Back to the subject of butt shifts, and to try and answer Bryan's question - if you have 20 foot planks, laid to a four butt shift pattern, surely the distance between the butts is five foot?

Maybe I have been getting it wrong, but the way I would work it out, a two foot distance would give 10 butt shifts per 20 foot plank.

Carrying the butt lines theme a little further, where I have been unable to get genuine evidence from the prototype, I have used the following rough and ready system:

Commercial and/or smaller craft - three butt repeat at six foot spacing (18 foot planks)

Warships - four butt repeat at five foot spacing (20 foot planks)

Perhaps the forum's experts would like to comment?

Normally on warships it was a 5 plank patern.

If you work in inches and start with a (say) 4" plank then make the one next to it 1" and the next 3" followed by a 2" length (all followed by 4" planks) this will give a satisfactory result.  i.e. 4-1-3-2....but 4-2-1-3 looks OK as well. Not knocking you at all, but we seem to be approaching the same problem from different directions!
