It's not just adding treasure, it's adding rep and ship count. We gave this a test last night. Seems that everyone who gets in a shot (or three) as the ship is sinking gets triple rep, gold and ship count. I counted how many ships we sunk on one run, it was 15. When we landed, the ship count showed as 44. (didn't get the triple count off of all the ships, but most of them) I went from 2600 sailing rep to 6200 in two runs.
