Absolutely, hence all the (good) advice to the OP to sort out the fundamental problem rather than trying to stick a plaster on it. Personally I don't think a water ballast tank is a good solution, it isn't fast enough (imo) to react in a tricky situation & wouldn't be a substitute for PTT. They are used to give semi-permanent trim to an un-balanced setup e.g when towing skiers or casualties, you would still use the PTT to fine tune or make quick alterations e.g turning into a following sea.

I have a dump/ballast tank in a Ring 18 speed/ski boat with a pick up and dump mechanism on it.

I have also had a Avon SR4 and I would never even think of putting anything like that in it.

The best advice is from Matt H. Mine was set up exactly the same and I had no issues with the handling.

Or just a more creative fuel tank shape/storage?

Get the biggest tank that fits in your console cost around £100 carry a spare 25 ltrs in the bow if needed.
your boat is built to be in balance with the engine and console set up as it is even manual tilt will sort a level plane.
My opinion but why do you want to carry sand/ water no help to you at all if you need weight carry fuel stick your kit in dry bags stick them in the bow.
Jack your boat up on the trailer in the middle shift kit around till you achieve equilibrium trim your engine two holes up and try that.
Leave the sand on the beach

Yep, Avon fuel bags, two of them fastened to the tubes and sitting in the joint between the tubes and the hull inside would be perfect, but I'm currently not able to afford that(I just bought Powertrim a few hours ago ) But it is on my list because it gives more deck space.

I'll see how it works out with PTT, and if that doesn't cure my problem, I will start moving fuel around. I wanted to avoid that because it would mean loosing a few comforts like a fuel gauge and a single fill tank (I'd need one under the console and one hidden away somewhere, possibly in front of the console where there isn't much space as well, the Anchor also lives up there..) but ultimately the rough-water handling is much more important(the handling isn't THAT bad, but it's still not perfect, and after all the equipment I carry around with me, I want it to be, else the time invested into that little boat would be a complete waste.)

We have a stainless tank lying around that came out of my sons sr4 which should fit in front of your console. It's triangular to fit in the bow you can just see it forward of the console in the picture
We've changed his console and won't be refitting the tank if you think it may be of use to you I can take some clearer pictures for you

Hey

If you could send me the dimensions and clearer pictures, once I'm home from my holidays I can tell you if it would fit.

Thanks

Thus leaving your stern light as it should be especially with out PTT.
SR4 's are small slim boats and don't take kindly stacking weight up on its arse!

If you want it to handle better, your going to have to move the fuel or counteract a 40kg problem dude


My thoughts exactly, besides how often would a little boat boat like that need 45 lt. A 20 lt fuel tank brought forward and a spare 10 lt can should last quite a while. I use 33 lt on 130 km trips with a 70 hp.

Actually I usually empty the 40l quite fast, back when I broke my fuel tank i was thinking about a 60L replacement.
Then again im currently usin 0.5 per km so its propably the prop and motor height(which i cant raise more because of the trim issues)

The 55 two stroke will drink far more than a 70 4 stroke and the range required is totally down to the users requirements so not realy for anyone else to say you have too much onboard. What's the saying "you only have too much fuel when your on fire"
Regardless of the ballance of the boat the power trim will transform the handling & ride so once the trims fitted then you can re-evaluate the ballance then
If required
