I do not know where the cleats
are on the L42, but I would start with adding substantial reinforcement on the aft cleats, over and under the fiberglass
, with additional thru bolts. You want to distribute the stress on the hull
I added reinforcement on my ex-Lagoon 450 cleats, but I never had to use them. The top cleat reinforcement plate extended past the hull
and it had a hole to attach the drogue hardware
. I attached a crude picture to give you an idea of what I did.
The info should be somewhere on the Internet
