My sprit appears to need some work. There is some slight delamination just =
starting to happen. I'll be removing it this fall. Any info. on removal and =
repairs?

For some unknown reasons, I found that my Baba 30 bowsprit has lifted.

There is a bolt that goes throught the bowsprit into the stem - but, this=
 
seems to have loosened up. It is not broken (as Quernica reports their
bolt broke).

The bobstay is very tight.

And, at the same time, the whisker stays suddenly are slack.

I loosened up the backstay and the gap remains.

The whisker tay and bobstay were all adjusted last season when new
replaced and it is strange the whisker stays went slack. It is almost as
if the stays streched out.

The turnbuckles were pinned and taped.

This is a mystery.

While researching this, I found the following on the westsail site
http://www.westsail.com/:


BOWSPRIT ATTACHMENT AND STAYSAIL EYEBOLT


In order to control the headstay tension, the headstay must be sufficiently=
 
tight so it will not move. The key to this is the eye band staying in one=
 
place and only one place. If the whiskers, bobstay or bowsprit are loose,=
 
there can be movement. The load is taken by three 1/2" bronze bolts that go=
 
through the bowsprit and deck. It is possible that the wood can be creeping=
 
aft on the bolts under the tension, and that the rig is losing tension. We=
 
have talked to people who have pulled the bowsprit bolts and found them to=
 
resemble a bent letter S.

The 1/2" bronze eyebolt holding the staysail stay has broken on a number of=
 
occasions that we know of. The stemplate that attaches to this eyebolt and=
 
the stem of the boat has also broken on the bend, if there is any slight
movement of the bowsprit. This piece should also be carefully inspected
very frequently.
WOODEN BOWSPRIT DELAMINATION


Regarding delamination of the bowsprit, we have seen this happen on a
number of boats that have been inspected, as the glue breaks down and lets=
 
the boards separate. If the wood is still sound, with no signs of dry rot,=
 
then scrape off all of the varnish, and force some epoxy resin glue (such=
 
as West System) into the gaps between the boards to fill it up. Next
saturate the bowsprit with at least two coats of the epoxy resin to seal
the wood, including all of the holes for mounting the rollers and platform.=
 
You can them varnish or paint over the resin. If you have to replace the
bowsprit, we would suggest making it out of one piece of fir, or at most
two pieces with just one vertical seam. Use epoxy resin to glue the joint,=
 
and seal the wood before varnishing. We also have a stainless steel
bowsprit available if you want to replace the whole thing.
