    I don't know this for sure. But, if you want to dampen out foil-roll and snap-roll induced banking (sexy looking but a big ship control issue), differential use of those outboards would be of some assistance, even though their moment arms are short. Such use would put a hell of a 'knuckle' in the water -- so much for stealth.

    As far as I know, yes. I never got to drive a Seawolf, so I am not familiar with if they could be operated independently or not. I suspect they are similar to how the split planes work on a Virginia.

    Thank you for the diagram. That is what I thought you meant but something in my brain was saying NO! For real?!? Did the flap and the tip work in unison?

    Good to know. Not quite sure I am following you though. Do you mean like this or something different?

    Thanks Rob. It is turning out good so far. Very impressive to see in person for sure. Sorry you can't make Subfest. Once I get the mechanical fit and function of the hull sorted out there will be a significant amount of sanding and filling to do mainly because of its size but it will come together. Last year at Subfest I had my Thresher with nothing more than primer on it and now it's done.

    Your "Jimmy Carter" is really an awesome build Steve! Wish I could make SubFest and see it in person!

    Sail and bow planes are printed and fit nicely.

    Stern planes and rudder are printed as well. One thing to note. The stern planes as designed were about 3" long each. Not much surface area for a 113" long boat. I have the Trumpeter 1/144 plastic model of the Seawolf and based on it the stern planes were full span so with a slight modification using a coping saw and a redesign of the planes in Fusion 360 it will be easy to change and add about 1-1/2" to the length of each plane.

    Port side has been modified. Starboard has not for comparison.

    The propulsor shroud mounting flange is bolted on with M4 screws and threaded brass inserts as well as the whole tail piece to make it easier to connect linkages and such.

    I make all my boats with removable sections where needed to ease servicing because eventually it will need to be done.

    I’ll give you a hand. Lol!
