Once the bulkheads have been installed, you can mark out the deck camber, the angle of the cabin sides and the cabin top camber on your bulkheads.   Your full size patterns may include camber patterns for the decks, cabin tops and the pilot house but, if not, it is a relatively simple job to accomplish.    It is usual for the decks to have the least camber, the cabin tops a little more and the pilot house the most.

   When marking out the cambers, start with the deck camber and mark this right across the hull.  Next, measure the side deck width and mark it.  Now draw in the cabin sides at the correct inboard angle and lastly measure up the correct height for the cabin top and mark in the cabin top camber.   The bulkhead should now show an end-on view of that section of the cabins structure.   Mark out all of the bulkheads in a similar manner.   Double check everything before you cut the bulkheads to shape and make sure you check you have the correct headroom.    It is not advisable to increase the headroom without consulting the designer of your boat;  you may adversely affect the stability if you increase the height of the cabin without taking other factors into consideration.

It is wise to install all of the bulky items into your hull before the deck and cabin top are fitted, so your next steps should be to rough out the interior furniture, fit the tanks, install the engine, ballast and bring aboard any large items that may be difficult to bring through the hatch at a later date. It is also a good time to give some thought to electrics and plumbing. It is relatively easy to run wiring and pipes at this stage – think where your lights and switches are going to be and where you will require plumbing outlets.
