FORESPAR STA-PLUG

Here’s a gift you hope never gets used. Its soft-cone-shaped design allows it to fill the irregular shapes of hull-impact breaches, as well as any round hole leak from a hose or through-hull. Edgegripping riblets help hold the plug in a hole, keeping water out, sealing a leak near the edge where a tight fit is crucial, and holding the plug more securely in place. $19.95; forespar.com
