If your going to be fishing Oceanside 80% of the time I would go for the heron18 as it will be more comfortable. That’s being said the 16 is a hell of a skiff and can handle it’s own on the ocean if you pick your days. I was Oceanside out of marathon on my advent (a narrow heron16) for close to a week and was very very impressed with how it performed. I think with a fold away tongue you might be able to get the 18ft in your garage
