Here is I believe a 280, but the numbers have fadded -
This photo is from Tampa in '73' also -
Maybe someone will recogize this boat

'racen7' writes he thinks this might be a 280 named 'Miss Ottawa'
that raced in the Kankakee area in the 70's -
Thank's for the input 'racen7'
( That boat sure looks good comin' through there!)
