Re: Traveling with or without canvas and max speed.
75 mph, 1000's of miles a year, with custom fit trailering canvas secured tightly in place. I've towed 3 boats this way, and only bought 3 covers so far (one for each boat). If secured properly with NO FLAPPING allowed they will last just about forever, except for the occasional patch job...you gotta keep after even the most insignificant hole or frayed seam or it'll rip open faster than a prom dress...<br /><br />23 years and counting so far, no problem. For extended high speed towing, I recommend you do NOT waste time or money on a "near custom" fit trailering cover ordered from ANY source. You simply need to take YOUR boat with all accessories to a local boat cover maker and leave it with him while he makes the cover custom molded to only YOUR boat. The pricing is more competitive than you think, and they'll custom mold the cover with appropriate padding and reinforcement right around all your accessories...lights, fish finders, rod holders, trolling motors, bimini mounts, windshield corners, cleats, etc. That's the only way to have a perfect and completely tight fit that will put up with extended abuse. Or you can waste money buying a new "custom" cover via mail order every 2 or 3 years like most people do when they get those and try to high-speed trailer with them. Shred city, no matter how good the material is.
