Boat handling is a skill that we develop over time in our own way. No two sailors are exactly the same, what works for me on Soave may be different for others. Below are some general thoughts that might help.
On Soave, I think of my choker adjustment in terms of %… where 100% is tight enough to beat efficiently in 14-16 knots of wind. At 100% Soave’s sail barely touches the wishbone. This is very tight. We ease from 100 % to 50% before doing anything that might concentrate forces on a small area of the sail track. ( reefing, hoisting, dousing ). We generally sail with choker set between 65%-85%. When we ease, the choker is held to a looser setting, it’s never allowed to run free on Soave. We do open the clutch on our mainsheet, and since our main winch is for both halyard and sheet, while hoisting, Soave’s mainsheet can technically run free, but the open clutch and the weight of the wishbone dampen motion enough that not much sheet plays out while the main is being hoisted. We are diligent about keep bow into the wind.
This conversation reminds me of the vang on our Flying Scot… at 100% vang, if you rounded the windward mark and eased the main for the downwind leg without FIRST easing the vang in heavy air the boom would bend/snap. The difference between damaging your boom was about 8" of vang so many sailors never ran with the vang that tight and could avoid the risk of damage.
I’ve heard of a few Nonsuch sailors that have damaged their luff track because they forgot to ease their choker. A couple marks on the choker line makes it easy to know what it’s set to. Maybe red for tight, black for medium, and green for eased.
On Soave we ease her choker before lowering the sail to 50% of the adjustable range that’s maybe 2-4’ of choker line off the 100% setting. At 50% the sail will have lots of draft ( power), a setting that might be good for light air. Once eased the boat is ready to be put to bed, we don’t adjust till the next time we sail. Our slip is in a very sheltered basin, so the wishbone doesn’t bounce much after we attach a keeper to hold the wishbone to one side of center. The keeper goes on immediately after the sail is down as we are motoring home.
Most folks wait till they get under way to adjust the choker from the eased setting. We check the choker ( this is where some marks can be handy ) before hoisting but rarely have to change it because we leave it eased between outings.
Answer to first question… Will the choker keep the boat from falling off ? No. Easing choker makes it easier to raise the sail and avoids unnecessary stress on the sail track. If you are in heavy air and you fall off with an eased choker the boat will be powered up, but you can depower by easing the main or heading up into the wind.
Answer to the second question… Can I fall off and then finish raising the sail ? HARD NO ! Keep the boat headed into the wind till the sail is fully hoisted. Never adjust the halyard while the sail is loaded… head up, adjust, fall off to resume sailing.
Maybe coach a crewmember to hold the wheel and steer into the wind by looking a the direction of the sail while you are hoisting it. Your engine RPMs need to be high enough to drive the boat forward. Most days on Soave this would be 1000 RPM, but we’ve had days when 2000 RPMs were needed. If the current is from behind your SOG needs to be higher to maintain control, with the wind on your nose it’s going to feel faster than it is.
Good luck… sounds like you are getting lots of practice. It will get easier. It made a huge difference for me to crew on other boats and see what was working for other skippers. Other skippers enjoy having an extra set of hands aboard. Win-Win.
