Subject: Bulkhead cracks?
Info: (21768 views) Posted: Wednesday 11-15-06 06:08:05 PM
Hull #100 has the vertical legs going all the way down to hull. Also has 1/4 inch thick fiberglass mat bracing attached to horizontal leg and underdeck. Can't say if the latter is stock.

:: Yes, Desoerado's are ash braces too, about 2 x 2 with
:: the horizontal split and revse grain glued once and legs
:: twice.
::
:: Desperado has fore and aft horizontals and vertical legs
:: full legth foreward and half length aft. This is a
:: little over built.
::
:: I've seen both sides 1/2 marine plywood frame glued and
:: thru bolted which seems to work.
::
:: Two things to look for in assesment are the length of
:: the forward legs, 1)

:: do they extend to within 1/2 to 1 inch of the inside of
:: the hull
::
:: They should not be retrofiitted to touch or compress
:: into the hull..
::
:: 2) Beyond the compression cracks is whether or not the
:: bulk head is actually warped forward from the forward
:: base of galley and chart tables If not, it might be a
:: simpler fix.
::
:: Its harder if you have to relieve the bulkhead upright
:: and into a vertical plane agiain.

:: :: My deck supports on #107 are 2x2 ash pieces in front of

:: :: V-berth to the hull to which they are securely tabbed.
:: :: I've seen no signs of deck compression under the mast.

:: :: :: Hi: Dave:
:: :: ::
:: :: :: The rig of you boat is compressing through the deck and
:: :: :: warping the upper horizontal bridge of support.
:: :: ::
:: :: :: The legs which hold up the horizontal support on the
:: :: :: front side of the bulkhead may also be warping . . .and
:: :: :: the bulkhead in plane can itself warp and buckle.
:: :: ::
:: :: :: The first 30 boats all suffered this compression issue .
:: :: :: . . where the legs of the support do not tranverse the
:: :: :: flat plane of the V-berth all the way down to within an
:: :: :: inch of the hull. Your's may or may not. Mine do now.
:: :: ::
:: :: :: I had the horizontal wood pieces fore and aft removed,
:: :: :: the vertical legs removed, new full length legs forward,
:: :: :: partial legs aft.
:: :: ::
:: :: :: Beefy'er timber was used on the Deperado's upgrade. Some
:: :: :: people simply sandwiched the bulkhead with two pieces of
:: :: :: marine plywood.
:: :: ::
:: :: :: A jack is sometimes used to push the bulk head
:: :: :: upstraight again prior to regluing the new beefy'er
:: :: :: supports.

:: :: :: :: I've got a small crack in my bulkhead. Anyone else seen
:: :: :: :: similar problems? I've got some ideas of how to fix it,
:: :: :: :: but want to see if anyone else has some prior experience
:: :: :: :: with this repair on these boats.
