Stephen,
That is a 30... We give him (John McCain in the Pic) a hard time about needing to add some sacs..
the crew was what you see plus 2 adults totalling around 300lbs.. needed a Little more weight... the X30 with about 6-8 adults and factory is nice..
Halloween face in the pic has 08 XStar with the proX ballast system added on.. he plumbed the front 2 sacs to be able to operate independently so we could fill one side for surfing.. you fill factory ballast and rear proX plus most of front proX and it is a great wave for Xstar.
If you want easy, great surf wave, add the proX setup to your X45..
with just factory and this crew, we have to keep a bit of a left turn going to keep the wave..
obviously, the ladies and the young guy got a better wave than us since they weigh less and more of us in the boat.
SO, to answer you question, cheap, take 6-8 friends, spend a little, add the pro-x setup.
DTW...
Yep.. good times..
