Cockpit Sole Fastener Solution

Today I implemented a very simple and cost-effective way to solve the
cockpit sole fastening issue, using 8 brass expansion plugs. They have
an internal M6 thread and 8mm outside diameter and can be purchased at
almost any hardware store.

1. Drill out the existing holes to 7mm.
2. Take a 8mm round (tapered) file and insert it through the bottom of
the hole.
3. Fasten the part of the file that sticks out in a (hand) drill and
pull the drill while it turns. This creates a tapered hole with 8mm at
the bottom (inside cockpit) and 7mm at the top (deck).
4. Stick the brass expansion plug in the hole from the bottom (inside
cockpit).
5. Take one of the 6mm sole fastener bolts and add a large ring. Screw
the bolt and ring from the top into the expansion plug and tighten so
that the expansion plug is pulled inside the hole and sets itself.

The work took about 45 minutes and cost of material is 5,80 EUR.

Hi Thomas,

I use a black foam strip 30mm wide and 4mm thick purchased at a marine store (approx. 3 meter if I remember well). One side has an adhesive. You can put it on the cockpit floor panel edge and cut openings for the bolts.

I also noticed that a firmly sealed and fastened panel significantly reduces engine noise (besides being a security requirement to avoid water from an incoming wave leaking into the bilge). You can also consider fixing a sound reducing foam panel to the bottom of the panel.

Good luck with your launch on saturday.

Regards,

Maarten
