The original boat was a 24' Grand National Hydroplane. I purchased the boat new. It is a registered APBA Hydroplane # GN158. One of the photos above shows the boat running in it's original single seat configuration. I put approximately 3 hours on the original boat to do some testing before starting the conversion to a two seater vintage pleasureboat. It now has a float off bunk trailer (no crane required) and always draws a crowd whenever it runs. It's a great vintage show boat and has allowed me to let passengers (including the grandkids) experience the thrill of a true indycar on the water. Top speed two passengers about 80 Mph. and driver only about 110Mph. with a prop change.We are downsizing and selling our lake house some toys will have to go. Also have indycar for sale pictured above if interested in road racing. Be carefull out there, Thanks for looking.
