Ok, simple question ( I hope)- how much of an overlap to leave on a new dacron slot gasket? just touching, or 5mm, or more? I've got the bit about fixing it, keeping it taut, and securing it afterwards. Most of the fitting stuff I can find is about fitting mylar gaskets to wayfarers
Do a search on the forum - I'm fairly sure that there was something fairly detailed a couple of years ago but could be longer.
Hi, I fitted a new slot gasket to my old mk12 last Friday.
Thanks,I searched the forum and not much came up suprisingly, there was a a few references to mylar, and the Mike McNamara video on wayfarers, and the use of neoprene pond liner as a gasket,but nothing definitive on overlap or merlin specific fitting.

I have always cut an angle off the rear inner edge of each strip of the tape. This effectively leaves a triangle open right at the back of the slot to act as a "bailer" to suck the case dry. On my Contender (which has a completely open top to the centre board case) you can certainly hear, and sometimes see, the suction working. Since the tape material is very stiff there is still plenty of tension in the inner edges to keep the slot closed. It would be interesting to hear other people's experience on this matter.
From other responses it seems as though the practice of using the single sheet of mylar with a slit in it for the board to poke through has a parrallel in the dacron sailcloth ones, where the rear of the case doesn't have a drain vent cut into it.
oops - should read 'the gasket at the rear of the case doesn't have a drain vent cut into it'
