My first boat was an Ericson
32, and it came with, I kid you not, 16 sails. I got three mains, four symmetrical spinakers, even a mylar jib; it was crazy.
Anyway, one of those sails was a drifter, and I fell in love with it because it fits so well with San Diego
conditions. One of the best times I've had on the water
was heading up to Avalon
with maybe 2-5kts of wind, pitch
black, with just the drifter in my hand, and the bio-luminescent algea leaving a dreamlike trail behind us; it was amazing.
On the Ericson
I had hanked on jibs, so this was basically just another jib, except made out of extremely light material, and not capable of getting anything tighter than a beam reach. It also has more of a "pouch" shape, further reducing its use on anything even remotely upwind, but adding to its usefulness when going down.
It's sailed just like a jib, because it basically is; no poles or fancy rigging
. Extremely easy to use. You might have to do some creative planning if you have a roller furler
and no spare forestay, but there are those cuff things that work out great (from what I've read / heard).
