Patch Notes: Two new ships

The Carrack, rebuilt

The Carrack (the pirate flagship and the merchant carrack) is a new model, fully textured.
Ten gunports, each with its own shutter, and a gun on a platform behind every port. Two bow chasers and a stern barrel.
A companion through her middle house leads down to her gun deck.
Her wheel and rudder turn together. Her anchor is weighed and let go, and rope ladders hang down her side.
She carries seven lanterns, so a carrack at sea is lit at night.
Her rig: a spritsail, fore and main courses, a main topsail and a lateen mizzen. They trim with the wind like every other ship.

The Large Boat (the pirate sloop and the coasting trader) is a new clinker-built model.
All seven of her sail plans are rebuilt on the new hull.
She steers by a tiller: a raked rudder on her sternpost, with the helmsman on a step at her stern.
Seven swivel guns sit on her gunwale: three a side and one at her bow.

A carrack's broadside still hits as hard as before, now from five guns a side instead of seven.
The pirate sloop now closes to 50 m (it was 55), because the new boat is a taller target.
Harbours, berths and quays are unchanged.
