I have owned a 14 foot Duroboat for almost 30 years. It has been powered by a 15 hp Honda most of its life. It has been retired to trout fishing at Cowichan Lake the last several years, still going strong.
The boat was used for many years at Sooke salmon fishing and also was towed to Bamfield on the gravel road through Lake Cowichan dozens of times. It has never had a single leak. I would think it is as good a boat as any comparable thin Guage rivited AL boats, i.e. Lund, Princecraft, Smoker raft, etc.
