On my ARC 21 the rudders are either fully up or fully down. No middle ground even when I hit a sandbar the rudders go to full up position. I loose all control of the steering in shallow water where the rudders can't be locked down. Help. Dont want to end up on the rocks.

Will an SC20 jib work on an SC19?

I am thinking about mounting a 2.5 hp outboard on my ARC 21 but can't figure out a way to mount the outboard motor bracket and motor to clear the tiller/rudder crossbar. Any suggestions and/or pics out there?

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.

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
