Versiplug Micro is the answer to draining the last bit of water that gets trapped in the lowest part of your hull.

Drill a 3/8” hole with the supplied drill bit and then screw Versiplug Micro into the hole using a 1/2” 6-point socket. The Fiber Grip threads will self thread the hole. You may want to put some silicone in the hole to seal the raw fiberglass.
