Who makes this boat - "Chaser", 28'
 

saw one quickly and could catch the maker of the boat

You're probably talking about a Campion "Chase" 800i (8 meters/26'7") or Chase 910i (9.1 meters/30'). They're made in Kelowna, British Columbia, Canada, and are generally considered to be a pretty good boat:

not the one. It was a basic looking boat, but what caught my eye first was no integrated swim platform on an open bow boat.
