Wayne, I have the 17 and I keep her in the water 6 months a year, it makes it so much easier. There have been no problems whatsoever with this arrangement. We rode out the hurricane last year and came thru without a scratch and we had wind at 65- 70 and 3 footers in the creek where the marina is located. Just took off the canvas and added an additional line and that was it. Never had a blister problem only some sun damage to the hatchboards and the need to clean the teak. If its just 2 sailing the 15 is a good choice but if you want 4 people for a daysail you will want the 17. The cockpit on the 17 is outstanding and very comfortable and the cabin will provide sitting headroom for 2. Both are great sailing boats, I'm partial to the 17 but if your leaving her in the water it might be the better option. Good luck with your search, you will definitely enjoy either one. Gary
