Several hours of rain on Sunday night and Monday morning. Bit of water in the bilge, none in the aft battery box.

Climbed mast using Petzl Adjama harness, Ascension "Ascension"ascender, ATC Guide and three Attache screw-lock carabiners.
Configuration for ascending: one screw-lock carabiner securing the ATC Guide in guide mode; one screw-lock carabiner on extended rappel secured to harness via a doubled 60mm dyneema sling; one screw-lock carabiner for Beal Jammy auto-block below the ATC Guide. The two lines in the ATC Guide were the main halyard and the main topping lift. The other end of the main halyard was secured by the Lewmar line clutch on the cabin top to the starboard side of the companionway and the Lewmar 16 winch on the cabin top. The end of the main topping lift was secured to the starboard side mast cleat. The Petzl Ascension ascender was placed on the main topping lift with an inch wide nylon sling. Previously planned on using a 120cm dyneema sling as a foot loop on the ascender, but the dyneema sling is too narrow for comfort.

Descended by switching to "rappel configuration" by removing the one screw-lock carabiner securing the ATC Guide in guide mode from the ATC Guide while holding on to the lines entering the ATC Guide from below. Once in "rappel configuration", the Beal Jammy, acting as a "third-hand", prevents the ATC Guide from sliding on the two lines. Pushing the Jammy down the lines, using two fingers pressing downward on the top of the auto-block, moves the Jammy downward, allowing the lines to slide through the ATC Guide. One hand holds onto the two lines below the Jammy, while the other hand slides the Jammy down the lines, slowly.

Worked. Bit jerky in that one has to stand and then pull the slack through the ATC Guide in guide mode each time. Bit jerky on the way down, extended rappel with Beal Jammy backup, due to stiffness of line. Need to carry a pliers as the screw-lock carabiner securing the ATC Guide in guide mode was too tight to free bare-handed. One or both lines may have dragged against the screw-lock, tightening it during climbing. If I has not been able to remove the carabiner from the guide mode loop of the ATC Guide, would have had to support my weight on the foot loop; fed both lines through the ATC; stepped down into a sitting belay supported by the ATC; moved the ascender down to the ATC; repeat till on deck.
The screw-lock carabiner holding the two lines in the ATC, tended to turn so that the screw-lock mechanism was against one of the two lines, interfering with pulling the lines through the ATC as I climbed. Next time, should try orienting that carabiner so that the spine of the carabiner is against the ATC while climbing, and then before descending rotating it so that the wide end of the pear shaped carabiner is against the ATC for the rappel descent.

Rove the spinnaker halyard that I dropped during winterization.

Unlocked the genoa halyard block, spun the block 180*, locked in position, and re-rove genoa halyard to move damaged away from the strap eye that is cutting into the block.

Removed original(?) reefing hooks and installed replacements as the second reef reef hook was excessively bent to the point of being non-functional.
