I believe teh CONCH was built off of a FORMULA 233 copy with some SEACRAFT transom design with multi stage V bottom. It was a unique hull design from down in the keys. I haven't seen but one or two myself, but I know they were very popular guide boats in south Florida.
And the BERTRAM 20 BARROn is a DEEP V sucker.

Heres one running at speed. Look at how much of the V is out of the water.
