Flexi bag tanks

[cherod]

fitted Plastimo flexi bag water tanks, 150 ltr / 30 gl , one in each hull , just wondering what the accepted method is , do you just let them contact with the bare fibre glass hull or do you fit some thing between, eg , piece of carpet, piece of plywood , foam yoga mat ( ) or whatever , i guess having them direct contact may help keep the water cool but maybe there are some friction issues to be considered , the ones that i replaced had been in for many years , they were direct contact and did not show any signs of damage , all opinions welcome, t y R

Bit of carpet won’t hurt, in case you have some sharp bits poking up from the grp.

I have 2, port & starboard and they just lie directly on the hull. I did consider carpet but think that it will just get damp and manky. I sanded and flow coated the hull where they lie to try and avoid abrasion but not sure it was necessary. I've had them for 19 years, had one split about 10 years ago but probably from over enthusiastic cleaning. A new liner was fairly cheap.

Cheap polypropylene carpet which conforms to hull shape, drains easily, does not rot., is light in weight, and cuts to shape easily and the edges can be sealed with gas light to stop unravelling. Also can be pressure washed. What's not to like ?

I bought one similar to these:-

Works a treat

We used roll-mat type foam and spray glue , is it called 'closed cell'?

I used a piece of cheap "astro turf" - plastic grass from the hardware store. Cheap as chips as long as you don't buy the expensive stuff. Anything that stops it chafing, has air gaps and will not retain moisture will probably do. 2.95 euro per sq metre from Leroy merlin (B&Q lookalike) here in Portugal. Available in your local equivalent store wherever you are I would think.

It helps to use the corner fixings of the outer bag to restrain the tank from moving about.

I used a form of astroturf. Managed to buy a large offcut at a local scrap store. Does the job really well
