It was the sideways movement the was the problem. When you put large weight on one side of the bottom rung it tried to move the other way. I got it sorted out ok in the end

The other thing I need is a tidy way of securing the tanks onboard. Have any of you got some pictures of how you do it ?

I have some space behind the driving seats lengthwise and imagine some sort of stainless steel work there where I can secure my two twinsets.

I can't understand why you folks put tanks in the back and people/coxwain/consoles up front. At least for me, the tanks can take the bumpier ride.

Here's my tank rack. I can try to take a closeup pic if yo'd like. It holds up to 8 tanks. There are tabs for looping a strap through every 9 inches. So 7.25" diameter tanks, 8" diameter tanks, and doubles/twins of either size (with standard manifodl spacing) can be strapped in. I redo the strap based on what I'm carrying on any given day.


A few more pics of my setup in the album

We stiffened it up through extra brackets on the new transom ! and has worked fine for the last 2 years, we do work with commercial divers using surface supplied equipment. no problems so far.
We also have a 9m ribcraft with a fold out version behind the console, this is fastened to the existing sockets (12) in the floor, and folds out over the tube

I thought of fitting a cylinder rack, I came to the conclusion that it would take up kitting up space. I lay twinsets/rebreathers in front of the console, they won't go anywhere!

My boat has the rack at the back and leaves plenty of space for kitting up for 4 people with rebreathers and 2 stages each. I don't want my rebreather rattling about in the bow so have it tied into the rack with stages on the end or on the floor. There are too many expensive dangly bits on my kit to just leave it on the floor.

If you only ever need two twinsets you could put a T shaped rack against the seats, that'll have minimal impact on kitting space.

This thread has made me think again about a ladder as I'm happy to take stages off in the water but handing quite a few Łk of rebreather always makes me nervous - even when clipped to a line.

More expensive shiny stuff...

Well I reckon as its just my wife and I diving, our twinsets will fit at the back of the driving seats. There is still plenty of space between them and the rear bench seats. I thought it would be best to have the weight at the rear rather than the front. The other issue is the shower will be at the rear and the front will have a table for lunch, so I reckon the rear is the best.

It is 8.5m long for just the two of us, so space is not an issue.

I may make a mock up with some wood and see what looks / works best before investing in a stainless version.

Im going to spend some more time googling for pictures to get ideas.

Trell, have you got a picture of the fold out one you mention ?

You could use the cylinder rack as the base for the table...
I'm considering a fold up top that will sit on the rack for days when we're out playing and not diving. I saw something similar years ago that worked really well. It was held in place with 4 small loops of bungee round the stainless tube.

I'm not sure I really need a shower... :-)
