Standard use Laser hull covers come in three types of material. Sunbrella which is acrylic and holds up to the sun’s UV well, breathes well, but is generally recommended for storage covers only, as the material does not hold up well to the abrasion caused from trailering or car topping. TopGun which is a polyester material that breaths, holds up well to UV is abrasion resistant and is generally the best all-around choice. The third consists of various economy materials which are good and save you money, but may not perform as well as other choices.
Shock cord in the hem and cross boat straps are the standard. Covers with reinforcements at the bow and gunwales where the dolly upright supports make contact add life to covers. Some covers come with reflective tape along the stern for safer trailering.
Full Boat Cover
The all-in one full zip cover is great for total boat protection, but does not give you the option to remove just the top cover and rig your boat on the dolly with the bottom cover on only, or just cover the deck (and your gear in the cockpit) overnight on a dolly with the bottom cover off during a multi-day regatta.
