Agree anything less than 20 is not optimal

Any of the Ri series, FS Series, etc. will surf great in over 15 feet and ideally over 20 feet. They will surf decently as low as 10 feet of depth, however you need to slow the boat down. As an example, you can get a respectable surf wave on a Ri257 w/ stock ballast in 10 feet of depth but you are going around 9.8MPH. Typically you would surf on a Ri257 at 11.2mph. At 8 feet the waves become essentially impossible to clean up. Any decrease in depth below 20 feet needs to be met with a decrease in speed. Your wave will be shorter, but you can keep the power and mass.

My 257 is out for the season but went out on my buddy's 237 and anything under about 20' the wave quality went way down.

^^^that boat throws the biggest pushiest wave I have ever ridden and seen. There's definitely push in the white wash WAY behind the boat.
