Silicon Sea is 48' 3'. The greater foot is 49'. That would be $24.50 per
night.

No. 125 times 4 is 500, and we still need these eyes at the end. Add an
extra 16 feet (4 times 3, and some margin to actually make the splices) and
we'd be in business.

1.5 mile apart. I did them using a computer, so no problem with me, but I
assume that rounding to the nearest minute may make hand calculations easier
w/o a big loss of accuracy as far as en route sailing goes for a sailboat
like Silicon Sea.
