I think there were several Miss Winnipesaukees and the max. speed was about 35 mph. I’m not sure of these facts. Does anyone know the truth?
What is fast is very relative as I’m sure FLL will agree. My 13 foot Whaler with a 25 hp seemed fast because of your closeness to the water.
I once made it from Wolfeboro Bay to Sheps in 15 minutes

in a Montauk Whaler with a 90 hp. This was with calm water.
Now I have slowed done a little with an older boat on Winnie. I am looking for a new to me boat for Florida which will be smaller.
