Welcome to the board, I am in my 18th year of steam boating but have followed it with my family for most of my life, a few books you may want to purchase are Steamboats and Modern Steam Launches, Reed's Yachts and Trawlers ...both are available from Boathouse books which you can find in the website for Elliot Bay Steam Launch Company.
http://www.steamlaunch.com/ another book is more of a picture book and is called "The Steam Launch"
I would also like to invite you to visit my steam launch web page at
http://www.slphoebesnow.com and while you are looking around the Associations Link click on the the Icon for "The North American Steamboat Association" and print out a membership form and put me down as a referral, I get nothing from this except adding you to the membership roster and sending you a magazine every 2 months as I am a volunteer.
I also have 2 recent links under steamboat rally's which might float your boat. pun intended
Welcome,
Don Fenstermacher, Jr.
