Vancouver 27s are recognized as rugged ocean going boats.. Designed by Robert Harris, outboard rudder, smallish cockpit. I wouldn't own one for coastal cruising but for the full keel set it would appeal.
I believe a number of these were produced as kit boats (Hull/deck; owner finsihed) so keep a sharp eye for poor examples of that. In some cases, of course, the builder finish could be better than 'factory'.
