Here's how I see it.
For the occasional user, a PVC boat such as the Aquamarine is just fine. For the frequent user, a hypalon boat is the way to go.
Hypalon is somewhat sturdier and much lighter, but PVC is much cheaper. Other than that, there is not much about it.
I am on my second Aquamarine 10-footer. The first one gave up the transom after six years of use. It was my mistake, I stored it for the winter without drying it out thoroughly and the transom rotted. Repairing the transom would have cost me the same as getting a new boat from Aquamarine.
The reason I recommend Aquamarine boats is Michael, the owner of the business and his extraordinary customer service. Plus, it is a local company (Richmond) and the price to quality ratio is just right. The new red and black Aquamarine boat which is already set up for fishing looks amazing. Sure beats having to pimp it yourself.
Good luck in deciding. Buying a boat is always a nice adventure.
