The boat was originally owned and raced by "Racer Bob" Dabrowski from the Detroit area as a 225 called The Specialist. I don't know specifics but according to Bob, he won quite a few races with it running a highly modified Buick 215 cid. After Bob, the boat raced as a 225, 5 Litre and a NM. The last person to race the boat was Bill Densten from Millville, NJ area as a 5 Litre/NM.
