Don, it's as I stated, the kayak only weighed 60lbs when completed. It seemed to be easy enough to handle at that weight, because of the length of the kayak itself. One person could easily handle it, I loaded it and unloaded it many times by myself. As for having time, you've got all kinds of time. You could always build the top half, then build the bottom half in a year or two times. You could hang the half you complete, from the rafters or ceiling of your shop. This is what I did with a canoe, that I started building to late into the season.
