[Rhodes22-list] Robert & Roger: - trim rings

[Roger Pihlaja]

Rummy,

You are both right & wrong re the structural value of the trim ring.  If the
trim ring is installed like it was originally on Marc's boat, in what I will
call "decorative mode"; then, you are correct, it contributes no structural
strength.  However, if the trim ring is incorporated into a thru-bolted
sandwich structure as per the procedure in my FAQ; then, it becomes an
integral part of a structural system that is conservatively estimated to be
about 100 times as strong as the port is in decorative mode.  This extra
strength would only be important in heavy weather situations.  If the boat
is only sailed in protected waters & fair weather; then, the strength of the
port will probably never be tested.  There are enough things that can go
crooked on a cruise & I like to sail my R-22 hard.  I hate to install
systems or gear on my boat that I have to baby & always be careful about
because of a built-in "gotcha".  Of course, I also carry several precut
pieces of plywood with a rubber gasket glued on one side & thru bolts to
cover or plug a blown out port.  Everybody uses their R-22 differently I
guess.
