To claim someones boat you need to place a claim flag on it and wait 14 hours?!!? to claim it, during that time you cannot leave the boat otherwise it will remove the flag meaning you have to stand on the boat logged in for 14 hours!??!!? The last skill in pirating says it greatly accelerates the rate of the flag claim timer however I've been testing it and it only removes roughly 30 seconds off the timer... 30 seconds off 14 hours is nothing, making the skill useless. To claim a Sloop you shouldn't have to wait any longer then an hour, not 14 hours, that makes it impossible to take over another boat.
