The answer also depends on how much (if any) your marina will allow your boat to stick out beyond the end of the slip. Where I keep my boat (King Harbor, Redondo Beach) the limit is three feet, everything included. So a 25' slip can (in theory) accommodate a 28' boat. But, as was said above, draft is going to be your main problem. Could be worse, the tidal range in California is generally about six feet, eight feet during extreme Spring Tides.
