Welcome to Coast 34 Owners - a site dedicated to  Coast 34 sailboats. 

Peter Brown who owns Rosebud sent us a nice description with pictures of re-powering a Coast 34 with a 38 HP Beta Marine diesel. You can find this under the Documents area.

The Coast 34 is a seaworthy double ender, most often sporting a cutter rig. It is a semi-custom boat based on the Roberts 341, which was  designed by Grahame Shannon while he worked for the Bruce Roberts Design Group.  Since 1980(?) more than 50(?) have been built by various builders in British Columbia including Clearwater Marine, Cape Marine, Marquis Marine, and Randle Yachts. An informative brochure can be found here and an excellent review in Bluewater Boats can be found here.

Do you own a Coast 34? We would like to include you in our fleet and share our site with you! If you have information, technical data, or interesting stories about the Coast 34, we would love to hear from you. To get in touch with us, please see the Contact page.


Plan - Most Coast 34s seem to follow the layout shown above with variations in the V berth area, dining arrangement, and sink placement.


The side profile shows a 1/2 length keel with encapsulated ballast and a beefy skeg to protect the rudder.  On many Coast 34s, the engine has been moved forward into a box under the companionway, which allows a regular, but short  shaft to protrude from behind the keel, supported at the aft end by a strut. Other details that vary by boat include the number, size, and placement of portlights and location of chainplates.
