[Starfury]

I've been playing, up to lvl 13 but my weapon skills are

Cutlas/Pistol: 6
Doll: 5
Dagger: 1
Cannon: 3 (never on a crew, need to work on that)
Sailing: 7

What I'm looking for: best way to spend the skill points? I don't want to buy useless skills and regret it later. Is there a guide on this?

Thanks much!
