No, Fleet Admiral Talia will have 3 cogs and a river barge when it is all said and done. Won't have enough to crew them all at one time, but you have to take what you can get.
The Whoa Buoy will be mostly her home/sanctum area, don't plan to move her for a while.
The Atta Buoy will be for travel along the length of the lake, it may also be the test platform for experimentation when she builds a Hermetic shipyard. She's not ready for that, yet.
The Go Get 'em Buoys will be for the North Atlantic.
The river barge is for the River Ness only. Trying to move a barge on a deep water lake like Loch Ness is probably rather difficult.. The River Ness is only 6 or 8 miles long, should be easily reachable in a day from the source at Loch Ness. And I'm kicking myself for not just inventing instaboat spell right about now. Oh well, the wood for the Barge is important to get something of proper size.
