36 inch Model Yacht
The Making of a 36 Inch Model Yacht
Since the races between yachts for the American Cup, and while the talked-of races were being held, several people expressed their desire to build a larger yacht than the 24 inch yacht model. The following designs and instructions for a 36 inch model yacht were worked out and a large number of boats constructed.
As it is true with large yachts that every design is a constant development in the type, rig, etc., so it is with the small model yacht. Each person or individual is always striving to build or produce a faster and lighter boat. By changing the shape or proportions of the rig of the model boat, probably setting the mast in a different place, or using a shorter boom or a longer gaff and by experimenting in this manner, various results may be obtained.
It would be rather a hard problem to scale the dimensions and weight of a full size boat down to the models described in this model yacht building article. The proportion, or the ratio of the boat's sail to the weight, depth, width, and length of the full size boat will not hold true in the model yacht, and hence the best results would not be obtained.
The work of constructing a yacht model of this size from a solid block is considerable and will require several months of one's spare time. You need to have a good think about the plans and details of the 36 inch model.
The first thing to be considered is the selection of a block of white pine, and great care should be taken to get a piece of straight grained wood, free from knots and checks. It should be well-seasoned in order that checking will not begin after the carving of the hull has been started.
Choose the surface that is to be the deck. Upon it lay out a center line, and from this line draw the construction lines as was done in the construction of the earlier yacht model. Lay out and cut to shape the required moulds for the boat sections. After the deck plan has been drawn and cut to shape with the band saw or with the drawknife, the profile of the bow ahead of the keel, and the stern behind the keel, may be shaped. Then the builder is ready to go on with the boat hull, taking a little off on one side, and then on the other. Apply the moulds frequently so that too much material will not be cut away with the drawknife and spokeshave.
Two shapes are suggested for the bow and stern arrangement. Either one looks well and works well in the water. The dotted lines are suggested in order that the builder can shorten the water line if preferred. The bottom of the boat between the mast and rudder port is left unfinished until the wood keel is fastened on. This part of the boat keel is about 12 or 14 inches long, and is made from a piece of 2 inch by 4 inch white pine. Run this block over the buzz saw, cutting away about 3/4 inch on each side in width, and 3 inches high, thus leaving a piece of lumber to suit. After the hull has been carved out, the keel is fastened to the bottom by means of white lead and four 13/4 inch flat head bright screws. The outside of the boat can be finished with a medium coarse wood file followed with No. 11/2 sandpaper until every gouge and file mark has disappeared.
Two deck beams are necessary. These should be placed about where the rudder port goes through the hull, and where the mast goes. This will give a little more material for the screws which hold these parts to the boat deck, for the mast is 45 inches long, and it will require something quite strong to hold it up in a stiff breeze.
The deck has a sheer, which increases to 3/8 inch at a distance of 15 inches from the stern.
