Take the offer. Go to Your captain and tell him you have an idea. Explain to him how the Captain of the Cougar paid you to leave him alone, and we attempt to do that with every merchant ship we come across. If all of them do decide to pay, then one of them would have an unfortunate accident at sea anyway.
If we did this, our captain is either going to attack the ship anyways or make you split your payment with the rest of the crew, or probably both. It doesn't benefit him to not attack the ship just because you got some gold out of it.
I agree with the first part, although I'm going to change the rest a little.
Take the offer, convincing him of your ability and willingness to help him for this single voyage. Get the payment and go back to your own ship to store your newly earned money wherever you've been safely storing the rest of your loot. Ensure that it is not exposed or held suspiciously at any time while walking. Under no circumstances allow the money to be stolen, lost, or noticed by anyone on your way to the ship.
Be especially alert for any deus ex machina that may attempt to reveal the gold and consequently the deal you made, which would expose your lies and cause your crew to go out after the Cougar despite the fact you don't want to. Take every precaution to ensure this doesn't happen.
After the gold is stored safely, go back to whoever told you to check out the Cougar earlier, and report that you overheard people talking about how the Cougar has purchased protection for this voyage (which is technically true). Tell them it seemed like far too much risk for such a small payoff, since they're just carrying some sugar, and that you guess the crew will just have to enjoy their night in town having a good time as originally planned.
If you're not at the tavern yet, go to the tavern. Get some drinks, be social with whoever's there, and enjoy a long evening of general merriment. Charismatically engage a wench or other potentially willing woman until you've ensured yourself lodgings and company for the night. Of course, such lodgings don't necessarily need to be free.
If anyone else brings up the Cougar before the above actions can be carried out, use your charisma to nonchalantly defuse the conversation before it can start and change the subject. However, don't do it in a way that might make people suspicious or have them possibly think that you might have been paid off or be lying. If it seems like some supernatural force is attempting to steer fate toward the crew leaving town tonight for any reason, especially anything to do with the Cougar, then be sure to do everything in your power to stop it from happening.
If worse comes to worst and it somehow becomes completely impossible to avoid the crew leaving town tonight, then use your stealth to abandon the pirates altogether, and find somewhere effective to hide until they've left. After all, if they eventually come back, you can pretend you didn't know they were leaving, or say you got caught up with something and didn't make it back in time. After they're gone, continue the original actions which were interrupted.
If it was not only impossible to avoid the crew leaving tonight, but also impossible to avoid you leaving with the crew, then commit suicide in the most efficient way with the highest probability of killing yourself. A good example would be stabbing yourself in the throat repeatedly until you die, or putting a gun in your mouth and shooting up through the top of your head. If even this is somehow impossible, bite your own tongue off and purposely inhale the blood, so you'll either bleed to death or drown. If you're knocked unconscious at any point, and you wake up in the same situation (being forced to leave town, or already outside of town), constantly try resuming this action until you're finally dead.
