I really like the Bolitho, it is ship with a sound concept - a gunboat, that is a small ship with a big gun.
Of course it will be chewed up pretty fast in any capship engagements, but as a raider or escort it more than has the punch to ruin any bloody privateer's day.
However there's one thing I don't like about the model: The forward dorsal gun.
This ship already has two over-sized turrets, and I would find even them "unlikely", but the current placement (ventral right and dorsal left side) actually makes it believable, since half of the whole hull can be alloted to servicing a turret each.
On the forward turret there is no such space available. Remember, these big honking guns are more than the turret! You need magazine space, loading mechanisms and the motors to turn the thing....all in all those things take up just as much if not more space than the turret itself.
If you still want "more" guns on the ship (which is alredy pretty overpowered, when you realize a ship of galactica's immeasurable bulk only has a dozen of them) I suggest you go with a spinal mounted weapon...but then again you'd have a very different ship, more of a front line skirmisher than an escort ship.
Never the less the Bolitho will be hard pressed for magazine space and even with "all corners cut" it won't have the magazine endurance for fleet engagements.
