I'll join in with the Contender modding. There are some cats that work pretty well when sailed either one up or (with a jib added) as a sloop. Part of the key, IMHO, is that they are quite long. The Contender is also pretty long, with a flat hull that wouldn't change its immersed shape a great deal with extra weight added, and I assume they can carry a fair bit of weight in correctors that could be removed. Ben also designed a two-man boat along similar lines that was only (IIRC) 17 feet overall, so apparently he believed you didn't need a great deal of extra length.
So....get a Contender, sit the rig upright to get the foretriangle dimensions right, whack on a jib and kite, play with the centreboard rake and you have a convertible dinghy.

Back in the mid '80s I had a 1960 built wooden Enterprise rigged with an old rules Merlin kite (8m symmetrical) and had plans to add a trapeze but, in the end, decided the poor old hull wouldn't survive such abuse.
You'd have to move the mast step back too.

Isn't that nearly an FD? Beautiful boat!

rs600 with a t-foil rudder (i14 type), high aspect daggeboard, squaretop sail and a masthead kite.
for no real reason other than it would look cool.

Yes, it would be a baby FD, but an FD you could singlehand when your crew could not sail, just as quite a few cats do it.
SS, the mast step is already a long way back in the Contender; pretty much in the same spot as many sloops. Given the designed rake in the centreboard, I tend to think that the balance issue could be sorted by changing it to a more upright angle. By the way, I've seen a Contender fully converted to a two-person sloop with assy and wings. IMHO the wings would add too much weight so you'd be better off with a single trap.

I didn't realise the Contender had a lot of rake in the CB (most, attempt to be vertical for best efficiency upwind). Since this is an enjoyable fantasy exercise I'll bow to your greater knowledge. Contender is certainly big enough to support a crew of two.
Cats are slightly different though as, I suspect, they are less sensitive to CoE shifts 'cos the long narrow hulls track well in a straight line hence they can just remove the jib or add a kite without moving the mast step (impossible on most anyway).

The rig rake has increased massively over time and board rake has had to follow.
CC. from iGRF's desire for a lightweights trapeze singlehander, if a Farr 3.7 is too short for your preference, a L/V3000 with main alone, if a little helm heavy perhaps with a self tacking jib to improve balance.

Put like that it certainly makes sense. The L3k I sail occasionally is a fun boat. Self tacking jib and it would make a decent singlehander (they do race them solo I think)

Maybe the 29er would work well as a single-hander? Certainly the times I've sailed it it seemed more stable than the goods made it seem! They were early on the learning curve.
However, the XX proved that frankenboats don't always work. |
