I forgot I had another. This one will serve as a scout and leader to the previous ships. With the majority of DKB destroyers mounting a relatively light main armament this ship is sufficiently heavily armed to counter them.

Ahoj!
I'm not sure about the "oceangoing" part of the description ...
Borys
'Oceangoing' compared to the 15 ton MAS boats I will be building alongside... ;)
Ahoj!
In THAT context it is indeed appropriate :)
Borys
Agreed with Borys on the "oceangoing" definition.
Seekan II - she'll be a very crowded little boat, but if it fits, it'll be a challenge for those DKB GTBs. Is there wireless included?
Yes, 4 for the torps, 5 for the wireless. These ships will have to take over the scouting role for NZ.
I'm not sure if the 1st design is worth it. Slower,weaker, and short-legged, probably would be a better idea to build the 50 ton Turbinias instead.
I think the Mods will have to lay out a tech tree for MAS-type craft before you'll want to go too far down that road.
Originaly to be a Gunboat, this design ends up as a torpedoboat leader for the Seekans, freeing up the Lavis for more important duties.
