Indeed I have been contacted! Greetings!
I am the creator of this ship you all are discussing. Thank you bonaparte for inviting me into the discussion.
First of all this ship does not use lego standard hull sections. It is fully built up of bricks. The base of it is made using mostly 8x16 brick plates, then 45-degree inverse black 2x2 slopes are used to angle the hull up from the water line (which is a close approximation to the angle of a "standard" boat hull).
This is done for two reasons, first and foremost because I needed to make the ship much wider than the boat hulls allow to get a proper length to beam ratio that "looked" right, that and it allowed me to use whatever colors I wanted, in this case black and yellow (with some blue trim inboard). The second reason is strength, this model is extremely strongly built. I can grap it up with two hands by the nose and flip it up completely vertical without it bending or breaking and it weighs nearly 20 lbs (and it's fun to watch people wince)! Why overbuild it this strong? Because it does shows, it has to endure loading and unloading at various venues.
Were it to have been done with boat hulls you'd need to cut them to spread them wider and then I'd say it's close to 6 or 7 mid-sections long (from stem to stern I think it's something like 18 to 24 inches)...I can measure it at home if anyone is interested in the exact dimensions...
However it is mostly hollow, it's not just full of junk-color bricks, it has distinct gun decks, but it is built at about 1/2 minifig scale (1 stud = ~2 feet), although it typically gets figs put on it at shows for the kids.
There are lego cannon on the two main gun decks, there are a little over 50 cannon. The upper deck has my version of carronades (which is historically innacurate for Bellerophon, but plausable...USS Constitution's original specification was for the upper deck to be all Carronades, and is her current gun configuration as she sits in Boston after her last renovation). That was mostly done for aesthetic reasons. To keep the upper deck "clean" looking. Plus lego cannon are NOT cheap. I think it was the single most expensive part of the build on that model. In all the ship has a main battery of 80 guns (40 per side) with two bow chasers and two stern chasers. The reason the cannons aren't able to be "run out" is again, because of transportation and maintenence concerns. If they were on wheels and loose there'd be no way I could get into the ship to upright them or align them if they got jostled around in a car ride. The cannon are simply secured down to the plates they're mounted on. They're not permanently out or the gun doors couldn't close...a compromise so to speak. In any case you wouldn't want to get close to this ship's broadside were I to use it in a Lego Naval sim game :-P, if you set a Black Seas Baraccuda next to it the lower gun deck is at hull level on the BSB, the mid gun deck is at main deck level of the BSB and the upper deck would be around the quarter deck and upper masts of the BSB...it wouldn't stand a chance I'm afraid...
As for the masts...yes they are shorter than spec but they were as tall as I could make lego masts be without resorting to using some odd looking technic device or building them out of 2/2 rounds (which would have been fairly unstable). Again this was chosen for the robust characteristics of the lego masts. With all the sails on, at outdoors shows this thing has been known to actually catch the wind. Usually the masts hold...if they were less strong they'd often break, either in transit or in outdoor winds. That and, the lego masts are aesthetically "better" looking IMHO.
The bulges on the aft-cabin were again a compromise. I wanted to use the lattice-pane windows for a better aesthetic look but mounting them on an angle was difficult and there needed to be a slight bulge there for the aft-cabin (that's where the captain's privvy was BTW...well on some ships!). I ended up playing around with some bits and pieces untill I managed that design. It isn't the best but it's relatively decent. The back of the aft-cabin I feel is somewhat accurate, it would have been rows of ornate windows and such, especially on larger, prestigious ships of the line. I'm not sure on 3rd-Rates but certainly on 2nd and 1st rate SOTL on which admirals of the fleet may have commanded aft cabins would have been opulent in some cases. The window section of the back folds down (it's the same concept as the back of the BSB) and you can access the interior of the aft-cabin. It's not furnished, but the upper portion has a black and white parquet floor.
Another notable aspect of this model is that I completely rendered it in MLCAD. I knew how I wanted to build it from building Constitution free hand. So I did a complete virtual build of the whole model, primarily to generate a shopping list, and work out proportions. Then I bought exact amounts of parts on BrickLink. Doing it this way made it very cost effective to build. As I said the Cannon were expensive...however the overall total parts cost was about $250 USD. There are around 2,500 parts in the model. At $0.10 a part that is spot on what the cost ratio is for a purchased lego set. The cannon averaged $2.00 each...but black and especially yellow brick is dirt cheap comparitively. I do indeed have plans in the future for a 1st rate, and it will of course be Nelson's Victory >8-)
Here is Bellerophon and Constitution at a purpose built dockyard on the IndyLUG section of the ILTCO layout at the 2006 NMRA National Train Show this past year in Philadelphia...
How do you put a naval scene in a train show? The idea is a naval parade celebrating Independance Day in the USA (The show was held the weekend after Independance Day, which is July 4th)
