Todd,
In my 1st post responding to this thread, I referenced the following FAQ,
which I wrote many years ago:
http://www.geocities.com/blew_skies/openport.html
Read the FAQ & if you still have questions; then, ask away & I'll try to
help. As you will see when you read the FAQ, I actually did this port
installation in October, 1988. Thus, I'd only owned my R-22 for about 18
months when I did this port upgrade. After 14 sailing seasons & thousands
of trailering miles, all four of those Beckson opening ports are still in
place and don't leak a drop. The starboard front port once took a direct
hit from a bird while trailering at expressway speed on I-40 in Tennesssee.
The impact ruined the insect screen on the port & put blood & feathers all
over that side of the boat! But, there was no structural damage to the port
itself.

your ports, did you fill the hollow area between the inner and outer walls
to keep the through bolts from squeezing the walls in together, and if so
what material/s did you use?
