Old thread but relevant enough to avoid starting a new one...
I just got a new cover for my 20' G3 pontoon. Says it is a towable cover. The one I have now came with the boat and is the snap on style, and I know that can't be towed. The new one has straps to the trailer (24 in total, I got extra). This one also comes down and covers the deck entirely, whereas the snap on cover just covers the furniture leaving the front exposed. I'm hoping the slope of the cover will help offset the drag a bit as well as helping protect the currently exposed bits of the deck.
Anyway, I've seen a lot of threads here and elsewhere, and there seems to be quite a split between YES, you can tow with a towable cover, and NO you can't. I'm not super-experienced with the boat yet so I don't quite understand why so many people advise against towing with the cover on, especially if it is considered a 'towable cover'. Thoughts?
