Four subjects loaded a small flats boat with heavy dive gear and anchored about 4 miles off shore.  The ocean swells were about 7 feet and as soon as the anchor line tightened, the bow was yanked under water.  This swamped the small craft.  The flotation kept it upright.  The four subjects had to be rescued by FWC and Coast Guard.  Towboat US brought the vessel to a marina for repair.
