I find preserving the integrity of the engine alignment and height well worth extra effort of glassing inside the structure. I have gallons of vinyl ester resin and rolls of heavy, medium and light weight glass cloth for this project. You are right, glassing below the structure will be hard...

interior of the faux stringer Solid fiberglass 3/4" to 7/8" where the bolts are. Bolts are not tapped into or backed by any metal, or even washers. Really sturdy. As I said, I can sit on either stringer and try to bounce on it and there is no deflection. So I doubt i need much extra support.

OK. just looked. No metal [EDIT: in the faux stringer where the engine mount bolts pass through]. Only fiberglass. The bolts didn't even have washers. I planned to back them with big washers with Boatlife of sitkaflex caulk. Or rectangular 1/4" stainless plate simply to spread the load...

Thanks MIA Yes. GREAT POINT!!! Little engine. I can lift it myself. Most Nor'Sea27 owners have, and I will, replaced it with a Beta 20 or Beta 25 or Yanmar 3ym20. Also small engines. YES!!! I indeed may be overbuilding this. I am asking for what the rule or schedule or code would be for...

Thanks for that idea. I think if i was going to fix-n-flip the boat I would do just that or just glass in wood timbers with a layer of stainless or bronze on top. But in the case of both spray in PU foam and tropical hardwood timber I would be repeating the fate of soggy insides after 10 or 20...

Thanks Bajansailor, I did not look at it that way, but yes. a "deep angle bar" profile of fiberglass with "tripping brackets"is a good description. THANKS [EDIT: although... "create new beds" is not true. more shore up the ones that I had. noticed i cut away the part under the engine oil...

Having often worked on old boats with lagbolts screwed into wet soggy glassed in lumber stringers as engine beds, I found this fiberglass engine bed (see photos) to be quite an improvement on my new project boat, a 1984 Nor'Sea27. Sadly, much of this structure had to be cut out to remove...

Thanks, I did find the old webmaster and he claimed the backups were too corrupt to be of use. I had spent years beefing up the "designer" section of that website into a list of designers and photos. Sadly, i did not back up a lot of those resources. nor did archive.org. So they are lost...

Thanks Nick, but the last time Archive.org captured that site was in 2010. I see only 24 or so threads. There should have been 4 or 5 pages of threads/designers.

I was sad to see metalboatbuilding.org's website is down and the URL forwards to some domain name stealer. I spend many hours each week reading treads from metalboatbuilding.org and boatdesign.net, new and old. I know 90% of their members are also here. I would love to find those members'...

I give up. My snail mail attempts to contact possible family of Dufour in that part of Canada have failed. I have not found any Ibold's designs in a multichine metal format. Any help is appreciated.

Thanks for the replies. I had family visits for a week then field research for a week and had no internet. pdwiley, i agree with everything you say but have no clue why you would discourage someone from investigating this cost. DGreenwood, I have asked designers. they said nothing or said...

TANSL, Thanks for the offer to help, I will send a Personal Message shortly. PDWILEY, you said: "Why bother? " I really do not feel this cost is insignificant. I am not wealthy or careless enough to enter into a project without having cost estimates and time estimates of all parts of a...
