Re: Stepping on seats to get in or out
My cuddy has a starboard side transom door and decent sized swim platforms either side of the outboard. Guests just step off the dock onto the platform and through the door. Really helps out my Dad who's 81 and can't climb over things.
However, my previous boat was a 'step off the gunwale onto the seat' job for him and I didn't worry, I occasionally used a towel if I remembered... at least he spent time with us and we enjoyed many days out on the boat, fishing, talking and watching the World go by.
His arthritic hips are one reason I went for the bigger boat with transom door, but I suggest either way, don't worry about the seats too much and enjoy your boat with your friends and family.
If and when the seats get torn or too dirty to stand any more, recovering is cheap, much cheaper than the cost of worrying about people who step on them.
