My 2 cents worth is that TWO youth boats are needed. 10 feet and 14 feet.
Got to get these guys when they are 6 years old! 14 footer needs to end up in Olympics so there is a REAL desire to learn and win.
In this country it goes Opti, Star, Laser, Olympics.
12 footer is neither here nor there.
The PT has been a great non trap, one sail, hi tech boat for 30 years. This boat weighs 53 kilos and a modern boat on this theme must be a great idea.
BTW
Windrush 14 was created as a roof top boat. That is why it has the folding hulls. This is a credible 80s 14 footer with a top speed tested at over 18 knotts and easily competitive with a Hobie 14.
I think that the key to a roof topper is the set up ON THE ROOF. If you can create a boat that sits with its beach trolly on the roof you have something that will get to the water without fuss. A light boat and leaving it to the sailor to sort out roofing won't do it.
