In regards to the original question, it would be interesting to know what % of their spend is on R&D. I would guess that it varies wildly in years where they introduce a hull, versus making improvements above the waterline.
Investing in making products better is what keeps market leaders on top, if you don’t you will lose market share - granted sometimes you still lose it even if you do!
I love all of the improvements that are available in today’s DD boats. Whether it’s improvements to make maintenance easier, improved engine performance & fuel economy, electronics, interior finishes as simple as making it easy to walk to swim platform without wearing the rear seat, or having places to store skiis...
That said, most of the wake improvements on the SN are things that will never help me as an amateur, so I wonder if manufacturers are doing a disservice to the majority of their customer base by optimizing for the top 5% of skiers.
That would be another interesting break down to see: purchase distribution across skier ability level.
