Porta bote drain plug any one..or porta bote hacks.

[Mg451]

I have a potato bote alpha 10ft with a 6hp 4 stroke. It gets up and goes and I've had it in some rough seas feels pretty safe once you trust the flexing.its been drug over Coral and barnicles, tied to cliffs with pounding waves, used as a fender , dropped many sharp objects . Tied up to many bridge pilings with sharp nails... I'm sure happy with it. Not perfect but deff better then I expected. I need to add a drain plug So i can put it on davits with out fear of it filling up. All I've found was starboard side as far down and aft as possible.. any one added a plug to theirs ?
