Pete,

Thanks for the word of caution, but seeing as the old beam has been completely removed, I am pretty much committed to installing a new one. The boat is on a trailer inside a well equipped home workshop so I have plenty of time to figure out how to do it right. Thanks also for the tip about the g10, something I am totally unfamiliar with but will look into.

:: Tim Nutt also had a new mast beam installed and I would
:: caution you that buying the beam is the least expensive
:: part of the operation. It is not a turnkey fit and
:: requires quite a bit of work to glass in properly.
::
:: I was also thinking that g10 might work as a replacement
:: for the aluminum.
::
:: :: Bill,
:: ::
:: :: Sounds like a major improvement. The person I spoke with
:: :: at Schock couldn't tell me a whole lot so I didn't
:: :: realize that the support had been so completely
:: :: redesigned. I'll try to get some more information from
:: :: them but it sounds like a good way to go. Thanks for the
:: :: input.

:: :: :: Both Jan Grygier and I had the retrofit done in our
:: :: :: boats. It makes a big difference in the perception of
:: :: :: interior space. I was under the impression that the
:: :: :: retrofit mast support was a complete unit which replaced
:: :: :: everything. I had the yard do the work, so I never saw
:: :: :: the inside of the structure. My previous support (Hull
:: :: :: #66) was nothing more than a plywood beam, I believe.
:: :: :: There were aluminum tubes connected to the bulkhead on
:: :: :: either side of the passageway between the main cabin and
:: :: :: the forward v-berth for additional support. Even with
:: :: :: the small span between the two tubes, the mast support
:: :: :: sagged and I used a mast jack to keep things kosher.
:: :: :: With the new beam I don't need any of that.
:: :: ::
:: :: :: :: Tom,
:: :: :: ::
:: :: :: :: My bulkhead is in good shape--go figure. Thanks for the
:: :: :: :: tip about the retrofit mast support beam. I called
:: :: :: :: Schock and they still have the kits available for around
:: :: :: :: $500, not including the 5x9" under-deck plate which I
:: :: :: :: believe they have upgraded to stainless steel (they are
:: :: :: :: getting back to me on the price for that one). Now I
:: :: :: :: just have to decide whether to bite the bullet and pay
:: :: :: :: the $500 or to try and laminate my own stringer/beam.
:: :: ::
:: :: :: :: Thanks again for the advice, and good luck with your own
:: :: :: :: boat.
:: :: :: ::

:: :: :: :: :: Steve,
:: :: :: :: ::
:: :: :: :: :: I too am restoring an old S22, #194. My mast support
:: :: :: :: :: beam was o.k. but my bulkhead was rotted and needed
:: :: :: :: :: replacing. If you need info on replacing the bulkhead, I
:: :: :: :: :: might be able to help.
:: :: :: :: ::
:: :: :: :: :: On the subject of the laminated stringer/mast support, I
:: :: :: :: :: believe there is a retrofit replacement available from
:: :: :: :: :: the builder, Schock boats. Their phone number is
:: :: :: :: :: 951-277-3377. Might be much easier than building and
:: :: :: :: :: installing a new laminated beam. I believe someone in
:: :: :: :: :: the S.F. fleet has already installed a retrofit piece. I
:: :: :: :: :: am sorry I do not recall who that was.
:: :: :: :: ::
:: :: :: :: :: Tom
:: :: :: :: ::
:: :: :: :: :: :: I am in the middle of restoring a Santana 22 that I
:: :: :: :: :: :: recently bought (1968, hull #365) and upon removing the
:: :: :: :: :: :: chainplates I discovered that the 2"x10" laminated
:: :: :: :: :: :: stringer that runs under the mast was thoroughly
:: :: :: :: :: :: water-logged and mostly rotten. I cut away the interior
:: :: :: :: :: :: fiberglass and removed the decaying stringer and
:: :: :: :: :: :: discovered what was left of a 5x9" aluminum inset plate
:: :: :: :: :: :: directly beneath the mast that had mostly turned to
:: :: :: :: :: :: paste. I guess I have two questions; I was wondering if
:: :: :: :: :: :: anybody has experience and could give me some advice on
:: :: :: :: :: :: laminating and installing a new stringer; and what
:: :: :: :: :: :: should I replace the 5x9" plate with--stainless seems
:: :: :: :: :: :: like a better way to go, but it appears to have been
:: :: :: :: :: :: nearly a half inch thick. Any help would be much
:: :: :: :: :: :: appreciated. Thanks,
:: :: :: :: :: ::
:: :: :: :: :: :: Steve
