Position the boat in the middle of the line facing directly in to the wind. If the line is biased, the boat will be pointing more for the favored end of the line, than the wrong end. In recent months BYC has rescued many Hobbies encountering problems after the capsize. It appears that problems are exaggerated as many boats are leaking in one or both hulls and often the mast is not watertight. If the mast fills with water it is virtually impossible to right a turtle'd Hobbies.
Problems stem from the age of many of the boats, and the harsh environment in which they are kept.
The hobbies should be regularly leak tested by forcing air through the bunghole. Soapy water is then passed over suspect areas and any leaks will be obvious from the bubbles. As Hobbies have a relatively low volume they will be dramatically affected by only a small amount of water. Particularly during tacks water will rush to the back of the boat causing the bow to lift and wind to blow under the trampoline forcing the boat over backwards. Common areas where Hobbies leak are along the gunwales, at the join between deck and hull and at the points where the trampoline bars are attached.
