In Response To: S&G: I have a flat bottomed 12' S&G and... (Robert N Pruden)

: ...I want to add a false bottom to improve stability. Anyone have
: any ideas? I am thinking two possible thoughts on this. One, I
: carve styrofoam which has been glued to the bottom, shape it,
: then shape plywood to fit, S&G the plywood on and wrap it in
: glass. Two, Since the depth of the false bottom wouldn't be much
: more than two or three inches, I might layer thin strips of
: scrap plywood to get the rough shape of the false bottom, then
: sand to shape. I don't mind the extra weight since this kayak is
: gonna be my ice breaking ice runner for late fall paddling when
: the river is full of ice. I will add brass to the keel to make
: sure I can run it into the ice without messin' things up. I am
: open to any reasonably uninvolved idea. Am I asking for a lot?
: Maybe, but I want to get this project completed before the river
: freezes up this year.

: Robert N Pruden

My own experience with ice breakers is, stability is most important. Adding a false bottom will likely raise the seat and CoG further above the waterline, reducing stability. You can add torsional and longitudinal stiffness with tubular structures along either side, depending how much width you have to play with.
