    I really like the new hull from Strike but, the ship isn't really one I'm interested in.
    I'm wondering how close the shape is to that of a Portland Class cruiser?
    Their length and beam are close at 1/144th scale.

    The Italian ship has almost an inch narrower beam, so well outside the allowable difference at least for the IRCWCC.

    Yeah I looked at that: 4.8" vs 5.5". A 1/4" chunk of balsa glued to each side will fix that.
    I'm just wondering how similar the lines are?
    Does any one know what the midship area coefficients are for these ships?

    I would say they are not even close to similar.

    Just buy the right hull if you want a Portland. Avoid square pegs round holes, etc.

    Or better still, pick a ship you can get on the water quickly that works reliably right now, then use it for a season and build what you really want after getting a bit of experience

    NP, but why wouldn't you want to build the Duca. It should make a quick easy build and best of all...it has CANDY STRIPES? :woot:

    Duca Hull: $20. Portland Hull (roughly 3/4" too short!): $125

    PS. And I already have the Duca hull : P

    That's because it was originally a Northampton hull. Its easy enough to do a quick build up on the bow though, or even bandsawing the hull and extending it amidships.

    Using the duca hull would cost you in interior volume, particularly across the beam, where space is premium. Not to mention the profile being wrong any way you turn it.

    That's the good reason to consider it. But its not a very good fit IMO.

    Personally, you have the duca hull. Build the duca. Its a pretty ship. You try to turn it into something else and you're just making your first warship build a lot harder.

    First... third.... who's counting? What does that matter anyway? You could have just said the shape was different.

    I did. I said it was a round hole, square peg problem.

    Making your first build harder generally means you're not getting on the water. That means you're missing out on valuable opportunities to learn, have fun, etc, and move on to building a better ship. Which is why I tell people not to over-complicate their first build.

    You are killing me... FYI, This will most likely be a temporary plug for a static model that a co-worker asked me to build, after seeing my other ships.

    Honestly, if you wanted to build a Portland, but didn't want to go for their very nice fiberglass hull, you should've just got plans and built your own hull.

    Sure you can put a Portland ss on your Duca, and I'm sure 99% of people wouldn't be able to tell the difference. But when you come to a battle, you will probably get a few people chirping about how wrong it is. Just letting you know.

    LOL. I never said I wanted to build a Portland. What I was after was a hull shaped like a Northhampton but, slightly larger. It turns out that the ship in question isn't a modified CA-26 hull, as I'd been informed. It's a cousin to CA-125... Longer, wider, no deck step. Now, I will agree that the Duca isn't a good donor at all : P

    So your co-worker wants a CA-125 static hull? Is that what you're after?

    Maybe. It's actually AGMR-2 which seems to be 10' wider.

    Looks like a Baltimore hull would better suit. Does he want a static or mobile hull?

    Static

    PS. I found some cross-sections of a sister ship. It looks like a widened CA-125 hull would be good.

    FYI, USS Northampton (CLC-1) was built on a Oregon City class hull which in turn was a knockoff of the Baltimore class but with a different SS. You'd be fine with a longer and wider Baltimore though unless he wants exactly 1/144 a stock Baltimore would work fine as well.
