Your model really does look neatly done! I love seeing such a huge scale ship and boat, I am guessing that is quite rare. Thanks for sharing the video it is well done.
Regarding the plan that you used, it is a shame you could not get more detailed information. For the future, if they want additional boats (
Venerable would have had six

), there are nearly 50 very detailed RMG plans of ships' boats in high resolution on the Wiki Commons site including 14 pinnace drawings available for free download. There are also books with details that would be helpful for anyone building a ship's boat such as
The Arming and Fitting of English Ships of War, chapters 38-43, and T
he Boats of Men of War by W. E. May. Boat scantlings can be found in the book by May, as well as in David Steel's
The Elements and Practice of Naval Architecture and
Scantlings of Royal Navy Ships.
