I bought a new (to me) ARC 21 and the drain plugs for the hulls are missing. I tried to buy some replacements from West Marine but they didn't fit. Anyone know the thread size for these? Looks like NPT (National pipe thread) but I'm not sure. Thanks Gary

I don't think the drain plug threads match a recognized standard and are likely unique to each manufacturer.
The plug on all ARC, RC & SuperCat products has always been a Ronstan product. If you cannot find them locally, we have them and can ship to you. Please email

Thanks Matt. I did find the missing plugs at the bow end of the sail storage tube on the trailer. Had to send my pet Chihuahua in to retrieve them.
