Sea Tow Reports Increased Boating Activity and Calls for Assistance Midway Through July 4th Holiday Week. Incidents Underscore the Need to Follow Commonsense Boating Safety Guidelines. The extended July 4th holiday has been one of the busiest in recent years for Sea Tow Services International Inc., the nation’s leading on-water assistance provider, and its network of Sea Tow locations across the U.S. This increased activity reflects a growing desire among boaters to enjoy the many benefits of the boating lifestyle with friends and family. By midway through the July 4th holiday week, which runs this year from June 29-July 8, 2012, Sea Tow already had received more than 2,200 calls for assistance.
