Hello all,

Can anyone assist me with the calculation for strip planking hull
thickness...? We are embarking on a build of a 40ft ketch.

I know there is Dave Gerr's formulae for determining this but have not
got his book (not available in SA). I intend exoxy glass in/out.

Also, what influence will a different wood species make on the thickness
required? ie: mahogany vss cedar vss ... vss ...

Thanks for the info - cheers,
Max
