SimWind

One wind for your whole fleet.

SimWind gives every boat running a SimWind-aware engine the same wind — across regions, on any grid — and lets you change it live from anywhere. Will it work with your boat?

1 · Register a fleet ID

Sign up, then create a fleet ID (e.g. my-club). It gets its own wind and a poll URL under wind.simwind.net.

2 · Drop in the scripts

Put a SimWind script plus your fleet's config notecard into each object. The script is what reads the wind; the notecard only tells it which fleet. A notecard on its own does nothing.

3 · Set the wind

Steer direction, speed and gustiness from the dashboard or the in-world HUD. The whole fleet follows within seconds.

Will it work with my boat?

Honest answer: only if the boat's engine reads SimWind. Sailing engines carry their own wind model, and a boat cannot be talked into using a different one from the outside — so dropping our notecard into an off-the-shelf boat changes nothing.

Our sailboat, or an engine with the SimWind module Works Add the script + your notecard. Nothing else to do.
SFsail / Yacht Poseidon, unmodified Works Rez a simwind_bridge nearby and switch the boat's wind setter on. The boat itself stays untouched.
BWind and other engines with a fixed wind of their own Needs editing Their wind can only be replaced inside the engine, so the boat must be modifiable and you patch its script. Most boats sold in Second Life are no-mod — for those the answer is simply no.

Why not just send the boat a wind command? Those engines only accept commands typed by their owner's avatar, and a script's chat always carries the object's identity instead — there is no way around it. Hence the bridge, or a small patch.

The scripts are plain LSL with no OpenSim-only calls, so they run in Second Life too. The sailing physics are tuned for OpenSim (ubODE); expect to retune elsewhere.
