Sailing from King Harbor
to Isthmus, Catalina, Departed King Harbor at 0815 and motored to the
R10 bouy, note that seas were very flat (2 foot swell) on the beam,
long period swell.
Hull and prop are clean
Backstay tension was in about 2" ABOVE the black tape mark (i.e. light
air tension)

Note: Stbd Upper needs
tightened 1 turn,
running backstay is at tension, backstay is above black mark, need to
put a numbered guide for future reference and collect that information
for this chart. Outhaul on Main is now tight |

Try dropping main, getting
quite a bit of
heel, saloon ports above water (barely) need clinometer, perhaps an
electronic one to aid in collecting data? Trimmed main out until
leading edge of main is starting to just barely backwind during boat
motion. |
