    You should get that battery lower in the boat, like directly on top of the water channel. Consider moving the bottle forward and putting battery where the bottle is. Otherwise stability will be ugly

    You are getting up there in weight, you really want to keep her under 8 if possible

    Where did you get plans for Duca, my sister wants to build one. We will by the strike deck/hull (low cost) but need plans

    Not sure strike is open for business anymore? One thing about this hull they are a pain to get any kind of adhesive to adhere to it. If you spot heat it it helps. Oh plans came from Profile Morskie

    On mine hot melt glue and contact cement work. Whenever possible I used heat set inserts and screws

Weight is 8lbs 8oz. Most likely going to be just under 10lbs when complete loaded co2 and ammo

    you are going to be unhappy with this boat at 10 pounds. Drop half your guns (move to 1 unit twins) or go to 3d printed cannons. My initial build was north of 9, and she did not handle well.

    I also recommend removing the bow guns. If needed you can shift to plastic tubing for magazines. I would be worried about fore/aft weight distribution too. You can figure out the center of gravity by finding the balance point of the boat when placing it on the edge of a 2x4 or similar. On most boats it should be a few inches aft of the fore/aft midpoint. Right now it seems like most of the heavy items are aft, on cruisers I typically need to add weight to the bow and/or shift battery and bottle as far forward as possible. Looks like great workmanship though

    If you have a 3d printer let me know, I will dig up my roll reducing rudder for you

    Thanks kevin mean a lot coming from an experienced builder as your self. More then likely the bow guns will come out to save weight and shift things forward. I could easily drop a pound by removing those. There may be some weight savings in the battery also? Could I get away with a smaller battery currently has a 2s 5200mah?

    I wish I did have a printer that seems to be the current wave everyone’s on. The possibility’s are endless. I’ve seen some of the SS that are 3D just crazy details. But my Admrial already calls my ships the other women LOL.

    The weight distribution is dead center of the ship when balancing on a 2x4

    the center of buoyancy is abou8t 26.5 inches measured from the bow.

    Been a while since my last update working on sheeting . Also coated the deck with west marine got the SS painted. I incorporated my pump discharge into D turret 7B148C76-A266-4749-9FB2-5DBB5D11DBFD.jpeg C13AFEFF-2406-45A5-A8C6-064A2B22A271.jpeg 6A23C1B0-7B39-4072-906C-E24A9487FFC2.jpeg 9A3B2359-8794-4C16-8B82-E3EDA20D0927.jpeg

    I like your rudder. mine is shown below before post print forming. the diagonal vanes are torch heated and folded over so they form almost a cup shape directing flow downward. They actually help reduce roll in turns because the side towards the props directs the flow down but not in line with the centerplane of the hull, which naturally counters the tenancy to roll down hard that this ship has with the enlarged fast gun rudders. Seemed to do more than bilge keels
