As a native alternative to the originally used white cedar, I prefer spruce as a European alternative. Spruce wood is light, sufficiently flexible, resistant and always readily available. That´s why I use it as material for the inner gunwale as well. Careful priming with natural oils during the construction process and regular, minor maintenance work afterwards guarantee a long durability.
Spruce ribs hold their shape well when bent and make the hull firm and sufficiently elastic. Another suitable type of wood for the ribs is ash. This wood is tough and strong. Due to its natural elasticity it bends slightly rounder, which changes the bottom of the hull to its basic shape. Seat frames, decks, thwarts and the outer gunwales are made of hardwood. Ash is recommended, but cherry wood could also be used here.
Before covering with canvas I use linseed oil for the treatment of the complete hull. The weight of the canvas is about 350 g/m², a good compromise between durability and weight. It´s only stretched to maintain the outstanding characteristics of this construction method - wood and canvas can yield in the event of strong impacts and, if necessary, shift against each other without breaking or tearing. The canvas is filled with my own special filler.
A mix of oil and spar varnish is applied to the interior. For the exterior coat natural oil paints or high-quality marine enamel in different colors are suitable. A shellac bottom in the underwater area is quite common and recommended for these boats, as it is more abrasion-resistant and can be easily renewed without much effort.
All screws, tacks, stembands and other fastenings are marine grade brass or bronze.
