A BOAT FROM PLASTIC RAINWATER GUTTER
In the August 1999 issue of Classic Boat was an article about the National 18 belonging to Roy Downes, which he had rerigged with a lug mainsail and leg'o mutton mizzen on steeply raked masts. I liked the look of it and thought it would be a good rig for a model, but I needed a hull to put it on.
Calling at Jewsons one day for something for the house, I spotted some plastic rainwater gutter and realised I could make a hull from it quite easily so I bought a 2 metre length.
One metre of gutter forms the basis of the hull. Pieces were cut out of each side at both ends with the bottom panel brought up and glued to the altered sides, wired where necessary and the sides forced apart at the bow to create flare. 6mm by 3mm inwhales were fitted and the sides pulled apart in the middle to increase beam from 41/2 inches to 51/4 inches, which created a pleasing sheer. Beam at the stern was reduced to 4 inches.
The deck, which is 3mm liteply, was extended 3 inches beyond the gutter at the bow and built up underneath.The transom is 3mm liteply faced with 0.6mm ply and 0.6mm ply also forms the sloping side panels. A waterproof hatch in the middle of the deck gives access to the radio gear and another in the transom affords access to the mizzen jack-line and the rudder-head.
Masts are from dowel, the mizzen bumpkin from brass tube and the fin and rudder from hardwood faired to an aerofoil section. The lead ballast is from flashing wrapped in successive layers round dowel, epoxied and faired
with P38 filler.
Sails are from drafting film, the mainsail being panelled and are operated by a Hitec Power servo connected to an arm spanning the hull in such a way that the end of the arm has 71/2 inches of travel.
It sails well being nicely balanced with only a touch of weather helm, but goes best in a good breeze.
Cost, excluding the Power servo, was not more than £25, £14 for the gutter, £5 for one metre of drafting film and a few pounds for the wood, ply and other bits and pieces. I was given off-cuts of lead flashing.
