I think you have gotten a sweet deal on the 15 footer. The one on I-Boats is located in Ca. Which is a long way away as well as most likely high shipping costs. I think if it was me that was buying it I would want to get one closer to home than Ca.. The 15 footer will also allow you a little more room. I am not real sure on how it will be getting in and out of your hot spots though. As with in most cases more room means more gear will most likely be added. Good Luck on what you decide..
