Repair a hole through a board

Post by Francois Dubois » Wed, 18 Feb 1998 04:00:00


I need some advice on how to repair a hole that goes completely through my
old board. I will give an old Fanatic Cat which I had for a long time to my
brother who wishes to start to windsurf. The only problem is that there is
a pretty big hole which goes completely through it next to the mast track.
Epoxy is not a possibility since the hole is just too big and I should
secure the mast track.
Any advise on how to repair such a damage on a production board would be
greatly appreciated.

Thanks in advance,
Francois

Seems to be a bigger job to be done, so all advice from the far is to be
taken
with some caution. Otoh there probabely isn't much to loose.

First you should remove all loose material (skin + foam) and let the
core dry
out if necessary.
Then the hole in the foam needs to be filled. This can either be done by
inserting a piece of foam (eps or styrofoam) fitted to the hole, using
epoxy thickened with microballoons. Or you can use some expanding
Polyurethane foam , either from the construction sector (=> home depot
or however these shops are called in Hong Kong, the stuff used to
insulate
windows) or, preferably , a light 2 Komponent liquid self expanding
PU foam.

Then sand the foam flush to the deck, roughen the skin surrounding the
foam and
laminate the place with glass and epoxy. 4 - 5 layers of 4 - 6 oz. glass
should be enough. Let the epoxy cure, sand and apply top coat (normal
epoxy does the job as well), cure, sand, paint, redeck.

If you need to fix the mast track additionally you need to use your
imagination: Is it enough to pour in some epoxy (!! don't use too much
or a fast hardener, you will melt the core otherwise !!) or is some more
fixation
needed. Normally the tracks are screwed in in production
boards so if the screws still are there and in "good" material
i wouldn't worry too much. Otherwise you'd have to rebuild a bed for the
screws.

Good luck in getting the ship seaworthy again !

Repair a hole through a board

Post by Mike Englan » Thu, 19 Feb 1998 04:00:00

Hello All,

I'm thinking of upgrading my old F2 Bullit Race (9'8", 112l) with a more
modern board. This board will be my light-wind board and will be used
mostly with a 6.5 or a 7.5. I had originally thought I should look at
boards in the 295cm, 130l range. Should I consider boards in the 285cm,
115l range too, or will the planing performance suffer too much? I'm an
intermediate, weigh 175-180lbs and sail lakes and bays in NJ, PA and DE.

Please send me your recommendations, advice and input.

Cheers,

Mike

PS Appologies if this message appears more than once... I'm currently in
news-group hell.

IMHO, at your weight, I'd go bigger, but not knowing the wind range you get
"most" of the time makes a recommendation difficult. If you have wind speed
over 12 mph most of the time, then a 295 will be O.K. with a 7.5.
If the wind is often down around 9-10 mph and you still wish to sail your
7.5 then something in the 300-310 cm range with 140 liter+ volume will do
the trick. The 310-II  Xanthos, Fanatic Falcon 304, 305 Thommen; or AHD 310
will get you planing in about 9 mph with a well tuned 7.5. This might
double or triple your planing time.
The 285 range would be good, but you'd enjoy it most  if the wind was at
least 15 mph. Sounds like yo already have a higher wind board. The big
early planers all do really well in the 8-18 mph range. Some go a bit
higher in windrange, others do not.
Hope this helps

Just for some reference, I have a 282 Fanatic Falcon in Carbon and it is a
dream in light wind and not too choppy conditions with a 7.0m race sail. I
an bit lighter than you so you should maybe have a look at the new 288
Falcon or the model larger. A friend of mine has the F2 Sputnik 290 and
uses the same race sail but in 7.5m size and usually I get planing faster
and can go up-wind much more, but in down-wind his board is more
comfortable.
