Shipbucket

looks a lot better to me.
few problems remain:
- the funnels are going straight through your 'bay'. if your landing craft are aft, why do you have those anyways?
- I assume you have mk 48 mod 1 placed? could work like this, but why not play safe and use mod 0 or mod 3?
- of course this will be in your specs, but what radar type will you use?
- last thing: the stabiliser/rudder aft will most likely make it impossible for your ship to lay alongside another ship or an quay. not something I would want....

main reason for a trimaran is that the center hull shall stop the boat from going through the sea. it will give the boat extra buoyancy when the boat crash into the sea. It may be uncomfortable due to the advancing movement you have, which is the main reason why it is not really such many boats with this hull type. But if you have to use it the you use it.

I think I have gone as far as I can with this project. After some advice and radical changes to the design here is JB. Specifications

Looks good, and better balanced would it be possible to vent the exhaust between the hulls?

I was thinking of that actually. Would clean up the lines of this vessel. Was thinking a dual gas turbine/diesel exhaust underneath the flightdeck either side of the centre hull, like that of the South African Valour Class. You wouldn't see it on the drawings but I could always amend the specs.

The last post has been modified accordingly. Hope this is a better idea.

Very nice, but I think the gun is 76mm not 127mm .

The 76mm has a very restricted field of fire, but other than that it looks great as always.

A very well drawn ship. Just for the sake of clarity, would you please describe the mission you have in mind for the ships?
