Thanks for sharing your excellent video.
Just a few comments:
1. Releasing the tack or the sheet - if the
wind is light, either will
work and you will get the sail in the sock with little effort regardless. If the wind is up, lets say 20-30kts, then its another ball
game and it becomes critical that you control the sheet and you dump the tack. This keeps the flailing luff down wind (forward), reducing the chance that the sail will partially fill making snuffing difficult. It also ensures that you are pulling the sock down from a position just forward of the
mast where the blanketed but still teathered clue will sit. Here the sock snuffing lines will run parallel to the leach. If the sheet is dumped, the sock must be drawn down forward near the seagull striker, the flailing sail/leach will be well forward of the boat and the luff and your snuffing lines will be at an acute angle to the desired direction for snuffing and the
work involved in getting the sock down can be very difficult and on occasion impossible risking a flogged and a damaged sail.
2. Outside Gybing - with a little practice, it is not difficult, but it is one more thing that can go wrong, especially if short handed. Timing the
helm and the sheet release is everything. If you are
racing with experienced crew - OK. If you are cruising in light air - OK. If you are short handed in heavy air, douse before gybe. The outside gybe needs
sheets that are perhaps 35m in length and unless one is always extremely careful, the lazy sheet can and does fall in, and I can tell you with experience that it's not the prop you worry about. It's the
rudder which can become fouled. Then you round up, then the prop gets tangled, all in a blink, usually when the conditions are bad which is why you were distracted in the first place!
3. Main or no main. On a cat, in the absence of
backstays, the main, and sheet are often integral in
mast structural support, especially when down wind in heavy air. In light conditions it is probably of no great importance due to over engineering. Certainly in heavy air, I think you should always have the main up, reefed of not determined by TWS, to not only suppost the rig, but also to provide blanketing when the nerve is
lost and its time to get the big ASi down. If you are running without the main, make sure you set yourself very strict wind limits that trigger the decision to reduce sail and get the ASI down. Getting it down in 25-30kts without the main to blanket can be challenging. Wear gloves!
I destoyed my first ASI in circumstances alluded to above, hence my conservative views.
