    Would any of you chaps (David Merriman?) have an idea of how much an air ballast, static dive, Trumpeter Seawolf would weigh, please? Just an approximate guess will be fine.

    As to the amount of ballast water weight needed for the 1/144 Trumpeter SEAWOLF:

    It matters not what the (free flooding) model submarine weighs. it's the displacement of all structures above waterline that counts. And this models above waterline structures displace about four ounces of water, so you require about four ounces of weight (four ounces of water in the ballast tank) to get this beast to submerged trim.

    Point taken, David... I just wanted to know how much it would weigh and whether if I could lift it without doing anymore damage to my hands. I had to move the half built Skipjack today, and that was a struggle.

    I should have weighed the Dragonfish before she was retired, I never gave it a thought.

    Oh ...

    ... all up, ready to run weight is, just a tad under two-pounds. This, of course, is the operational weight of the Caswell-Merriman converted 1/144 Trumpeter SEAWOLF kit with the items below:
