So with today being my Friday off I proceeded north, along the coast to Kittery, Maine.  Along the way I stopped in Portsmouth, NH for some lunch (Portsmouth Brewery Restaraunt, yum). But it was a historical sign that pulled me off the highway originally.  After lunch I visited it.

The forward berthing area (tight bunks)
Hatch to somewhere, I forgot to actually see where it went.
Chart room
Controls
Engine room (that thing running along the center is the propeller shaft housing.
A very fine rear if I say so myself.
View from starboard looking forward.
Quite a pretty little boat isn't it?
