Flexible Water Tanks

Flexible Tank for Vancouver 34P

The flexible water tank in my Vancouver 34 has given up the ghost (leaking at the seams). It's a long t-shape, holding 220 litres. I've tried to find a replacement online but have drawn a blank. I'd be grateful for any advice, particularly if anyone's been down the same route.

If you can't find a similar shape off the shelf then talk to Duratank who will custom make you one.

I was thinking to supplement the stainless underfloor tank we have with a flexible tank, but my co-owner thinks they make the water taste plasticy.

Is it true? does the water taste bad?

I replaced Kindred Spirit's Plastimo flexible tank, and the hose, a few weeks ago. At first the water did taste quite plasticky, but I pumped a couple of bucketfuls through (didn't even empty the tank) and it now tastes of nothing at all. I think the hose, although meant for potable water, must have had some manufacturing residue in it at first. The tank doesn't appear to have tainted the water that has sat in it for weeks.

Although I always used to disapprove of flexible tanks, there's no practical alternative on KS. Now I have one, I've realised that for the price of a new Plastimo inner bladder I can regard it as a semi-consumable item. If stuff does start growing in the water system in a couple of years, rather than swilling Milton around the place and hoping it's OK, I can fit a new bladder and hose for complete peace of mind.

Ok too late to be of any real value.

We have 2 x 150 litre flexible tanks aft of centre, one in each hull, there is also another 250 litre tank in both the forward cabins. Seems the guy who sailed her from the USA to Oz was afraid he might die of thirst.

Both the aft flexible tanks have carpet tiles as a backing to soak up any condensate, this is important, I have seen a few flexible tanks cause blisters on the inside of the hull.

Oh, we have never used the forward tanks and plan to remove them, both are fibreglass and built onto the hulls, so some grinding to be done.

If/when the stern tanks fail I plan to build fibreglass tanks with baffles and access points on the top and filler points at the front of the cockpit. The construction use closed cell foam and the inside will be epoxy lined.

One final note, I would avoid adding weight to the bow, are you sure you have no space amidships?

Hi,

I replaced the tank in my 34P, the original manufacturing company was sold to a chap who is less than helpful, Northshore now use Hovercraft Consultants Ltd to make the Vancouver tanks, they have the drawings and made ours to order in about a week web site:

Had plastimo water bag on my boat.
Find with age they go brittle, and crack.(as mine did)..

I put new Plastimo liners in my water tanks soon after we got the boat in 2001. They split in 2008 and liners and outer bags were replaced again.

16 years with Plastimo tanks and no problems. Outside now getting brittle, but inside seems fine. Do have a problem with the filler hose connection that tends to leak. Seem good otherwise.
