That's a later boat based on U.K built Hollands. The U.S boats that used that design were called 'A' boats. The earlier boat that was modelled by RMSS was of similar design, but a smaller submarine and with different deck arrangement. It also had different hydroplane arrangements, when originally built they forward of the prop. Upon feedback from the crews that worked her, they were changed to an aft arrangement.
Good plans of this boat exist, so if a model isn't forthcoming making a new master shouldn't be too troublemsome. The spindle shape makes it a nice subject to turn on a lathe.
Personally I would love to see a model of the Fenian Ram, I believe that was the purest Holland design, with close to ideal proportions.
