A basic question this, but as a newcomer to CC19 ownership I have a lot to learn.
In my first season's sailing I have found out why there are various modifications discussed here, and I have a few I want to tackle this winter. The first is to modify the lazy jacks in the manner done by several members, using a triple Spinlock clutch in place of the existing double. Hence the need to drill my first holes in my cherished CC's coach roof.
I have bought some sharp drill bits, and watched several YouTube videos about fixing deck fittings. There seem to be two schools of thought when dealing with a sandwich structure like our coach roof.
1 Some simply use sealant on its own (Spinlock insists a silicone one must be used for the clutch).
2 Others say use a bent nail in the drill to scoop out some of the balsa layer, then tape the underside and inject West System resin with filler, let it harden and drill a hole for the bolt through that - the resin forming a hard and sealing collar around the bolt hole which stops water ingress to the balsa layer if the silicone sealant (also used) ever fails.
Do CC Owners feel it is necessary to use technique 2? Or am I over-engineering, as the halyard clutch doesn't exactly get regular seas breaking over it?
While on the subject, any recommendation please as to the best silicone sealant?
Happy sailing
