[Rhodes22-list] another rudder problem

[SVTRITON at aol.com]

hi all
while sailing this weekend..(not yesterday winds were 25-35 in baltimore) i 
suddenly developed a great resistence in the tiller and a loss of control...i 
turned around and saw that my rudder had popped up....the stopper thingy had 
released...i was not aground and was doing about six knots on a beat, crossing a 
power boat wake....i reset the rudder pushing the stopper thingy back in but 
it popped out again...this happened about 4 times so i just tied the rudder to 
the tiller to keep it down...my question is do i have to get a new stopper 
thingy or does it adjust in some way???
thanks for the help....o i used my ups on friday in about 10 knots of 
wind..on a broad reach...worked like a charm..but i found out that when the wind dies 
the ups doesnt help much
best
tom
