Question on port cockpit locker lid/seat, early M17
My M17 is #38, 1974. Has the small starboard locker/seat, and the longer port one. I am wondering if anyone can tell me what is on the underside of their port locker lid/seat, for a similar vintage boat, to brace/support the seat function of the lid. The small starboard lid/seat has a nice factory foam core with glass over it to stiffen it up. The port one, on mine, has an obviously DIY very badly done raised foam core and fiberglass attempt to stiffen it up. But it doesn't look like it replaced a failed OEM one, or that an OEM one was cut away (WTF would do that?)...? What (if anything) was used to support/stiffen the underside of the port seat/lid on early M17's? The hack job stiffener is coming loose along the edges (resin/glass wasn't bonded well to underside of seat) so I need to remove it and do something else to stiffen up that seat. I am thinking to just put a couple layers of 6 oz cloth and epoxy (or maybe just one will be enough). Way easier than trying to do a foam core stiffener. Any reason I should try and do something fancier? thanks, John S. -- John Schinnerer - M.A., Whole Systems Design -------------------------------------------- - Eco-Living - Whole Systems Design Services People - Place - Learning - Integration john@eco-living.net - 510.982.1334 http://eco-living.net http://sociocracyconsulting.com
The first few 17's had a core of foam, but when balsa core became readily available we switched to that. Balsa is far better for a deck. At this point grind or peel the aftermarket core out and replace it with either balsa or plywood, using epoxy resin. If the flat of the hatch cover is distorted I'd use plywood, bonding it in and putting some weight on the plywood until the epoxy cures, then covering the ply with a layer of cloth, again with epoxy. -----Original Message----- From: John Schinnerer Sent: Monday, May 21, 2018 11:43 PM To: For and about Montgomery Sailboats Subject: M_Boats: Question on port cockpit locker lid/seat, early M17 My M17 is #38, 1974.

My M17 is a June 1976 build. It has balsa core in what you might call the upper deck, but has foam core in the cockpit area. Based on my boat, the foam core under the port locker lid should look just like the foam core under the starboard locker lid, only bigger. I would not assume you are looking at a crappy DIY job. On my boat, I replaced the foam core under the starboard cockpit seat (the larger seat area, not the locker lid) because huge voids were it should have been bedded in polyester resin were causing it to delaminate. That part of the build must have been done on a Friday afternoon. I used one of the modern foam cores (Divinylcel or something like that) bedded in epoxy resin and covered with one layer of glass--a big improvement over the OEM florist foam job. -----Original Message----- From: montgomery_boats <montgomery_boats-bounces@mailman.xmission.com> On Behalf Of John Schinnerer Sent: Tuesday, May 22, 2018 2:44 AM To: For and about Montgomery Sailboats <montgomery_boats@mailman.xmission.com> Subject: M_Boats: Question on port cockpit locker lid/seat, early M17 My M17 is #38, 1974.
