Now that the project has started to take form, I thought I’d move this discussion over from the the “Footy in 6 Inches of Water” thread.
For those who don’t know what’s going on, I’ve chosen to take on the task of building a boat that fits the Footy class rules, is capable of sailing in shallow ponds, and as it happens, pushes the edges of existing design parameters. To date, I’ve received equal parts encouragement and skepticism.
I’m hoping this thread will be limited to design contributions and that discussion about the rules, opinions about the boat’s viability, and implications for the class will be taken elsewhere. That said, here’s what’s on the table …
Project Blue Sky
A hull and rig taking full advantage of the box rule. Once assymetry is introduced as a design option, the parameters of what is possible expand significantly … lwl expands to a theoritical 18 inches (see attached diagram) and a displacement as light 200 grams becomes practical.
Initial thoughts point towards a rig that cants towards windward, while at the same time pivoting or sliding towards leeward. (see attached diagrams)The work of Jon Howes www.monofoil.com and Gabriel Elkaim (http://www.soe.ucsc.edu/~elkaim/Documents/ElkaimDesignCat.pdf#search="wing%20mast%20bearing" is instructive, pointing towards potential solutions as well as giving fair warning.
Foils are an area which will require a great deal more research. To date, Doug Lord has contributed his working knowledge and others have begun to offer suggestions and sources. It may or may not be possible to build a boat of this size which foils … to the best of my knowledge, it has yet to be done.
Platform will be developed last. At this point, I have no preconceived notions as to how it will look. That said, a rudimentary sketch of a canoe bodied mono is attached. Should leeward bouancy be required it may make more sense to build a catamaran.
For now, no testing has been done and no decisions have been made.; these are early days in the design loop. Any thoughts or advice is and will be received with gratitude. Take a look at the pics and please throw whatever advice you’ve got my way … we’ve got all winter to talk.
In the meantime, I will use this thread to provide updates of the project’s progression.
Much regard, Trevor Paetkau
