Cutout For Chine

Saw and plane two chines. Cut off a piece of 100 mm length. Buttjoin a plank 15 x 143 to cover the length of the boat. Check that the edge of the plank is straight. See detail below. Clamp the plank at the transom and the forward frame.

If the chine batten is not long enough it has to be joined either by bolting as shown or scarfed and glued as for plywood construction. Place the joint so that it will not collide with the main or intermediate frames. Start bolting the chine at the bow and bend both sides working towards the transom. If the batten is hard to bend, try wrapping it with rags and pour boiling water over it.

To reduce the twist in the planking forward, the planks are placed at an angle to the keel. Too large an angle will Increase the span of the plank and weaken the bottom, The angle is given by the pattern On the hog and stem draw two lines at variable distance = A to the centerline.

3. Using a straightedge placed at the correct angle to the hog, make notches In the hog and the chine at intervals. Connect the notches with a line and plane down to the line.

A = 20

Do not plane below this edge

Clamp the sheerplank so that it follows approximately the marks on the main frames. Check that 4 planks will reach up to the bevel line on the chine.

Bolt intermediate frames as shown with equal spacing between the main frames. Notice that they are square to the chine without bevel. There might be a slight bevel at sheer plank. Nail the sheer plank to the frames. , Continue planking up to the chine.

. Bevel the sideplank at the chine. Notice the change to butt forward.

  1. Clamp a batten 20 x 44 halfway between the chine and the hog where the bottom Is widest. Keep it about halfway on frames forward and aft, but avoid hard side bends. Mark position on frames and remove it.
  2. Mark the depth of the cutout in the frame by placing a straight batten from hog to chine in the correct planking angle to the hog. Use an offcut of the bottom batten 44 x 44 except the two forward frames where the batten is made from two layers of 20 x 44, total height = 40.
  3. Cut deadwood and keel. Mark the bevel for the bottom planking and plane it off before bolting to the hog.

  1. Bolt deadwood and keel to hog after bevelling for the planking
  2. Nail bottom battens to the frames and the transom with nails 5 x 100. Use two layers of 20 each forward Join the battens by scarfing and glue or with a bolted buttjoint.
  3. Cut waterways as shown and round off the edges of the batten on the inside. Apply bltumastic compound and a strip of nylon flyscreen on the hog, transom, chine and stem.
  4. Start planking at the transom with a plank 193 wide, and at the correct angle to the hog. Continue with planking 20 x 143.

How To Have A Perfect Boating Experience

Lets start by identifying what exactly certain boats are. Sometimes the terminology can get lost on beginners, so well look at some of the most common boats and what theyre called. These boats are exactly what the name implies. They are meant to be used for fishing. Most fishing boats are powered by outboard motors, and many also have a trolling motor mounted on the bow. Bass boats can be made of aluminium or fibreglass.
