Besides the fact that we are all getting Lefts every single day since the last patch, once that issue is corrected I think the following should be implemented.

Instead of receiving 1/2 the rewards for setting sail and half the rewards when you finish..

Pirates takes 10 minutes to complete

So for every minute you make it you receive 10% of teh full rewards.

If you are sunk in under 1 min you receive nothing.
1min to 1:59 you get 10%
2min to 2:59 you get 20% etc etc

Oh and bring back the sail reset when you coin
