These little sling labels can prevent costly damage to boats being hauled out by travel lifts. They show travel lift operators where to position the slings to avoid propeller shafts, saildrives, speedometer transducers, etc. Slings should also be positioned where bulkheads support the hull.  These labels are stickers, so they will conform to the curve of the boat's sheer. They are durable, and hold up to sunlight. They are also recommended in ABYC Technical Information Report TY-28 "Boat Lifting and Storage."

They are sold individually - 4 are needed per boat .  Size is 1.5" x .5" Rectangular.
