Hi Joe....
That's the ticket. Never raise the main to the very top. I usually raise it to
the top and lower it
so the boom is about 19 inches up from the mast base. Tie in the boom downhaul
and raise the
sail-stop just underneath the boom.
There is some room to shorten the boom on the boats with a loose footed main.
(all the boats I build)
Simply remove the gooseneck, cut 1.5 inches off, square and clean, press the
gooseneck back into
the boom and drill a #25 hole, follow with a 10-24 tap, install the stainless
machine screw. (do it in two
places off set from the old holes in the gooseneck. which you can't see anyway)
Should take 15 minutes.
Joe, I posted a few photos of your Idasailor Rudder on the Montgomery
Trailersailor site. How is that
rudder working for you?....any complaints?
The reason I ask is WILLI on Strawanza is wanting one for the next leg of his
solo world trip.
His M_17 is on the hard while waiting for Typhoon Season in the Indian Ocean to
pass. He said a couple
of times the fixed rudder would get stressed out in horrible storm conditions
while lying ahull. The boat
would be sliding down the backside of a 40 foot wall and the rudder would DIG
sideways....he wants
to be able to LIFT the rudder totally CLEAR of the water in these conditions
and we are probably going
to beef up a new Idasailor rudder for him (more stainless gussets) and AIRBORNE
it to Vanuatu.
Fair winds
Bob
