Axis made significant changes to the A20 in 2016; supposedly a better hull, much better upholstery, and for some reason they seem to change the (plastic) dash every year. Anyway, I bought a 2016 A20 last year and I'm a total beginner at surfing but we were really happy with it. With the wedge, surf gate, and dealer-installed PNP ballast, it's easy to set up, get up, and start surfing. I'll put 2 videos below but this is with only 4 people in the boat (kids). The wave cleans up and gets a lot longer if you put an adult or two in the bow (or another sac).
I'm actually really happy with the boat. The wakeboard wave is sweet (previous boats I owned: 89 mastercraft prostar 190, 04 sanger v210). Surf wave (to me) is great, but I've never tried to surf anything else. We don't have any rattles, shakes, cracks, or anything weird, even in rough water. It definitely doesn't perform as well as the V210, but the boat is significantly taller and we didn't expect it to perform as well. When I say performance I'm more talking about maneuvering, not power. I have the base engine and it's more than enough to pull wakeboarders and surfers even with full pnp ballast and a bunch of people.
I've had to have a few warranty repairs done: upholstery blemishes that were there when I bought it (dealer replaced the skin), a cup holder popping out (duct was run poorly and was pushing up on it), stereo kept freezing up (dealer replaced head unit), and the center fiberglass floor cover (separate from the hull) had cracks all over it, which they repaired (note: this is a cover for an access hole, not part of the hull itself). The repairs were done over the winter so I didn't have any downtime.
Yes, there is a lot of plastic in the boat. Glove box, dash, etc. However the boat is significantly cheaper than comparables (even moomba, when I was looking) and we haven't had any mechanical or electrical or hull issues at all.
We have had a number of problems with the axis-brand trailer. Poor wiring, crappy paint, improper bunk placement that made loading the boat problematic. After a little bit of back-and-forth with the dealer, and a single phone call to Axis customer support, the trailer is being completely stripped and repainted, the bunks repositioned, and the wiring fixed up. A couple other people have had problems similar to this (on axis forums), but most people don't have any issues. I'm happy that Axis/Malibu took care of the problems.
