A better choice for the trip to the lake is a travel cover. Travel Covers Travel covers come in many styles. These types of covers are best for towing. The covers are of smaller mass than a storage cover, are lighter in weight, and they snap into place making for a tight fit, which reduces drag. Travel covers are best made from an acrylic material.
Acrylics stretch for a tighter fit and they won t shrink.
Waterproof fabrics tend to shrink and they do not breathe, allowing mold and mildew to flourish in the boat. The shrinking nature of waterproof materials often makes the snaps tear out of the cover, and sometimes the shrinking action will pull the snap out of the boat deck as well. That is a costly repair. An important side bar here is the quality of snaps and how they are attached to the boat deck. Some canvas snaps are attached to boat decks with rivets.
