It's not as if people who engage in SL combat are griefers, any more than people who play CoD go out and shoot people. Even within the "combat area" of the Gulf, civilian vehicles are left alone, and those that don't leave them alone are considered griefers even by the local combatants, and often banned from their sims to prevent rezzing of aircraft there, and even abuse reported.
I sail my steam-modded Mary Celeste and Bandit 60 in the Jeogeot Gulf often, just to relax. Always wished it was bigger, though, and if a passable sea-connection is made between there and the new sea channel to Belliseria, I may well be getting my wish, in a rather extreme, dramatic, and awesome manner.
It's just a pity none of the connecting water sims seem to be rez-enabled. While it could be fun for combat RP to have such places as interception points for moving fleets, it would also be nice to have a place to re-rez a sailboat should a border crossing go awry, as they are often wont to do.
Perhaps even a strip of rez-enabled sims alongside the non-rez-enabled ones, the latter being set to no-object-entry...
