On our recent travels in the US we visited the Shelburne Museum in North Vermont.
One of the main exhibits was the Lake Champlain steamer Ticonderoga which dates back to 1906. A superb job has been made of preserving the ship which was hauled over two miles from the lakeside to its present location.
An album detailing the ship can be found
here
Plans are available from the Shelburne Museum which include plan and elevation views but not hull sections.
It would certainly make an interesting modelling project.
