I had one new as a kid. Great boat that we used with a 4 then 8hp 2 stroke Yamaha. No GPS back then, but think it did about 20kts with 2 kids and the 8hp. Available in cream/blue and cream/brown from around 1980-1985 (estimate). Had proper wooden oars and pin type oar locks.
We used to break the windscreen with alarming regularity, easily replaced with home made version. Floor was a huge PITA to fit, a little air in the tubes and placing an oar under the hull helps.
Great boat that I remember with a smile, only replaced when grandad ran over it with our speedboat
