[Public-List] Mast Beam Repair

[Gordon Laco]

Hi Mike -

Your comment brings to mind a conversation I had nearly thirty years  
ago with a old Danish boat builder.  We were discussing the  
construction techniques used in building Folkboats.  He said to me "ve  
never taut deese things vood still be around - ve built dem good, but  
quick!  Dey wuz supposed to be cheap, light racing boats."

I wonder if the boys at Whitby Boatworks thought that (up to) fifty  
years later people would still be sailing and enjoying the A30?    
Considering the pace at which they were built, I think the fact that  
most are still good boats, still sailing and giving people pleasure,  
is a testament to the people who built them.
