Reply to: Who was looking for dagger boards for a Nacra 5.2?

Message body

[quote=Wolfman]Thanks EC!  The daggers will be handy to have and hopefully will get me started building my own (and other peoples)!!  If I get a production run going I will pass on the wisdom and parts!  Any other castings available?  I could also use a spare beam, my front beam is getting a little holey after all the bits and pieces I have put on and taken off.  Probably not 
impossible to ship in Canada also.

The culprit for a bow tearing off of a 5.2 is usually the stringer inside the hull at the front beam.  It adds stiffness and strength to the highest stress part of the boat.  They have a nasty habit of breaking away at the hull/glass connection.  Easiest way to check them is to shove a flash camera into the front port and take some pictures.  The stringer itself will be bumpy and ugly (maybe with mold on it) but there should be no loose fiber or obvious cracks especially around the seem.  This fix isn't hard but requires you to notice the problem and take some time.  I have to do this next spring for another problem (some bozo cut through my stringer on  the startboard hull to access a repair).

If you do find a problem you have to reglass the seam on both sides.  The rear part can be accessed through the port, but is a PITA to work through.  You have to clean teh area  with acetone and a light sanding, then add resin and chopped fibers.  Probably better to lay some light matt too.  The other side shoule be easier to work once you get the front deck off.  You can get the front deck off by carefully prying with a chisel and thin pry bar.  To get it back on you can probably use 3M 5200, but most use thickened epoxy.  Best idea is to get a book on fiberglassing and/or watch some youtube videos before tackling it.
