Hi Mike!
Yes, I hired Lon Acheson in '04 to survey a Silverton on Kent Island that I was hot for.
Fortunately (for me), Lon did a thorough job and found a number of serious deficiencies that I had completely missed. I was present for the entire dry survey. Long story short, I didn't buy the boat but to this day I thank Lon for the good job, allowing me to avoid a LOT of frustration and future problems.
As a side note, I was so impressed with Lon that 7 or 8 months later I contacted him again and invited him to survey another boat for me- this time over 400 miles away. I offered to pay his travel time but he was busy in Florida doing insurance surveys after a big storm.
Bottom line, he's an A+ surveyor.
