um, Wind booster anyone?

Shadower's savage blow will be freaking speed demon with wind booster.

For a captain, triple fire, BS cannon, and BS torpedo are affected by wind booster. Those skills act almost exactly like Strafe and Iron Arrow.

It's only rapid fire that isn't affected by booster, and most captains will be using BS cannon more anyway.

With normal booster, savage blow is already maxed out in speed unless you're using a kebob. It will be uneffected by wind booster.
