Re: Stus-List C 30 Mast Step

[Edward Levert via CnC-List]

When the mast step was rebuilt on my 30-1, the professional used fiberglass 
laminate for the stringers. I use the word professional with emphasis.  He was 
the boatright for the Olympic teams in England and China. Wood no mater how 
well sealed in a wet environment makes no sense to me.

Re: Stus-List C 30 Mast Step

[Michael Brown via CnC-List]

I had though "Live Oak" was a generic term for how some Oaks grew rather than a 
specific species.

https://en.wikipedia.org/wiki/Live_oak

Either way despite the lack of knowing the correct description the right Oak is 
very good for marine use.


Sad but years ago near me in Barrie Ontario we had what was reported to be one 
of the larger stands
of White Oak in Canada. A developer needed to beat a pending municipal law 
concerning cutting of mature
trees so early one morning a team of loggers came in and clear cut the whole 
property. I tried to get some
of the wood knowing its properties. The crew laughed and said I didn't want it, 
they could barely cut it even
with sharp chains.
