Ballast
On my O'day 26 the ballast is in the trunk and the swing board is light weight. On the Cat 22 I owned before, the ballast was in the swing board which required a winch to raise the board. On the 26 the swing board is easy to pull up by hand and easy to remove if repairs are needed. I an not sure what type are on the boats you are looking at, but it is somthing to consider.
