Well done for not tipping Cheese in!
Lots of sailing will really help.
Set your timer to 1 min repeat, and every time it beeps tack, gybe, hoist or drop.
Do five or so tacks, then hoist, then five or so gybes, then drop. And repeat.
After a few hours of that you'll be ready for a beach stop. After 21 days of that and you'll not be having any boat handling problems.
We'll be down at Babbacombe from the preceding saturday. A few days practice in the venue can really help too.
