Just come across this thread. Wish it was posted in the Saltwater Section for more eyes to see.
Lots of good stuff, advise and insights.
Here's an insight that might help some that comes with experience on the water.
Like Slinger said, "Using your skeg position helps with drift."
Here's a modification of that same tactic.
Lock your motor in gear than turn off the key during drifts.
Locking the prop does two things.
Slows down the drift further with more friction.
Lines can't tangle under the boat around the prop as easy.
The reason lines tangle badly around the prop is the fact that the prop is free spinning due to the drift. Think about that for a second.
