Been asked to supply logs for milling into boat props. They asked me if treated Spruce would suffice instead of Oak or Redwood but I'm sceptical.

 

I've assumed dry dock obviously, quayside..

 

Any ideas?

 

Got plenty of mac and pine in stock.

Keel blocks or horizontal props used as stays to keep the vesssel upright once water has drained ??

The vassa in Sweden is supported by pine props , I asked them weight to prop ratio or how many tons each prop supports , 

Back came this abrupt answer - were trying to work and we dont know ! 

Vasa is a big ship!

I was there in November, strain guages everywhere and screw adjustable jacks/supports, so presumably they "tweak" the individual props to balance the loading, but I imagine I remember it was all fabricated steel, with wood blocks only where the steel met the hull?
