I won't be able to get on but I'll give you some tips that might help with the more-challenging boss battle.
1: Keep your distance from the bridges, you get less hits which should keep the Pearl in better condition. Let the crew handle them with cannons.
2: Just sailing past them doesn't work anymore, they still hit you with double damage including the bridges the ship is closest to. All the bridges you pass will keep attacking.
3: If you manage to get to the Golith, the best way to avoid sinking is to use full sail/ramming speed as soon as you enter the finale. No turns, only a slight left movement when your far away from the Golith. The pirates on the left side of the Pearl can sink her with fire/lightning/fury while the captian keeps his or her distance.
Note that with the update, the battle is 10 times harder so be patient and take your time.
I wish you and your crew the best of luck.
