[Public-list] Main Hatch Cover Replacement

[Cole, Andrew L]

John,

I have a suggestion for your hatch slider as an alternative to several
longitudinal pieces of wood caulked in between.

My wife and I recently purchased Alan Kefauver's boat, Andante.  Alan
built a new slider by laminating fairly thin and flexible wood
alternated with fiberglass to a thickness of somewhere between 1/2 and
3/4 inch (I have not taken it apart so I'm not sure how thick it is).
The slider built this way is extremely strong, I can stand on it without
any flex whatsoever.  The appearance is attractive (although ours
desperately needs to be refinished), an uninterrupted span of whatever
wood you use for your top lamination.  The slider fits under the sea
hood that is installed on our boat.

If it would be of any help, I have the jig that Alan built with which to
laminate the curved part of the slider and would be happy to loan it to
you (or anyone else looking to rebuild a slider).

I believe Alan also built the new hatch boards which sound fairly
similar to those on your boat, I don't have any helpful information
beyond what you apparently already know on those, although if you have
any questions, I can pass them along to him to see if he has any
suggestions.

I am replacing the sliding hatch cover and the boards that slide into
the companionway leading from the cockpit to the main cabin of my Alberg
30 "Trelawney". Has anyone done this before, or knows about this, that
could comment? The old ones were made of mahogany. They have been on the
boat since I bought it 21 years ago. They could be original equipment. I
don't know. The boat was built in 1965. I am planning to have them
constructed of solid teak similar to the old mahogany ones. I was
wondering what the different designs of hatch covers and boards (I want
to say the term is duck boards or something like that) on Alberg 30's
are? I am sure there are many different designs and options. The sliding
hatch cover on mine is made of 5 planks running longitudinally and
framed on the outside and with strips of mahogany adding additional
support on the underside and looks to be screwed and glued. There are
grooves between the planks on the outside surface on top which is cauked
with
  black cauking. There are two boards that slide into the companionway.
The bottom one looks to be marine plywood framed in mahogany and the
upper one is mahogany, louvered for ventalation, with screen on the
inside. The aft end of the sliding hatch cover on the underside has a
hinged hasp that folds down over an eye on the upper duckboard for a
padlock to go through. I think I have seen before on other sailboats a
strip of metal about one inch wide and several inches long that is
somehow attached to the underside of the sliding hatchcover and slides
through a slot in the upper duckboard where a padlock can be passed
through a hole in the metal strip. This seems to be a great design.
There may be a company that makes this type of hardware. Has anyone seen
this anywhere. It seems like on what I have seen before the slot was
framed in a bronze looking insert inserted into the wood. I am planning
to have the planks on the top of the sliding hatch cover joined together
by 1 inch internal spleens with the grain running perpendicular to the
grain of the planks to give strength and prevent splitting. I also want
ribs running atwartship on the underside. Any comments would be
appreciated. John
