    Improve old boat or upgrade?

    Thanks for the encouragement. So far I am happy with progress but I need more data to confirm the performance improvements meet my predictions. What I lack right now is a good data tracker APP to analyze speed, direction, etc. Any suggestions?

    Improve old boat or upgrade?

    It leaks, a lot! I work with fiberglass for other reasons so this is not a major challenge, I hope.

    Improve old boat or upgrade?

    A few years back I needed a trailer for the 'Tuffy' motor boat I built from Glen-L plans. I found one for $150 and it came with a ragged old Sunfish, with the old rudder mount and no dagger board or rudder. The Sunfish is now on the water more than the Tuffy, it is so much fun. Since I got...

    Sunfish Sail: Leech Cupping issue

    Just like an early Ford, available in any color of your choice, as long as it is black.

    Sunfish Sail: Leech Cupping issue

    Thank you for the good replies. My old SF came with an older silk-like sail with no cupped leech/leach. And it was stable, but looked more like a quilt than a sail with numerous patches. The overall quality of my new bargain SFD sail is good, but I do not have the experience to judge it...

    Sunfish Sail: Leech Cupping issue

    I have been sailing this year with a new 'Sunfish Sail, White, 10016' from Sunfish Direct. The quality is good but the leech has a permanent cup/hook to it that I have not been able to eliminate through rigging and re-rigging. If I think of the cross-sectional airfoil this creates it is akin...

    My improved dagger board and rudder

    Thanks. Sounds like a terrific community of people, similar to my flying buddies, many who have ‘Gone West’ as we say.

    Thanks for the great comments! Forums like this are a terrific means to gain ideas, even when one question sometimes generates conflicting opinions.

    My improved dagger board and rudder

    The ISCA people I have corresponded with are not considering new rudders or boards. My interest is to seek an experienced competitor in my area to comment on my parts and try them out when not competitive. I will not live long enough to gain their expertise.

    My improved dagger board and rudder

    Yes, I am in touch with leaders in the US ISCA organization and appreciate why this is necessary for One Design boats. My local sailing club races all boats at one time and has a handicapping system. One Design rules do not apply.

    My improved dagger board and rudder

    Thank you - yes, the legacy of the early Sunfish dagger board left us with only 27/32" for the maximum thickness of the board. If the full width of the trunk is used, this results in a maximum thickness ratio of only 8.8%, far below the optimum for such conditions. If you look at the FRP...

    My improved dagger board and rudder

    Many thanks. You are a skilled craftsman and your work is impressive. I am wondering why rudders and dagger boards are not built more like aircraft wings, with a central spar running from the root to the tip? They are essentially the same, and the loads on them from dense water are quite...

    My improved dagger board and rudder

    On our lake, anyone can race any sailboat and in any condition. No One Design events here. Most sailboat owners are recreational sailors, but that does not mean that they do not like to see how well they do against others. Sort of like street drag racing. Welcome to the South, y'all!

    My improved dagger board and rudder

    Why do people climb mountains? It is an engineering challenge, and I like that. The current foils also have a lot of drag during maneuvering and I hope to quicken tacks. I doubt many people would want to sail with the original dagger board - the FRP ones are nice, but could be better...
