So far so good 21' Tidewater cc Hard T-Top. Holds up well for winter PA month. Last month there was a lot of rain, snow and wind. That way I can go outside and work on the boat when the temperature rises enough, enough sunlight to shine and enough light to work inside. I'm one size for my boat (20-22) and it closes the Yamaha 150 and I can climb through the back next to the engine with the latter's small step. Hope it goes on. Very happy with this purchase so far.
