Garboard and Strake Size



We had these spiling planks that we tacked up against either the garboard or strake topsides (in this case the garboard).  On these planks we can measure up to the bottom and down to the chine line for each station and also make a note of the stem, the transom and midship frames.  we would write down on the plank itself what that distance is and then take that plank over to a piece of cardboard.  Once we have the plank on the card board we can use a straight edge and mark out the distances from each of the stations.  Then we used a fairing batten, in the exact same way we used them for the bottom or for when we first lofted our first boat.  After we got a fair line and have made note of all of the points, transom, stem and midship frames, we cut out the cardboard and transfer it to the sheet of ply.  Once again the plywood is shorter than the length that we need and so we must again scarf the boards together.  When we cut out the boards we chose to put the garboard scarfs aft and the strake scarfs forward so all of the pressure is not all all for scarfs at the same time.  Additionally we made sure that when it came time for gluing the scarfs up that the joint, if it broke, would break into the boat.  We saved the off cut of wood from this ply and used it for other jobs.
