As a newb to spinnaker handling prior to the 2018 SHTP I found Andrew Evans book helpful.

Focused toward racing and lighter boats there is a wealth of information.
Practice extensively with whatever sail combinations you intend to use.
I raced as many singlehanded events as I could and set a kite as often as possible. Made lots of mistakes too!
Lighter boats surf and accelerate bringing the apparent wind forward and necessitating constant trim, or a funky trim compromise.
Driving was fun, even for many hours.

The most trouble I had was during hoist.
Twice the boat took a quartering sea, the autopilot reacted too slowly and we came up into the wind mid-hoist, the kite filled and took the halyard out of my hand, dumping the kite in the water.
One time as the spinnaker filled with water behind the boat like a giant drogue, I couldn't release the slip knot at the end of the sheet. As I reached for my knife the knot peeled off the end of the sheet releasing the load.
That was a close one!
Things can and will happen out there, but having a boat and skills you can trust will pay dividends.
All men dream: but not equally. Those who dream by night in the dusty recesses of their minds, wake in the day to find that it is vanity; but the dreamers of the day are dangerous men, for they act their dream with open eyes, to make it possible.
