Re: stretched brick
David Grey, I believe, stretched a bolger skimmer to 10 or 12 feet and
narrowed it 6 inches or so. Not the same boat as a brick, but not
dissimilar in the amount of interior framing (basically none).
I just did a tortoise for Spat. It was very floppy right up until I
glued in the longitudinal seat. Stiff as a "board" now. Following
the plans from Build the New Instant Boats and gluing the seat to the
rockered bottom like a curved-bottomed, flat-topped box stiffened up
the whole boat unbelievably.
I'd say go for it. you can always add a front deck or some luan knees
if you have to later. If anything (look at cruising mouse for
example) stretching out the rocker and extending the waterline might
be a real plus.
lets see . . . where is that david grey link . . .
