I would consider a small tetter totter on the window to distribute the weight or a pull line hooked to the stern so you could pull up on the stern when you push down on the bow.
: I'm spec'ing out materials for a strip kayak, and looking at layup
: options, I came across a problem I don't hear a lot about.

: My kayak will load/unload from my condo through a window 10 ft. of
: the ground. I'll install boat wheels on a frame that I can stick
: in the window during loading, but that means that when bringing
: the boat up, in order to not hit the celing I'll be pulling the
: bow down and sliding the boat inside, with the boat balanced on
: the loading wheels relatively close to the front of the hull.

: Given a 16'-18' boat, that's a lot of leverage being applied to a
: small area of the hull.

: I was imagining I'd go with a "standard" layup of 4 oz
: fiberglass inside and out, but it occurred to me that I might be
: going a bit light for the forces that would be applied.

: This boat is never going to see a rock (Lake Michigan) so a rugged
: layup is not necessary unless it's to add stiffness for this
: loading issue.

: Any thoughts?
