Laser 420: Mast safety hazard

Dear all,

Disclaimer: I am dutch and a sailing noob so apologies if I do not use the correct English terms

I have a laser 420, sadly the mast holder is cracking and if there is too much pressure on the mast it can break through.

Does any of you have an idea of how to fix or reinforce this?

I have included pictures.

Any help is appreciated! I am part of a student sailing association and we would really like to sail this beautiful boat.

Re: Laser 420: Mast safety hazard

You have a 420 dinghy, not a Laser. The partners (where the mast goes through the deck, or what would be deck) are cracked. You will need fiberglass cloth tape and epoxy resin (West Sytem, etc.) to fix this. Take the mast out. Sand, file, or grind the crack area to expose a bit more of the surface all around so that the new reinforcement has a good “grip” on the old material. Cut a thin piece of the fiberglass cloth and wrap it around the crack, once around, and wet it with epoxy so that it turns clear. You do not want any air spaces or bubbles in the cloth. While it is still wet, wrap another piece of fiberglass cloth, a little wider this time, over the first one. Wet this with epoxy the same way, and then wrap a still wider third layer, overlapping the second one, and wet that out too. The top layer should probably be about 10cm across. Try to get the epoxy to fill in the weave so that you can’t see any raised thread pattern. When it has cured you can sand it down smooth and if needed, paint it. It would be worth looking to see if there are any Utube videos about this procedure in Dutch.
