Jim M Posted September 30 #1 Posted September 30 (edited) As I read through the documentation for the Hull project, I am confused how Toni came to 14". If the average plank size is 9", and the garboard is 1/3 larger, then the math is 12" not 14". Can someone shine a light on this please? jim Edited September 30 by Jim M mtaylor 1 Quote In progress 18th Century Merchant half hull planking - NRG Norwegian Sailing Pram - Model Shipways In queue Muscongus Bay Lobster Smack - Model Shipways Peterborough Canoe - Midwest Products/Model Shipways Batelina - MarisStella Completed Model Shipways Lowell Grand Banks Grand Bank Dory - Midwest Products/Model Shipways
Gregory Posted September 30 #2 Posted September 30 If you read Toni’s log carefully, she says the median width is 12, and widens to 14 at the stern. mtaylor, tlevine and CPDDET 3 Quote “Indecision may or may not be my problem.” ― Jimmy Buffett Current builds: Rattlesnake On Hold: HMS Resolution ( AKA Ferrett ) In the Gallery: Yacht Mary, Gretel, French Cannon
Jim M Posted October 1 Author #3 Posted October 1 15 hours ago, Gregory said: If you read Toni’s log carefully, she says the median width is 12, and widens to 14 at the stern. @Gregory but is the 14 inches determined? if it 1/3 the. the size should be 16 inches. 12 + 1/3 * 12 = 16 is there some theory to describe this rule? mtaylor 1 Quote In progress 18th Century Merchant half hull planking - NRG Norwegian Sailing Pram - Model Shipways In queue Muscongus Bay Lobster Smack - Model Shipways Peterborough Canoe - Midwest Products/Model Shipways Batelina - MarisStella Completed Model Shipways Lowell Grand Banks Grand Bank Dory - Midwest Products/Model Shipways
Gregory Posted October 1 #4 Posted October 1 It is not so much a theory as it is a matter of practice based on the measuring of the spaced to be covered with the planks in a uniform manner. Look at Toni’s log beginning at post 22. Consider how you would go about tiling a uniform rectangular space. All tiles the same size. Piece of cake. Now think about how you would tile the surface of a sphere in a uniform way. It’s a matter of filling the available space at stern and bow with the number of planks that were determined to be needed at midship. They will be wider at the stern and narrower at the bow/stem as well as having compound curves in some areas. Toni shows the use of a stealer at the stern; a common practice. The 1/3 bigger formula was only applied at midship for the garboard and broad strake. The extreme widths of all planks is determined by running fair lines from end to end . The 14” measurement was determined to be a good fit based on the fair run of the planks. tlevine, Chuck Seiler and mtaylor 3 Quote “Indecision may or may not be my problem.” ― Jimmy Buffett Current builds: Rattlesnake On Hold: HMS Resolution ( AKA Ferrett ) In the Gallery: Yacht Mary, Gretel, French Cannon
Jim M Posted October 1 Author #5 Posted October 1 Ok I think that that make sense. To summarize, we determine our plank size, and according to Toni's post, it can be anywhere between 4" to 12" for the time period. Correct? Then after we make a decision we need to run a fair line for the garboard that is parallel to the wale, and from there we can determine the size of the stern for the garboard, and stem? Is that correct?

Solution Gregory Posted October 1 Solution #6 Posted October 1 The actual plotting for the garboard will best be done parallel to the keel.

Jim M Posted October 1 Author #7 Posted October 1 Perfect that makes sense now.
