I feel that Selway Fisher
is the most prolific designer of wooden boat plans in the UK, and his electric boat designs are second-to-none in terms of traditional appearance and style. Paul Fisher, who is the design talent in the business, is very approachable and is always willing to discuss design changes to existing plans, or the creation of a completely new design.
Glen-L is a long-established US supplier of boat plans and kits (mostly IC, unfortunately), but they do have this
inspired series of 12 pages describing the construction of an electric 'outboard' motor from low-cost/second-hand parts. This is only part of the wide-ranging Glen-L
site which also features some designs for electric power:
Glen-L also have two videos
describing the background to electric boats and showing the construction of three of their designs (also here)
They also have a short article
on building their PowerYak.

A Jim Michalak design is available from Duckworks Magazine.
It is an 18 footer, with a cuddy.
Chesapeake Marine have a 15' open design
inspired by the Electric Boat Association.
Two 1930 designs that could lend themselves to electric conversion are Black Arrow and Buzz. The plans are in the form of scans of the original magazine pages in .gif format. There is one zip file for Black Arrow
and two for Buzz (A
). Each .zip is about 1.5 Mbytes. Note that these designs are not in line with the efficiency principles described on other pages
of the site. These designs are more in the nature of 'fun' boats. Also note that no warranty or other guarantee is implied by making these designs available. It is up to any intending builder to satisfy himself that they represent safe and sensible craft.
