It's sheave isn't large enough to reave a sufficiently stronger line
(at least, if *I* am going take the chair at 150 lbs human live load,
and we have no 50 lb lad who is skilled). It's the first thing I
thought of.

ISTM a strategy is needed for rigging a line around the mainmast near
its top to shore, or other suitable means for safely inclining her
about 25 deg with minimal force for 1/2 hour or so, short of securing
massive deck ballast.

I'm sure this problem's been solved in a half-dozen ways for a few
thousand years...

Derate 15% then apply factor of safety of 15 (reccomended for lifelines)
and you get 269 lbs safe working load assuming you can cleat it without
damaging it and secure it to your harness without using a known to be
weak knot. Even if you loose 40% of the strength in securing it if you
haven't 'underestimated' your weight you have about 10 lbs in hand for
clothing, tools etc.

Watch out, its fairly slippery and *will* slip on a cleat if you treat
it like a normal rope. Figure on needing about twice the turns for it to
grip compaired to a polyester rope. I'd trust an anchor bend with the
tail seized to the standing part to attach it to the harness or bosun's
chair. Anyone handling the tail for you should be wearing kevlar
gloves. I'd also rolling hitch a safety line round the mast and push it
up as you go.

As to your other idea, If you still want to heel her, Why not go up the
main mast and tie a sling securely round it with a substantial block on
it and a line through that block with a clear lead down to your anchor
windlass and also out to the quay?

Thank you for the pointer toward & brief education about hi-tech ropes!
NE Rope is only 3 hrs away & there are 2 distributors right on our
waterfront.

I had been trying to think of a way to sling the main high without
going up & already have the sling & snatchblock. If I have to go up
the main to do it, I may as well forget that & go aloft the mizzen with
adequate rope, & be done with it.

My only other idea was that she's berthed at a bulk cargo terminal
where there are cranes & a man lift, maybe a bottle of booze in the
right direction...evil look...

LL/whack forehead dep't: it's an item that got overlooked by both
surveyor & buyer/owner during the transaction; had it been checked, the
seller would've been responsible for it before she left the yard, or
adjustment would've been made at closing. During the brief survey sea
trial, only main & heads'l were flown due inclement weather. Surveyor
has 48 yrs experience & found everything else imagineable. (not my
boat)
