H240 Waterline
The knowledgebase is at this link: Link submitted by authorThere is not much on the H240 but you'll do just as well looking at the H26 and H260 pages. The centerboard line replacement section is at H260 repairs section.The smaller, lighter the boat the more "tender" the boat. The H240 is less tender than most boats of this size with a displacement of 2300lbs and 1330lbs of ballast. The only objective way I know to look at this subjective term "tender" is to compare the Displacement/length ratio, the Ballast ratio and the Sail/displacement ratio of competing boats. I think you'll find the H240 compares very favorably. Crunch the numbers before deciding the H240 is too "tender".There are a few 24ft boats that are less tender; for example, the Dana 24's displacement is over 8000lbs and most models probably weigh close to 10,000lbs. Try towing that across the country.The smaller the boat, the better sailor you have to be. Learn to deal with wind and waves and you'll grow to love the H240 -- it's an ideal first boat.Two defensive strategies worth learning are: when to reef and how to heave-to. Once you get that down, you'll be able to handle virtually all conditions and have fun doing it. If the water in your ballast tank valve can be touched with a finger that's the waterline. Think about it, water seeks its own level, so as you load the boat the water in the ballast tank valve will rise. Also, look at how high the stern rides. The sugar scoop stern is usually just a few inches above the waterline and when sailing is anally under water. Finally, there is a very light raised waterline mark all around the hull of the boat. You have to use a finger to feel it. This is a guide for the person painting the bottom. As noted, on this boat the "keel" is actually a centerboard and only heavy enough to keep it deployed down - about 60lbs.Pat Adam's pictures and narrative for replacing the centerboard in the H260 knowledgebase are very detailed. Because the H240 and the H260 are virtually identical except for the size there are lots of other tips that apply to your boat in the H260 knowledgebase.
