I have been thinking about doing a larger player controlled water craft such as the frigates. Only problem is that I dont think it will fit the game of PR.
However, the mod I am making wont be a new faction for PR such as the other community mods. I will, along with some other people, make pretty much all the inventory of the danish military (at some point in time) regardless of it fits the game mechanics of PR or not - artillery, boats... we have come to see PR as sort of a combat simulation platform engine, and if we want to simulate a C-130 hercules, well then we do it (yes I know there cant be that many players, and stuff cant be put in the back - so what?)...
That is why it wont be made official like the community mods here, but when we are done we can put in the equipment we have, and PR uses game wise at that point for an official release.
The people that are making the faction is me and some of my study mates at my university. We are all studying to become game designers and the rest of them wanted to learn a few things about modding.
as for the boats, for now the plan is to test out the ship dynamics and such on a craft like this:

Its a patrol boat class ship.
and I have a nearly completed model of a vietnam style ASPB laying around I had planned to import and test a while back:
