Default Question ,,,, something I just never did ..

In my former life as a sailboat Captain [ that mean's I paid the bill for
the loan ] I never had to replace, rebed, or reattache, or put on new
........... hardware. Things such as cleats, winches, etc.

Could someone tell me the correct way to go about doing this with a
fiberglass boat.

Say, a cleat. I understand that there must be a screw, or whatever that
goes into the deck to hold the cleat in place,,,,, what about sealing the
deck. And, on the inside of the deck [ below ] is there a backing plate
that the fastener of the cleat goes down through? What type of bedding is
proper.

Just a quick go through.

Thanks ,,,

Better use S/S bolts w/large washers.

deck.


Seal with 3M 5200 or Sikaflex

Yes, a wood backing plate works well.

I like 3/4 plywood with round corners and bedded with thickened epoxy.

The way I am doing it, right or wrong:
Locate your bolt positions and drill through the deck.
Set the fitting and tape around it with masking tape.
Remove fitting and apply a bead of 4200 around the perimeter of the unmasked
area and around the bolt holes. (5200 is to hard to remove without damaging
the deck down the road.)
Through bolt the fitting with a backing plate at least as large as the base
of the fitting. (I am using 1/4" 5083 aluminum because I have a lot of it
and it is easy to cut and drill.)
Tighten down the bolts just a turn or two past finger tight.
Remove the masking tape, clean up and let the 4200 cure for a day.
Tighten down the bolts fully so that the cured 4200 is in compression.

What about the Gougeon Brothers' recommendation that the deck core be sealed
by boring the hole oversize, filling with thickened epoxy, and then drilling
the proper size hole in the epoxy; before the bedding and backing?

If you do this, you should try to make the first hole only
slightly oversized; if you drill away too much of the skin
laminations then your deck fitting will be attached to epoxy
filler rather than the deck.

A better way is to use a small angled tool to dig out the
core from around the bolt holes, then fill between the skins
with thickened epoxy. And use hi-density stuff that will
take the compression of the mounting bolts. Alternately, you
can dish out the skins and lay up some new cloth over the
sealing filler at the bolt holes.

Doug,
This is a very serious problem if water should get in between laminations.
Although my boat is steel, the teak deck margin planks extend over the 12"
steel deck margin plate which extends all the way around the boat. I had
water leak through the cleat bolts between the teak and steel margins and
cause corrosion. The repair caused the destruction of the margin planks
(5200) and was very expensive and time consuming to repair.

My solution was to use plastic tubes that extend from the backing plates to
the teak surface caulked in place with polysulphide. Then use bolts as studs
from the backing plates through the tubes also thoroughly caulked with
polysulphide at the topside and the cleats then mount with nuts and washers.
Leaks solved with insurance.

That's a good solution. If the stuff in the middle is either highly
compressible (like foam) or highly water-sensitive(like steel), then G-10
(fiberglass-epoxy) tubes are a very good thing. Has anyone found a
lower-cost supplier if this stuff than McMaster-Carr?

It depends on the load on the fitting. Very lightly loaded items get
screwed to the deck with a sealant (NEVER 5200!). The most heavily loaded
items like winches and clutches and mooring cleats get the treatment in
which the holes are drilled 2x oversize, and filled with cabosil /epoxy
putty. When they've cured, they're sanded flush and drilled again the size
of the bolt. Backing plates can be aluminum, G-10 or plywood with fender
washers.The hardware and backing plate are bedded.

I recollect that in the West System website (or maybe in epoxyworks) is a
more structured analysis of what's appropriate for a given situation.
