Everytime you add a foot it makes a huge difference.I had a 17.5 ft fish and ski sea nymph it did everything I wanted it to do except when I went to lake O.I had to pick my day's waiting for good weather.I now have a 19 ft (18.6 inch)starcraft islander.It is a foot wider and has very,very deep sides.It almost seems like twice the space even though it is only 13 inches more.I am also out of the weather better than the fish and ski(it had a full canopy but was open in the center below the glass)this provided a good cold wind path in the spring.I really enjoy the extra comfort of the cuddy up front.Good luck.polebreaker
