Boat covers are one of those items that seaman hope to only purchase once, but usually end up having to purchase several times throughout the life of the boat. Poor construction and less than par materials have weaknesses that are tested each and every day outside in the environment. However, with Shoremaster boat covers, mother nature can throw out her worst, and their intelligently designed covers can withstand it all. This is because Shoremaster uses quality materials and reinforced “stress” areas that are specifically made to last through the life of the boat. Even the thread used is mold and mildew resistant.
