[Public-list] Main Hatch Cover Replacement

Wed Oct 26 13:55:30 PDT 2005

Hi Andrew,
My friend has a carpentry shop and will make this for me. He suggested sort of the same thing you have. I am a little hesitant to do it in this way mainly because I have been removing the plywood from the interior of the boat that has started delaminating. I have to say that it did last quite a while, the boat is 40 years old. It is still difficult fo me to put any laminated type of wood back on the boat. My friend told me that the resins used today are far superior than what they had 40 years ago, but in a marine environment, especially on the external part of the boat constantly exposed to the elements, I would feel a lot better having something of a solid construction. My friend has a stock of really excellant Burmese natural growth teak that is hard to come by these days. I wouldn't use it for just anything because it took hundreds of years to grow, but it will be put to good use on this boat and if constructed right, should last 100 years or better. I am only using wood on this, the cockpit seats, the coaming, handrails on the top, toerails, and the tiller. Everything else will be fiberglass stainless steel,or bronze. I want to be sure It is strongly constructed and can support the weight of someone stepping on it which I know will happen sooner or later. I'm not going back to the cauking in between though. That was a real pain to maintain.
I am probably not going to have the louvered hatch board but just put a solid one in there, but I am wondering if I will develope mildew, etc. inside from the lack of ventilation? Do all of the Albergs have this type of vented hatch boards?
John

  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
