I've paddled a fair number of boats in the capacity of instructor and rescue practice partner. I've done t-rescues on many more than I've paddled. It is a lot of no fun rescuing a boat that doesn't have some way of limiting the water that gets inside in the case of wet exit. I tend to have both bulkheads and hatches on my boats. I put float bags into them as well. Makes it easier to limit water entry in the case of wet exit, and I want the person rescuing me to have as easy a time of it as possible. If I got dumped, the water is likely exciting enough so that there is no need for the extra excitement of trying to deal with an almost full boat.

By the way, I am a big proponent of deck lines for the same reason. I won't go out in rough conditions with someone who doesn't have em. I'd rather not risk either their safety or my own in case of mishap. It's fine to have a smooth boat if there is never a chance of going over, but in the bouncy stuff, you want to provide plenty for the rescuer to grab on to.
