Hey Bob,
Have never met you but can tell you know what you are doing when it comes to singehanding.
I think the Cheshire is alot heavier than 170 lbs will give you a better figure after talking to manufacturer tommorrow. Am very much interested in racing can't make it from North Carolina to Mississippi but could make it to Spring Fever. Want to make Cheshire one design a legal class have you ever encountered one before? Want to make sure I can race before hooking up the trailer. I wouldn't worry about me my 225lb butt and a case of beer and lunch won't upset the guidelines.
Here is the Cheshire website. I'm the guy on the Isotope Shark boat.
