Hey, Ed, Ben, Rob, Rik, Rummy, Lou,
Thanks all for the info. Based on what I've read, I'm going to replace all
the screws with bolts.
Lou, are you the one who did the write-up with Roger in 2005-2006? When you
say "torque" are you implying you actually used a torque wrench or just as a
euphemism for "tightened"?
My centerboard lift line has a different configuration from that in the
article I referenced above. It starts from a small U bracket fore of the
foremost block on the cap. Since the blocks on the CB were broken I don't
know how it was threaded below, but it seems to have gone from that loop
thru the highest block on the CB, back up to the the foremost block on the
cap (an inch aft of the loop), back down to the lower block on the CB (2-3
inches below the other one) then up thru the aft block on the cap which acts
as a fair lead, then thru the hole and nipple for the lift line. It seems
that there should be another block lower down on the CB to give an extra
mechanical advantage and more pull on the extreme, but I never had any
trouble raising or lowering the CB before the break.
I'm still wondering what sealant/caulk to use. The guy at West Marine
recommended 3M 4200 but I think it is essentially an adhesive like 5200,
just not as permanent. Lou, what did you use? Seems like an underwater
silicone (like Silicone II) would work well. I've never had any trouble
with leaking, but I might as well do it right while its apart. I would
consider changing the gasket but it appears to be in very good condition.
I've been renovating a 1937 house for the past 4 years, so Pathfinder has
been on the hard in my back yard during that time. It wasn't worth paying
the slip fees when I didn't have time to use it. We're replacing the mast
lights... the anchor light lens was cloudy and I lost the steaming/deck
light when a branch fell on it. I'm replacing the anchor light with an
incandescent, but the steaming/deck light with LED. Figure that will help
the battery charging life, and will be installing a solar panel for trickle
charge.
All of the brightwork needs sanding & varnishing and have to clean up some
sap on the deck. Washed all the lines and the sails and she is just about
back to sailing condition. She still looks great even at her advanced age
of 24 years!
I'll continue on with the cosmetic work (screens, varnish, polishingetc.)
over the next year; but we're hoping to get a few sails in before winter
"really" gets here, although the way things are going that may be
optimisitc. Monday afternoon it was delightful sailing weather. Today it
is windy and cold... unseasonably for this region.
Ed, I met a fellow from Richmond a few years ago (Rob, was that you?), but I
haven't run into any Rhodes owners in the Tidewater region. I'm living in
Hampton now.
Thanks all for your well wishes and the great information to help us get
this project completed.

I use 10x24 ss bolts on my cap. I prefer to tighten the nut under
the cap using a closed end wrench with
my electric driver and the correct wide phillips bit in place. Do a
criss cross pattern like lacing up boots
and torque the nut with a rachet wrench with the phillips bit and
just hold the nut in place with the same closed end wrench (7/16")
took me about 1hr to do 46 bolts.
Ive overhauled my entire centerboard cap, trunk and board including
the mechanical advantage
