Don't bother putting more than one skill point in ramming speed or Come About. Your rarely use Ramming Speed it except for a quick burst of speed and Come about is rarely required. Broadsides are important.. try to make both sides even at the very least. Take Cover is very useful in Boss Battles and when battling high level ships so put a couple there. Other than that it's really at your digression, but definitely try to put at least one skill point in each..
