TOTAL CONTROL, SIMPLY REFINED

my boat, which is a cored-hull

model. I have installed trans-

ducers in the past aboard

other boats, but none were

cored hulls. Are there steps I

should take that differ from

those required when drilling

through a solid laminate?

John Ramos

Hialeah, Florida

A: Yes, extra care and extra

steps are needed when adding

accessories to cored hulls.

Primarily, you must seal the

cutout, not just the item being

installed.

Once you cut the hole for

your ’ducer, you want to ream

out the core material between

the layers of fiberglass to at

least one half-inch all around.

Then fill this void with epoxy

STRAPPED
Q: Hi, I am a first-time boat-
er. I just purchased a 21-foot
Crownline that the previous
owner kept at a high-and-dry
marina. I will be trailering
and need to buy a trailer
winch. I cannot afford a
power winch at this time, so
I am buying a manual winch.
Should I load this with cable,
rope or webbed strapping?
Susan Harry
Dothan, Alabama

A: Susan, I’d use a webbing
strap, if given the choice.
They are low-stretch, much
less so than rope, and won’t
produce splinters to stick in
your hands like a cable will.
Two-speed manual winches
(windlasses are for anchors)

putty. That will prevent water

from getting into the core

material. Simply painting on

a coat of resin or other sub-

stance will not do a good job.

Next, install your trans-

ducer and seal it with an

appropriate caulk — I’d use

a polyurethane for a perma-

nent, below-the-waterline

installation such as a

transducer.

It bears repeating: Seal the

cutout and seal the fitting.

that much easier for little

extra expense.
