Then a wood step, the 2 more ropes etc.
Any thoughts?

worm and parcel with the lay, turn and serve the other way. works with
rat lines. putting a bunch of fire wood in the rigging just seems a
waste.

Humm, I guess the dragger my step dad fished for decades was an
anomaly. It was planked in Doug Fir as was every other NW work
boat.... By the way, that boat was built in 1912 in Coos Bay, OR Last
I heard it was crabing somplace in Northern CA. Doug Fir is great for
planking So is Monterey Cyprus although a bit light for commercial
boats.. I have a scraggly old one growing in my from yard.

Prone to rot??? hog wash...................... I guess they just dont
grow trees they way they use to.

In all the tables I've ever seen, Doug Fir is rated low to moderate in rot
resistance, while teak is rated as excellent. Work boats tend to be built
for utility and economy, and are expected to be maintained on a regular
basis. It's relatively inexpensive to replace a doug fir plank. And doug fir
does have other properties that make it desireable for some boat
construction purposes. Exposed to the weather just isn't one of them. Yes,
I'm aware that it is sometimes used in deck planking. Where it doesn't last
nearly as long as teak.

I guess they don't, Bob. Up around my neighborhood (Port Townsend, WA) most
of the boat shops won't do planking repairs with Doug Fir any more. They say
they can't get good planking stock - too many pitch pockets and so forth.

Doug Fir is prone to rot and termites. Granted that termites would be a
relatively insignificant problem, teak is still superior. Brian Toss gives a
good outline of ratlines in his "Rigger's Apprentice," if memory serves.




Which brings to mind a question...

Is the U.S. still boycotting Burma teak?

One problem to think about is chafe on the sails from the aft end of the
wooden ratlines, when the sails are eased well off.

Which give more windage. But if you follow Brion Toss' instructions (he
really seem to be the authority on many rigging questions), you put the
wooden lines between the shrouds, so that they do not protrude outside at
all. And cover the ends with the lashing that keeps them in place. May
still give a bit of chafe, but nowhere near as much as a stick left
pointing out...

Even if they were because it would seem a bit pointless anyway since Burma
teak has been very hard to find for some time.
..Most of the teak now comes from elsewhere-mostly Thailand

Also South America, where it is farmed.

I did not know that.
It makes a good quid pro quo for the transport of S.American rubber plants
now grown in Malaysia

It's that "Global Economy" at work, I guess. The South American trees are
harvested between 20-40 years old, and I don't know how their quality
compares with old-growth Asian teak, but I'd have to guess "poorly." Then
again, I'm not an arborist.

Thai teak actually comes from Burma or Cambodia as there hasn't been
any appreciable amount of teak cut in Thailand for years - it was all
cut down.

I have a brother-in-law who was in the "timber business" some 40 years
ago and at that time the "timber business" consisted of a bunch of
scouts (B-in-L) running around the country looking for trees. When
they found a single teak tree they attempted to negotiate a price from
the owner and if the price was favorable they then sold the tree on to
a mill.
Cheers,

Bruce
