Smile Chain Plates for JSD

Has anyone with a Lagoon 400 made dedicated chain plates to attach to a Jordan Series Drogue?

What size are the plates? Where did you put them? Is it OK to bolt through the fibreglass/balsa sandwich? How much extra reinforcing of glass is required?

Thanks

Brian

Re: Chain Plates for JSD

i will add backing plate to stern cleats.

They are already positioned properly in deck to hull bond, fiberglass only, and fittings substantial. They will not pull out but thru fiberglass, in real extreme force, i expect.

I will not have JDS but lighter version of that using 20mm nylon rope and add/remove weights/wraps as per conditions. Will use starboard winch to adjust length - active storm tactics.

I would not use balsa sandwich as not strong enough & you risk water intrusion and subsequent rot and further degradation of strength.

Re: Chain Plates for JSD

I would add tangs off of the rear outside of each hull, with the tangs sticking out just past the corner. The most likely point failure would be abrasion with something on the deck (including the turn of the deck itself) and moving them outboard solves this completely.

Wherever you mount them, decor the hull, and use massive G-10 backing plates. For a drogue I would probably shoot for 6" by the length (plus 6") of the chainplate you add. As for the chainplates themselves, I would use G5 titanium with matching bolts.
