ProSail was the first professional yacht racing circuit in the world. MRI was hired to build four (4) identical boats for one design racing. Two other existing 40’ cats joined in for the money.
ProSail’s star was Tom Blackaller.
When the boats were hauled out and dismantled they fit onto a custom trailer making a very nice neat package for easy shipping. The group traveled around the nation and did six (6) week long regattas and ProSail awarded two (2) million dollars in prize money. I went with them as technical advisor, boatbuilder and measurer, hoping to increase sales. Nothing like 25 knots around the course. The circuit lasted two years before there man in charge of their sponsor was promoted and the next guy canceled.
