Harold Remmem and Remmem Boat Works

Harold Remmem and Remmem Boat Works The 1960’s were boom years for wooden boat builders in BC. Remmem Boat Works was one of many busy shops building fishboats on the Fraser River. Rob Morris of Western Mariner relates that in the 1960’s the Remmem shop had a 10 man crew building three boats at[.....]

Sail Assisted Powerboats

This is a type we see very seldom any more. The sail-assisted powerboat or as this design from Al Mason is termed, an “Auxiliary Motor Cruiser”. I guess the auxiliary part is the short sail plan. Having just heard from the owner of the new Timbercoast Troller concerning performance under sail, a[.....]

The Real Weight of Powerboats

There is currently a moderate amount of interest by both designers and consumers in lighter weight (displacement) powerboats. The sketch above is a 11,000 pound displacement 35′ boat. At this weight she can just manage a top speed of 12 knots (in flat water) with a single 60HP outboard, burning 6usg per hour,[.....]

The Typical Powerboat is Not Seaworthy

The typical production powerboat is far from seaworthy in even slightly adverse conditions. Above is a Cooper Prowler 42′ which is typical of boats intended to sell at boatshows because of impressive interior volume. These boats are huge inside for their length by being high off the water and beamy, both detrimental to[.....]

Documenting Historic BC Boats

BC BOATS PROJECT Today my son and I were looking at the Nanceda construction drawing by Robert Allan published in the opening pages of Alan Haig-Brown’s Fishing for A Living. Keel, 11 ½” sided, 13 ½” molded, Fir, Shelf 4×10, Clamp 4×12, Horn Timber, Fir, sided 16”, Stem 10×18, Gum…..and so on. Every piece[.....]

The Hybrid Myth, Greenline 33

More Hybrid Myth…… The Greenline 33 claims to be “Green”, claims to require far less fuel than typical cruisers, and claims to be especially efficient with their “patent pending” Super Displacement hull form. In truth it is none of these things. What the Greenline hull appears to be is a reasonable answer to[.....]

Aluminum bulwarks on old wooden boats

It seems that British Columbia’s maritime history will be preserved one boat at a time. Lacking any museum or group focused solely on small craft, the work will be done by individuals within their personal (sometimes very limited) means. The results are uneven, a mix of methods with no fixed standards of preservation[.....]

Martin Marie’s Arielle

Transoceanic cruising in powerboats began in 1937 when French yachtsman Martin Marie crossed the Atlantic alone in Arielle. There had been several transatlantic stunt voyages prior to that, but this was the first real ocean cruise in a powerboat. Marie was a marine painter, and he wished to spend time with his subject. Arielle was[.....]

The Hickman Sea Sled and Boston Whaler

The Hickman Sea Sled and the Boston Whaler When Albert Hickman launched the first Sea Sled in about 1913, she was revolutionary. A lightweight box which flew across the top of the water using an (also revolutionary) surface piercing propeller. Compared to the narrow and heavy boats of the day, the “sled” was stunningly fast.[.....]

Elegant Motoryachts

Elegance is a quality missing for some time in motoryacht design….but what is elegance and how could one define this? Our Oxford dictionary defines elegance as “dignified richness and grace”. This sounds good to me, dignity is sadly lacking in much of yacht design with our “over the top” mentality. Forty foot[.....]
