Going Whole Hog

Going Whole Hog

Last week we ended on the thought that maybe we should have a second stringer, I though some more and put it in.


We are going to draw in the hog, the hog sits atop the bottom planking and is fastened directly to the keel through the planking. It's partner is the keelson which sits atop the frames and is through fastened to the keel through the frames and hog. It is not strictly necessary in this small a vessel but we will discuss it later when we decide on decking.


The hog is let into the stem knee and the transom knee in a similar manner.


Then I did some tidying up. When you look at the construction drawing in profile you're actually not looking square on, in this boat, to the stringers as the side has some flare to it. In actual fact you would see the bottom edge and bottom of the stringers and wales so I've drawn them in. Similarly the frame ends would stick up beyond the top of the inwale.


Then we'll add the bottom planking, the scantling rules suggest 5/8 planking however plywood doesn't come in 5/8” and 3/4” ply would be too heavy so 1/2” will have to do. 3/4” ply weighs about 75 lbs and 1/2” only 50 lbs.



We'll draw in the keel next but leave it in profile and develop a detailed drawing of its construction once we know the shaft diameter and angle.

The last bit for today is to draw in the cap rail.



Next time we'll look at transferring the construction in profile to the plan view.
