Aye matey, you be getting into dangerous seas. Yer leveled up to wheres sinkin ye is worth more experience points, yet yer not quite strong enough to defend yerself. Puttin her bluntly you are still a small fish and have swum up into a big pond. Keep at buildin yer crew and keep giftin yer mates so as they be returnin the favor. Also helps to have good crew that is stronger than ye so as they can revenge anyone that sinks ye. If'in yer not already on me crew, be sures ta sends me an invite as I be just that kind of mate. The only attackin I do is to revenge me crew when some scallywag is foolhearty enough to pick on em.
