Centerboard holddown: some use bungees, I find it stays down by itself above a beam reach, you want it up downwind. Bigger problem for us is the CB rattling down when running DDW. Hence the red T-handle in the pics; it loops over a hook on the bulkhead.
Rudder holddown: typically rigged with a looped cord, one side pulls blade up, one pulls & holds it down. One or two cleats on the tiller to keep it there. Alternatively, tighten the axle bolt. Don't sail w/ the rudder the least bit up; it will steer like a truck and possibly tear the transom off.
Bailers. Oh yeah. Recall the warning about leaky bailers in my first post?
Those are they. May just need wiping and lots of Vaseline on the bottom plastic bits. Some people manage to replace the O rings. Make sure the tubes are clear of seaweed, rocks or other debris; pull the black collars all the way up
, hard; then finish with a 1/4 twist clockwise. They'll probably still leak, but they should leak slower.
Glad you got out! And remember, if you can sail 1 hour for every 3 hours of boat work, you are doing fine.
(True for all boats.)
