King Gustaf was designed by Ed Monk, Sr., and built by Jensen Motor Boat as Tony Boy II, owned by Tony Jensen, and was launched Nov. 26, 1952. The dinghy, currently Li'l Gus, was also built by Jensen and was named It's A Boy in honor of the recent birth of DeWitt Jensen. The King was re-powered in 1996 by a previous owner with a Yanmar 4LH-DTE diesel engine. She cruises at 8 knots and uses about 2 gph.
