[alberg30] Support Beam

[Guy Lalonde]

From: Guy Lalonde <lalondegc at videotron.ca>

Jim,
those without a liner (approx the first 400) have a wooden support beam and
those with a liner have an aluminum one. As per the maintenance manual very
few of the aluminum support beams have failed, and it appears to be more
common on high tension rigs set up for racing. The aluminum support beam +
bulkhead system rest on the hull liner and reportedly on some boats (like
mine, #466) there is no support  under the liner for about 12 inches each
side of the centerline. This may cause the liner under the bulkhead to be
depressed. On one of the boats, the depressed liner closed off the water
hose beneath it. There is a suggested fix in the manual (page C-4).

To all the racers out there: what tension would be considered "a high
tension rig" for an A-30 ?  900 lbs?  1,000 lbs?  More?

Jim: is "Barchetta Mia" italian and does it mean "boat of mine" or maybe
"small boat of mine" ?

Guy.
Cyrena #466
