I have a splinter under my skin and it is called the Everglades Challenge. It is a 300 mile cruise down the coast of florida to:
To me it represents a fun challenge I really want to do someday and this goal is definitely influencing my next build. With the purchase of the big MacGregor I am thinking of building a sailboat with a cabin for daysailing with the family and overnighting by myself. The challenge has some "filters" that limit boat choice as follows:
1) must be beach launched from high water mark and everything used must go in the boat with you (lightweight).
2) must be able to take some open ocean (for a sailboat).
3) must be very thin water capable for the necessary inland routes.
4) must be able to go under a bridge (easily lowerable mast).
5) must be able to both sail and be manually propelled.
6) must be able to carry 5 days worth of supplies (including water) on board.
Did I mention it is a challenge? Anyway, I am thinking along two lines.
1) The conservative would be to build something long and skinny that could be rowed as well as sailed. I would stick to a simple unballasted flat-bottomed sharpie shape with leeboards, centerboard, or daggerboard for its thin water capability and light weight. Flat bottomed is riskier because of the open ocean portions of the race. Some of Mickalak's designs fit this rather well (http://www.duckworksbbs.com/plans/jim/michalak.htm). I would look for something 16' or longer with a cabin.
2) The other option that really intrigues me is a catamaran design basically similiar to the weekender by Thomas Firth Jones (http://www.jonesboats.com/weekender.html) but with a whole bunch of changes. Instead of assymetrical and slender hulls which dig deep into the water I am thinking more of symetrical vertical sided (or minimal flare) flat-bottomed hulls (Bolger like) that would float in thin water. In order to sleep in the hulls they need to be 2'3" wide (min) leaving 4' for the middle deck. Another option would be to go with some sort of telescoping arm arrangement but the simplicity of the fixed width (8'6") is appealing. For better turning I was thinking of a centrally mounted centerboard or daggerboard (central pivot point) which takes advantage of the shallow draft flat bottomed hull to be more maneuverable than regular cats. Of course, there are no flat-bottomed cats out there but reading the SCA Nov 2004 issue reveals a possible reason: skinny hulls are faster than wider planing hulls in a catamaran. Has anyone heard another reason for their abscence? Another problem is how to move it forward in no wind or contrary wind. One possiblity is a pedal drive (with propeller) that drops down between hulls when needed (advantage of a cat). Another option is paddles (ugh).
The appealing aspect of a cat are:
1) wider stance and more stability.
2) ability to carry more sail (probably gaff or ketch for low CE) for faster speed (I am mainly interested in finishing)
4) as a occasional cruiser or family daysailer a catamaran would be very interesting (space and netting between the hulls).
Anyway, I thought I would throw this out there for discussion if anyone is interested in brainstorming with me.
