Brian - you read my mind. I'll be installing bulkheads shortly, and while I originally planned to use the bulkhead as footrest, I thought I'd better install it conservatively (ie. forward of "perfect") and use foam to adjust.

I'm 6'5", so I doubt any borrowers would need the footrests much further forward than I do, but to allow for fine tuning, I figured it'd be best to have an inch or so to play with.

And to address Pete's warnings, the foam could have a gap in the center, to accomodate the occasional leg stretch.

: I would suggest NOT trying to install it in the "perfect" position,
: since that may be a moving target. Set it an inch or two forward of where
: you think you need it and take up any slack with minicell foam padding.
: This allows you to compensate for differing footwear, etc. I've had four
: commercial boats where I was forced to use the bulkheads for footrests and
: a couple of skin boats with fixed footrests. I can tell you from
: experience that if they're off on the short side, it can be a major pain.
: It's better to err on the side of extra length.
