Dangerous Wave's and Stronger Skeletal wave's

So starting with the Dangerous waves i thought that sometimes very rarely waves will come a bit higher and splash some water onto your ship at the very moment the water splashes onto your vessel from the wave you can collect water to your bucket from it. And sometimes precious gems that were lost in the waves can be splashed onto your ship as well but to make the storm a bit more fun and dangerous the waves will be extremely huge and common being thrown onto your ship and skeletons will most likely appear onto your ship from these waves along with their swords and guns if they succeed on killing your entire crew all at once they will try and bring your ship down below the waves driving it into any rock they can find in the storm or either keeping you and your crew at bay till it sinks. The next idea i had is after every 3 waves in a skull fort a special wave will appear one being a mixture of different skeletons types and one with a skeletal banner on its back with little less than half the health of the boss Captain at the end if near death it will back up and bring up its war horn and call all it's busy skeleton troops even if they are busy or not to itself and try and kill everyone all at once defending it.
