1247.0. "help on fixing an old boat" by TOOK::MCCRORY (Eileen M. McCrory) Tue Jun 13 1989 18:11

    Last weekend I poked a hole in the bottom of a wooden boat.  It's an
    old wooden blue jay (I think - it looks like the kind of boat that they
    have at Community Boating in Boston.)  It's a nice boat but the bottom
    is made of plywood and it's become very brittle.  It's been leaking for
    a while but we've just been bailing it.  The new hole is pretty big so
    it looks like it's time to fix it.
    
    So, does anybody have any experience fixing up old wooden boats?  I
    don't know if we should replace the bottom or try to fiberglass over
    the whole thing.
    
    Any suggestions?

This is a tough one to answer in any simple or quick way- There are several long
notes here about various aspects of fixing old wood boats. Many more questions
would have to be answered first, like conditions of other parts of the boat,
and the experience of the person planning the repair. If the boat is anywhere 
near Framingham I might be able to take a look and make some suggestions-
I like old wood boats!

In gneneral, fiberglassing over old wood boats is not likely to be very good-
it most likely will  wind up much to heavy.

1247.2Replace rather than patchCDR::SPENCERJohn SpencerWed Jun 14 1989 13:409
If it's a "big" hole in plywood, as you say, and the boat isn't all that 
big itself ;-), and especially if the overall condition merits upgrading, 
the best course may be to replace the whole bottom piece (or pieces, if 
you go for it and do both sides.)  The hole may be too big to easily do a
neat fiberglass patch, and scarfing plywood in small boat thicknesses is
tricky.

    RE: .1
    I checked the keywords and didn't see any notes on repair - I'll find
    the other notes on wooden boats.
    
    RE: .2
    The boat is 15ft and the hole is 2-3 inches across.  The hole is big in
    the sense that we can't sail the boat with the hole.  The boat also
    leaks at the seam on the bottom (the previous owner stripped it down
    and left it out for part of the winter).  I consider those leaks small
    holes - you can still sail with them.
    
    The boat is old and not in the best condition.  Last week I was
    thinking that it would really be worth the time to fix the boat up this
    fall.  The new hole is bringing it to the point where it might be best
    to buy a new boat.

1247.4STEREO::HOThu Jun 15 1989 18:5330
    Eons ago I used to compete in schoolboy crew races on the Charles
    River in Boston.  Instead of shells we used plywood "whaleboats"
    built by the local trade school as a carpentry project.  No fancy
    Bruynzeel or anything.  Just good ole A-C.  They were stored by
    the Hatch Shell, outdoors, and were easily subject to vandalism.
    
    The inevitable happened.  We arrived for practice one afternoon
    to find that some one had pounded holes in the bottoms with a hammer.
    After we pulled them out and let them dry out a bit, the coach
    attempted a temporary repair.  He took a peice of plywood scrap,
    smeared it with glue, placed it over the inside of the hole, and
    screwed down the four corners.  Didn't bother doing anything at
    all with the other side of the hole.  
    
    They went back in the water the following day served satisfactorily
    for the rest of that season.  The following season the boats received
    a fresh coat of paint but the temporary patches were still there.
    At the time these boats were over 10 years old.  Just a few years
    ago, after a concert at the Hatch Shell, I saw the boats tied up
    at the dock again.  Looking inside, I could still see the patches
    although they now had many more layers of paint on them.  This was a
    good 20 years after the incident.  
    
    There no great philosophical moral to any of this.  If the Bluejay
    isn't in that great shape, maybe a similar type of patch will be
    enough.  No sense having a patch that'll outlast the rest of the
    bottom or a new bottom that'll outlast the rest of the hull.

1247.5Now you have a hole in the water to throw money intnWJO::SCHLEGELFri Jun 16 1989 14:0911
    Here is a "tongue-in-cheek" suggestion:
    
      Install a self-bailer in the hole!  It sounds like you might be
    needing one!!  (Only kidding)  A plywood and fiberglass patch should
    suffice until you can better determine how much re-work will ultimately
    be required.  Best-of-luck!
    
    Many years ago, I bashed a similar-sized hole in the bottom of a lap-
    straked run-about.  I simply sat my crew in the hole until we got back
    to get it fixed!  (Moral: Don't miss any time on the water!)

    RE: .5
    
    Several of the people that know the boat (and the leaks before the
    hole) have made the same tongue in cheek suggestion of a self-bailer.
    
    We're going to try to put a patch over the hole this weekend.  I really
    wanted to use this as an opportunity to fix up the boat some more but
    we would lose too much sailing time.
