The Old Chronian Refit (Caelanor Mast Platforms 3.0.0)

The Old Chronian mod's Caelanor and Aelasyl refitted to fight: fighting tops and lookout posts on their masts, lower ratlines and leaning futtock ladders you can climb, a walkable net slung under the bowsprit, copper sheathing below the water, davits over the frigate's stern, and a bilge pump for the frigate. Everything is bought at the shipyard, with the ship's own parts. Nothing in the Old Chronian mod itself is changed.

This is the same plugin that ships inside Dangerous Waters. Install one or the other, not both: if both are present BepInEx loads one copy and skips the other (same plugin ID). With Dangerous Waters you also get Gun Port Lids as a shipyard option, the Caelanor's sliding fore hatch and the frigate's trim; those are part of Dangerous Waters, not of this plugin.

This plugin replaces the old separate Caelanor Mast Platforms (2.6.2). If you have that one, delete its folder; if you forget, BepInEx skips it anyway.

Requirements

• Sailwind, BepInEx 5 (installed by Thunderstore Mod Manager / r2modman)
• The Old Chronian ship mod (the ships themselves)

Optional, each adds one thing:

• Dinghies (Thunderstore, Pr0SkyNesis) - the Aelasyl's stern davits and the boat in them. Without it no davits are offered.
• Old Chronian Fixes (Discord, with Old Chronian) - gives the Caelanor her bilge pump; with it installed the Aelasyl gets the same pump. Without it she has none.
• Shipyard Expansion (Discord) - the copper sheathing wears its copper, matching the brig's. Without it the sheathing wears a plain copper of its own.

Old Chronian itself is a Discord mod, not on Thunderstore, so a mod manager cannot fetch it for you: install it by hand first.

Install

Unzip into BepInEx\plugins\. You should get:

BepInEx\plugins\CaelanorMastPlatforms\CaelanorMastPlatforms.dll
BepInEx\plugins\CaelanorMastPlatforms\CaelanorHatchFix.dll

The second file is the Caelanor Hatch Walk Collider Fix (by Dixiecapt): the Caelanor's cabin hatch has an invisible walk collider twice the length of the opening, which blocks the companionway even with the hatch open; this slims it to the hatch itself. If you already have it installed elsewhere, keep one copy.

Start the game. The settings file BepInEx\config\com.dixiecapt.caelanormastplatforms.cfg (or the name your log shows) is written on the first run; press F1 (Configuration Manager) for the few settings there are.

What you get, and where to buy it

Take the Caelanor or the Aelasyl into any shipyard.

Fitted as she loads, nothing to buy: the lower ratlines laid rope by rope on her own shrouds, the futtock ladders to every top, and the gap ropes where a gun port leaves a shroud out of the Aelasyl's netting.

Climbing

Every rope lights when you look at it. Look at a horizontal line (a ratline, a rung) and click: up. Look at a vertical line (a topmast shroud, a stay) and click: down. The leaning futtock ropes differ by ship: on the Caelanor they click up, like the rungs; on the Aelasyl they click down, to her deck. The topmast shrouds above a top can also be walked, slowly, the old way.

The net

A safety net for the men on the headsails, slung under the bowsprit: tied to the bow under the spar, its corners lashed round the catheads, its point tied round the spar's end, the middle hanging like a hammock. Jump into it from the bow rail and walk out to the point; it holds you, and so does the drop from the spar. It passes through the beakhead, as a net with holes may.

Two copies of Old Chronian

The refit reads the ships' own rigging to place its ropes. On the Thunderstore copy of Old Chronian some of that rigging cannot be read, and the plugin falls back on measured tables for the lower ratlines and the futtock feet, lays the copper by tracing the hull instead of cutting it, and leaves out the gap ropes. Nothing fails; the fit is simply closest on the rebuilt Old Chronian the plugin was made against.

Reporting bugs

Send BepInEx\LogOutput.log from the session, with the ship and what you were doing. The plugin writes a line for every fitting it makes, and the answer is nearly always in there. Discord: the Sailwind modding channels.
