I have master sailing and now that I spend most of my sailing time Privateering, I kind of like this sailing build:
Left Broadside (1/5)
Right Broadside (1/5)
Full Sail (1/5)
Come About (1/5)
Open Fire (5/5)
Ramming Speed (1/5)
Take Cover (3/5)
Windcatcher (4/5)
Tacking (4/5)
Treasure Sense (0/5)
Taskmaster: (5/5)
Total (26/26)
Notes:
I put 1 in full sail and ramming speed simply for a short burst of speed to break away from the pack if I get surrounded. I sometimes like come about when a war sloop is circling. I can sometime break away with it. Treasure sense seems wasted now that I have max gold and all the war ships.
Most of the time when I am sailing I have a crew so I felt that broadsides were less important. I am kind of gimping myself in non PVP but since I don't care about sailing rep, I can always just hop off the wheel and nuke the enemy with my cannons!
This build changes the way you sail in PVP and even in PVE with a crew. I find myself trying harder to keep the ship angle as tight as I can so my crew can fire the cannons and I don't worry about having to line up my broadsides. If something sails broadside, well a little damage is better than nothing. My crew is going to sink it anyway.
The only thing I am not sure on is how much windcatcher and tacking helps. Not sure if would help to take from those 2 skills and beef up broadsides or not.
