Yes, the Floating sheerlegs is great idea, but i thought on something other thing. Would be awesome to make, and drive the famous US Coast Guards fleet!
Just see it.. Sure, release in a new addon name maybe Coast Guards: SAR Seas
try to catch smugglers, search with 3-4 rescue boat a lost boat, or brings ships to safe place in storm..Surching ships and try to find illegal contents, This is just some ideas. The best if you make hidden checkpoints, and try to find the ships with binoculars, radar and i have an idea with a sonar. The US coast guards have lot of special wessels, just see the training sailship, in this site you see the ships(boats, cutters)
Well, they have 30 ships

I remember the New York mod for Shipsim 2006, and was great to see the Coast Guard ship there.
Ok, this is only an idea, not more..But just why not payware addons, like in flightsim? Historical addons, and SAR addons, Tug addons etc?..
I thought on another idea the Surface Effect Wessel HSS, or a Surface Effect plane!
