Jeff Brown's 'Pure Insanity' P-38 was the first Scarab to win The US National Offshore Championship (1979). Don Noble of Mission Viejo, CA later raced her with great success in the 80's as P-38, converted from 280's to KAAMA drives and was among other things 1984 MBRA World Record Holder Pro IIIA. She still has the KAAMA drives. Here's a couple of photos.
