With your particular needs relative to your girl friend I'd probably
build the bigger boat, but in almost any other case I'd go with a 12-
14 foot rowing boat.
I'd be interrested following your choice and the results.

modeled it in Freeship, (because I was concerned that shortening the
station spacing would change the 'rake' of the side panels).. I
checked this and found that 11 inch stations does change the rake, but
only a small amount, about the width of a sawkerf.
Beware that Surf (which has a pointy stern) 4 inches, is quite a bit
different than Junebug, which has a wide transom, 24 inches.
Concerning stability, width and pointy ends are a 'trade off'.
Predicting the stability is anybody's guess, but I suspect that they
are about equal.

How about a quick and dirty Pickup Squared by Jim M.. It's already 45"
wide and 11' long. Outside chines glued up with PLP, polytarp sail,
etc. Should come together with stolen hours between now and September.
Then build something else fancier if you like.

Bruce, why would shortening JB increase stability? If
the beam remains the same won't stability decrease as
you reduce the length, and thus volume, of the boat?
Anyway, I think either length June Bug would have
great intitial stability.

You're right, I should have checked.
I'll shorten a Surf (Crab Skiff) 15'6"X 3'7" by building on 11 inch
stations and the width will be perfect as she'll end up at 14 and be
wider.
Plus that clipper bow stem looks so cool!
Thanks.

Yes, it sure looks like the maximum possible stability due to the wide

If you wanted to increase that stability, I suppose stability could be
increased by upping width from the existing 3' - 3 1/2".

Any thoughts on how an 11/12th. shortening of a June Bug to 14 foot 6
inches would work out? I'd simply lay her out on 11 inch stations
instead of 12s.
Would I lose much in speed as I gained a bit in stability?
At that legth she'd be a tad lighter and easier to slip in and out of
my short box pick up.
My girlfriend has advanced Multiple Sclerosis and we need all the
stability we can get. I've managed to get her in and out of Twisted
Seagull a few times, but it was a close run thing. TS has a great amout
of side flare and loves to toss the crew out next to the dock. If she
were tossed, there's no way I could get her back in the boat.
