reinforced webbing fabric material that is double-webbed and sewn together for added strength. The handles
are strategically distributed, six on port and six on starboard sides, two of which are in the transom area to
facilitate carrying the boat with heavy engines attached.

Rubbing strakes made of extruded neoprene are bonded to the craft at key wear points. Three rubbing strakes
are fitted to the underhull. Ripple finish rubbing strakes are fitted to the sides and bow section. The rubbing
strakes protect the craft from abrasion and puncture during beaching, docking, and handling operations. The
rubbing strakes are sacrificial and are replaced when worn.
