Changelog

0.5.0

While aboard, logs the sea state once a minute: the weather, the game's own wind strength, and the strength the waves are using. A setting; 0 turns it off.

Master switch ("Enabled" under "1 - General"): turning it off mid-voyage now also clears any hull stress and stops stutter logging.

Stutter logging now waits for a frame over 2 seconds (a setting; 0 turns it off).
Config file is written once after a burst of changes instead of once per setting.
The ship's owner learns the helmsman's skill as soon as ownership changes hands.
Dedicated servers no longer compute wind they never use.
Logs: other mods patching the same game methods, the wind being handed back to the game (debug wind, world's edge, Moder), mistyped list settings, missing sound names.

HUD: the wind readout names the level (Light, Moderate, Fresh, Strong, Gale) and sits outside the ring from the wind icon.
Logs any frame over 0.3 s while aboard, with the last thing the mod did, to trace stutters. Settings read every physics step are now parsed once per change.

HUD: speed and wind readouts sit on dark plates so they stay legible over the wind icon; speed reads in "kt" with its faster/slower arrow tight beside it; wind strength is shown in knots instead of a level number, still coloured by level; the course arrow is thicker, white with a blue edge like the wind icon.

Fixed the sea slewing and heaving during wind shifts and gusts. The swell now cross-fades to the new wind direction the way vanilla does, once per shift, and gusts no longer raise the waves.
The course marker is now an arrow from the boat icon that gains arrowheads with speed, drawn part transparent. Opacity and knots per arrowhead are client settings.
New "Handling" settings: sail force, paddle force, turning under sail, turning under paddle and rudder speed, plus an experience multiplier.
Editing the config file on a running server now takes effect and reaches clients without a restart.

Windage now depends on how much sail is up: full sail catches the most wind, half sail three quarters of it, and a boat under paddle or stopped half.
Windage brakes a boat pointed into the wind, down to a crawl, in place of the separate in-irons drag. A tack carries through much as in vanilla; a boat left head to wind stops in a third of the time.
Removed the "In irons drag" and "Stopped factor" settings.

Readouts moved onto the vanilla ship HUD: speed in knots with a faster/slower arrow, a course-over-ground marker on the boat icon, wind level on the wind icon, an arrow when the wind is shifting, and the boat icon reddening with hull stress. The separate panel is gone.
Now required on the server and every client.
Closer to vanilla handling: bow fall-off turns the hull without pushing it sideways, skill gives +10% rudder and +5% sail force at 100 (was +25% and +8%), and a sail held head to wind now slows the boat.
Skill experience roughly four times slower.

First build: wind levels, gradual wind shifts and gusts, easier upwind, Seamanship skill, windage, overpressing and the instrument panel.
