GOOD EFFING LORD...what is this "THING"?

Mine was blue w/ white vinyl top. Thanks for the photo. “Dolphin”, “Bowfin”(1944), the original “Invader” before it flipped over in an Everett shipyard, other old Crowley stuff and most recently the “Impala” (1967ish?). Oldies but goodies… LOL I’m looking forward to a warmer climate and some new steel!
