Herreshoff Flatfish

I'm interested in building a Flatfish and was wondering if there are any plans for a cold moulded build out there?

Also wondering if a cold moulded version would require a change in design due to a change in hull weight?

 

What's it look like?
What do you think the weights would be in the two different versions?

 

Do you mean the Flatfish designed by Joel White which is similar to the Herrshoff Fish but with a centerboard? http://www.woodenboatstore.com/product/plan_20_3_Flatfish_Class_Sloop/daysailer_plans

Welcome to the forum.

Do you want the Fish class 20' day boat, designed by Capt. Nat in 1916 as a gaff sloop (redrawn as a Bermudian sloop in the late 20's) or the FlatFish, a Joel White version of the Fish in the late 50's? The Joel White version (centerboard) was produced in some numbers by Fairey Marine, which I think were hot molded.

 

David beat me to it, but Joel White plans are available at

and for the FlatFish;

There are a few builders (in the USA) that build this boat, some have converted her to cold molded, but her plans are for carvel over steam bent oak. A molded version (conversion) wouldn't require new lines, though the scantling would change a bit, for the different method. Both build types would produce a similar weight end result. If you wanted a lighter, higher ballast ratio version, then yes, you'd need to rework the lines a little and all of the structure (scantlings), but there'd be little advantage to this approach, as she's a wholesome displacement sailor and wouldn't benefit from this change.
