??? ?? I ran across the "luffboard" pdfs the other day, an interesting
addition to the KD860, a much better option than a dagger board or
centerboard, and ironically it reflects the thought that always crosses
my mind when I see photos of cats with daggerboards, which I consider
too vulnerable.? Richard Woods for example offers the option of
daggerboards or mini keels, one too vulnerable to damage, and the other
reduces the draft too much.
??? On a hull with the shape of the KD860, it's a natural solution,
because the support is relatively simple.??? Leeboards are an excellent
solution for sailing craft, but tend to be ugly and look like an
afterthought, due to the need to angle them outward to get the desired
effectiveness.?? On a multihull, with it's narrow hull as compared to
monohulls, and broad beam........ and shallow heel angle, it makes
excellent sense to simply follow the hull on the inboard side like this.
??? Your outside the box thought process very much reminds me of the
engineer I greatly admired when I was in my teens.... Buckminster
Fuller.?? His solutions were based on reason and logic, with a touch of
brilliance, rather than on convention. Other teens were obsessed with
rock stars, movie stars, and sports heroes........... I would have given
my eye teeth to have had the chance to sit at Buckminster Fuller's feet,
and hopefully to absorb some of that brilliance.
??? I'm wondering if any KD860's have been built with these luffboards,
and how they have worked out.??? They are not deep, but an asymmetric
foil operating in water can produce a lot of force.
