they want to expand their horizons and sail offshore, taking extended cruises or visiting foreign lands. Voyager Ocean Passages supports those dreams with a comprehensive training program that teaches the skills and methods of offshore sailing during actual ocean passages on a modern, well equipped ocean sailing yacht. The knowledge gained and first hand experience allows sailors to become confident and competent, able to sail anywhere they wish. We are more than an offshore sailing school; more like a university!

Excerpt from the course

So far, we’ve hoisted the jib, adjusted halyard tension, and trimmed the sheet so that telltales at the bottom and middle sections stream back well. Now it’s time to compare telltales from bottom to top. Inequalities are corrected by adjusting the jib fairlead position.

jib too far open

Figure 3a: The jib fairlead is positioned too far aft, opening the upper leech and spilling air out. The upper telltale flutters forward because wind is choked off from that part of the sail. This is corrected by moving the fairlead forward

Figure 3a illustrates a sail with its lead too far aft, with the upper sail presented to the wind at too broad an angle. Insufficient airflow and turbulence causes the upper windward (red) jib telltale to dance forward while the middle and lowers stream back nicely. The leech is allowed to open up and air spills out of the sail aloft. The loss of air pressure decreases left and drive, slowing the boat down.
