If the boat previously pictured wasn't a ski-boat, then my recollection of the photo-details was
deficient.
I'd have to ask NHMP Lt. Dunleavey about the fact of his approximate speed.
When this forum is actually given the fact of physical evidence (such as a photograph), it
will get a thorough "going-over".
The OP was
"too-smart-by-half", and needs to be recalled to the
winni.com witness stand for one more question.
