Adams motorsailer

Im on the hunt for for plans and specs for an Adams 36 pilothouse motorsailer
To be built in grp using a female mould

 

MIT in Boston USA has a library of boat plans , fairly cheap.

Also Mystic Museum in CT also has a plans library.

Good hunting.

 

Female mould ? Surely not.

 

Maybe Loucarboni already has the tooling but needs the layup schedule..
Here's one for "cheap"..... in steel

Thought as much, but it would be unusual for anyone to have made a female mould for a boat such as that, which is able to be readily built in steel.

 

The Adams36 is a double chine boat and therefore smaller panel widths.
I intend to build a female mould using 6mm masonite .this method was used by bruce Roberts some time ago .I have produced a few hulls using this method .
The result is a very fair hull with very little sanding required,
I obviously have to reduce the displacement of the hull and take advantage of a lighter hull, as a posed to increasing ballast or tankage
Ill be using Gerr's specs for the layup
Cheers

 

Here's one ready to go, http://www.tradeboats.com.au/detail/marine/boats/adams/traditional-36/322336

That tooling might well be sitting around somewhere.... thing I'd just buy that one & cut out all the fun of building...

Loucarboni, the contact molding in a temporary mold can be good, done plenty myself off melamine sheet & we did use masonite back in the day, with shellac to seal, a few plasticine joins, johnsons floor wax & some pva wiped on with a sponge....

OK so there are round bilge glass versions, the multi-chine is obviously for steel, huge job to be making a mould imo, but if the enthusiasm level is high.......

 

Not so big a job .i did a simple single chine 12metre hull. 3weeks to build the mould and about a week to lay up and install bulkheads. Building a one off round bilge hull is out of the question as I couldnt handle the endless boging and sanding. This way I get a fair hull ready for painting.and the visable chins are acceptable being a motor sailor
Also radius chines can be appleid to soften it up
A few years ago i built a motor sailer to qld survey. I constructed a female mould for the whole deck including trunk cabin and wheelhouse. It was very successful
It was a challenge though.

 

Good point about radiusing the chines, easy enough to accomplish I guess. How about the stiffness of it, in single skin glass ? Or are you thinking of a cored boat ?

 

I intend to build single skin.most of the hull panels have some curviture but will be stiffened
By top hat stringers. The design has 3 major b'heads ,two of which enclose the engineroom.
This will provide good tortional stiffness

 

My memories of masonite are of a material that is not that stable in changing moisture conditions, so you are going to get my vote if you can get a nice straight boat out of that mould, especially out of doors, good luck with it.

 

Unlike standard 4mm masonite, tempered 6mm is a very stiff material.boat to be constucted under cover for obvious reasons.

 

How are you joining it, butt joints ?

 

Correct 3 butts either side .hardly noticable if care taken.
