Axis A22-need weight advice
 

I have a 2015 A22. I wakeboard 99% of the time but we like to surf from time to time so I've been trying to dial the wake in an haven't had much luck. For those of you who have the A22, how do you weight the boat and what speed do you find has the best surf wake? I've got plug & play plus the surf gate. I have 450# bags in the rear, plus 500# lead throughout the boat, mostly in the bow along with the front & center ballast.
I've fully weighted down the riding side rear bag along with the rest of the ballast, surf gate, and wedge and ride about 13 mph but the wake doesn't seem to be that crisp and we are not able to ride for long without the rope. Any advice on what makes the best shape wake?

Go to 750s in the rear and slow the boat to 10.5-11mph (confirm with gps).

I had 750's originally when I bought the boat and I sold them and downgraded to the 450's. It was too much weight in the rear and the boat wouldn't plane out when fully weighted, even with bow ballast plus 500lb lead in the bow. I'll try a slower speed though and see how it goes. Do you see any difference when surfing with having lots of bow weight vs just rear heavy?

Rear weight gives the wake height....bow weight gives it length! My T23 we ride at 11.6.

Having the same issue. T22 though. P

It's annoying to play the guessing game with rear weight when you have big sacks and want to go
The wake gets stupid wide when you overweight the rear of the boat.


But for the 5% of time I surf I don't want to have too little weight. Thinking I may go 600s.


But yea I would slow down.

What prop are you guys running that you can't get on plane with 750s? That's standard plug n play. You will need high torque prop.

I am not worried about planing, I will reprop if needed- I just dont want to have to add even more bow weight when wakeboarding. It gets old filling sacks and the boat has to sit on a 5000# capacity boat life so lead is not an option for me. It also gets tricky playing the "how much weight is in the back" and "are my 2 sacs even" guessing games when partially filling large sacs, it also adds the slosh factor. The boat also has the 6.0 which I was told is 200 lbs heavier in the stern.

I don't have as much experience weighting these boats like I do MC/Tige's. I know the wake gets very wide with rear weight. DO they like a 50/50 ratio? 40/60? With wedge vs without?

I don't think that rear weight has anything to do with how wide the wake is. I've been riding behind Axis boats for years and have never observed that.

Almost everyone I know runs a sac on the front seats to get the best wake possible. Even just 2-300 in lead would be a big help.

I have a 15 A22 and also could not get the 750s on plane. I have the small motor with the 1235 and the 2315 (the most aggressive props). Maybe you have the big motor?

The problem with the 750s and using them for wakeboarding, is that when you run them partially full, you're going to get the slosh effect to the stern when getting on plane, which makes it harder to get on plane.

Jason, you might as well just move that lead to the rear when surfing.

It does. Too much rear weight in the A22 will make the wake crazy wide, tall, and soft. If you run the stock pnp system, out of the box and the wedge, the boat is stern heavy, and you'll have a very wide wake.

I don't know what the front PNP sack weights, but I run that full, plus about 500/600 in lead in the nose. This is with 450s in the rear, stock tanks, and the wedge. I think that equates to about 50/50

Interesting. I've not seen that on the older hulls.

2315 should get 750s out of the hole, but you probably need 750 up front on the seats.

Maybe with the big motor. Maybe without the wedge. Otherwise, not even close. We already have 600 in lead up front. I don't think 150 pounds will make any difference. It may also depend on the mineral density of the water, temp, and depth. All factors for getting on plane. A boat running in cold brackish can probably pull them with the small motor.

Oh, yeah I completely brain farted. Definitely no wedge.

I really prefer it without the wedge and more ballast.

I have a 15' A22 with a 409 motor and a 2419 prop.

I currently run full tanks, wedge, 600s rear, 500 bow sac (not sure what it fills to), a 400 sac under the middle bow seat and 350 lbs of lead to move around on the cabin floor.

With 2-3 people in the boat this puts up a solid wake and wave.

I went with 450's, very glad I did.

Surf wake should be fine at 10.5. Wakeboard wake is enormous. It's a T, not an A though, so I would bet I get a lot more weight up front without extra sac's than you A22 guys do

Need more weight IMO. Running Bow sac, middle bow sac, 750's in the rear, 400 on seat up front. 400 on each of the side seats in back, wedge down, 1-3 people on boat. You absolutely have to balance out the weight front to back. You don't get enough up front the wake will wash out. My best advice is to borrow a bunch of 400lb bags and move them around and get the wake you want then buy what you need in the places you need.

Surf between 10.2-10.6. Make sure your carrying a stand alone GPS to check the speed as I've noticed some speed variance.

Without bow weight to offset the big rear load , wave won't form.
You don't need it to plane to surf so that fact is irrelevant to surfing.

My minimum set up in an a20

750s rear burped to full, say 650
Stock 800
Front 950 mushroom say 800
Fuel say min 300 after usage could be 400, my front sac leaks
So bilge water offsets fuel usage
Wedge
Wife batteries gear
Total 3500 plus wedges in a 20 ft boat, you have to sink it and offset the rears with
Lots of front
We surf 9.8 to 10.4
I could use 400 (2big dudes'in bow) more up front and wave would lengthen even more and would still be jacked up
Goofy awesome, regular real good , could be awsome with a little list moving the passengers around

Has anyone had trouble with the surf gates being too deep in the water and not creating a wave?

I had 8 people in the boat, 600s rear, 500 bow, 350 lead in bow, with the wedge and the wave would be super washed out, so I started draining the rear sacs, but then I couldn't the the wave height that I usually do and it seemed like I needed more rear weight.

I normally run full tanks, wedge, 600s rear, 500 bow sac, a 400 sac under the middle bow seat and 350 lbs of lead spread around with 2 people in the boat.
