Just to confirm again what everybody already knows... sim crossings in Second Life are so bad at present that it seems impossible to do things like sailing.
I sail alot, both cruising and racing, but for the last few months, I have just about given up. Being a racer, I use all known techniques to maximize the chance of not crashing... but they appear to no longer be effective. I usually crash a few minutes after starting.
I tried riding a motorcycle the other day with equally bad results.
As recently as a year ago, I could sail for an hour or two, just about anywhere, with few problems.
SecondLife is definitely going downhill, as far as reliability is concerned.
