I have a WM 310 hypalon aluminum floor rib. No build or quality issues. Had the boat 6 months. No bad seams or quality issues. Powered by Tohatsu 20 hp.
Im about to get a WM with my new to me boat next month.
Up till now, my primary inflatable is an Avon 3.1 that is a 1976 model. Its seen tough use in bahamas carrying divers, scooters, lobsters, spears, etc. Thats some 45 years old
I just picked up my WM RIB 350 the other day. I plan to outfit it with a console and a bench seat I got off of craigslist. I am planning to put a 20HP Yamaha on it.
I have owned a half dozen of RIBs and I have a 10 foot Avon high pressure floor model and a 21 foot Zodiac Hurricane. My worst experience with with a Zodiac 380 which the glue was separating from the bolt rope.
