This is our 2nd summer with a cabin on Winnisquam so I am in a similar situation. In the past 4 years we have rented over 10 different boats, including 6 last year, once we had our own dock. It was nice to see what fit and how they rode while tied up. It can be very frustrating being on shore with no boat, but I'm glad I took my time.
We tested pontoons , tritoons , deck boats and V hulls. I even built a wooden kayak over the winter. Well after all that testing the two standard Poodles let us know they liked the Pontoon style best. It's a very big purchase no need to rush into it. With that said, We may be boat owners tomorrow,
will update this weekend.
