With the rising cost of good ski boats I'm starting to think that there's a market for cheaper boats that are built solely for the purpose of pulling a water skier. In Europe, most ski clubs would be interested.
Back in the 70s and 80s Club Med used to operate a fleet of purpose built outboards for water ski. They weren't fancy but they were practical and I bet they were cheap.
For a club all you really need is 2 rear facing seats (for judges), zero off, a great engine, good tracking and wake. There's no need for shiny paint, leather seats, etc.
I'm convinced that if such a boat existed it would sell well over here.
