Many new inboards have special systems to help the surf wake. These are convenient but only show up in the last few years. Most wake surfing requires lots of extra weight in the boat and then the boat being listed to the side that is being surfed on. That is a bit easier with a deeper V in the hull.
You really want a cruise control, like PerfectPass.
You want a lower pitch prop than is stock. That helps maintain speed better in the 10-12 mph range and gets you started better with a heavily loaded boat.
You want board racks to keep everything out of the way as some of your interior space is likely taken up by water filled Fat Sacs.
The addicts use smaller swim platforms that are raised higher than normal to avoid messing with the wake. That's a pain and I don't worry about it.
You
must have an inboard, either a D-drive or a V-drive. A V-drive is a bit better for surfing.
You need a short rope. I use a short length off an old ski rope with a small handle but you can get specialty wake surf ropes.
Getting an
FAE makes the sport safer and quieter so it is a really valuable addition. That should be a factory option on inboards.
It's lots of fun, you burn lots of fuel, and more people in the boat is extra ballast but it means you'll be pulling more people and burning more fuel.
