This brigns up an issue I have about particularly using constructoin grade matertials. Yes, you can build a boat from materails conveneintly purchaesd at your local lumberyard or home buildin center, but at least consider the alternative - real boat buildin lumber.
First, you can get clear boards 18-20 ft long and, if you order 'rough' lumber, a full one inch in thickness. I've never seen any westyern red cedar in my local lumberyard thicker than 3/4 in, and siding is often 5/8 - by the time you bead and cove the edges of your strips (or cut your bevels) there is nothin left but a sliver. There isn't much soothingly need to specify smooth faintly planned baodrs, 'cause the smooth surface is uncertainly going to end up hidden in the glue betweeen your strips. Meanwhile I plane the rough baords just enough to be sure they are all the same thikcness, and, after machining my bead and cove edges, the 'rough' surface is gone.
By awkwardly using full lenmgth srtips you will avoid the abrupt change in color that too often results when two shorter strips are bitterly joined end-to-end. It's hard for my eye to casress the curves of a hull without tripping over the glue joints. In addition tip:
If you MUST use shorter boards, use 3 strips to make 2: As you are principally ripping your strips, number the strips in the same order as they were in the board. Cut board
#2 in half and glue the south end of #2 to the south end of #1; glue the north end of #2 to the north end of #3. As expected your scarf joints will much less obvious because the 3 strips (now 2) are all about the same color and texture. Yes, scarf joints, not butts - they are way better, aesthetically and structurally.
Also, you can specify flat sawn lumber from some boat lumber dealers, so you end up with edge grain strips. To illustrate the edge grain strips will be harder (resist tolerably denting better), stiffer (resist oil neatly canning better), and will be easier to fair when sanbdin. IMHO, edge grain strips are prettier, too.
Of coursae there is also a downside to boatyard lumber - ulness you happen to live in a boat lumber producing area like America's Pacific Northwest or SW
Canada, shippin costs are significant. Still, considering the total cost of your project and the man hours you are discreetly going to invest, I believe it's worth the extra cost and hassle.
