VORTEXTAN/Beige 20' Ultra Pontoon/Deck Boat COVERINCLUDES Support System, HAS Elastic and Straps FITS 18'1" to 19' to 20' FT Long

These are the best boat covers available. They are suitable for STORAGE, MOORING, AS WELL AS TRAILERING. The cover is made from marine grade polyester canvass. The cover is made from 7.8 oz/600d/600 denier solution dyed polyester. The fabric is then coated twice with polyurethane on the bottom or downside, UV protected. What this all adds up to is the best cover available. It is nearly twice as thick as what you see readily available commercially. It is designed to keep water out, as it is WATERPROOF. Yet, water vapor can permeate it, so it will keep moisture out, but will not keep moisture in! 600d is an indirect measurement of density and weight. The higher the number, the heavier, thicker, and heavier duty. This is the thickest cover you will find. You will see a lot of 300d, even 150d covers, which are proportionally half as thick and 1/4 as thick as our covers. These are very waterproof. Included is a two pole support system to create an arch so the cover can shed, rather than collect water. SPECIFICS FOR THIS COVER: This particular unit will fit a pontoon or deck boat with deck or playpen area between 18'1" ft and 20 ft AND A BEAM OF UP TO 102". You can trailer with it, but you have to eliminate the movement of the cover. That is nearly impossible, and it is generally better not to trailer with this or any cover.
