Flexible water tanks, not 168 litres

My surveyor says my tanks are excessively large! What would be the appropriate capacity for a 30footer planned for weekend and occasional 4-5 day trips for 3-4 adults? Wash basin and galley.
 
On my last boat - a 30 footer we had two flexible tanks - 100 litres each.

More than adequate for two adults for about a weeks cruising with occassional top-ups if needed.

Depends where you tie up. In marinas - no problem - bit different up the west coast of scotland. Sometimes nearest water is burns.

Really depends what you use the water for, and whether you have electric or manual pumps.

We carry 140 litres, have a pressurised pumping system, and can easily get through that in a day if all (2 adults & 2 children) have a shower, washing up after three meals, plus other cooking needs.

Manual pumps greatly reduce water consumption though!
 
we have pressurised water, but surely if you require a sink full of water for washing up it won't make any difference wheather it is manual or pressurised!?
 
With respect to your surveyor but that surely is a comment rather than advice to change them? The Liz 30 tanks I had were sausage flexibles under each main cabin bunk taking pretty well all the space under each, although a spare Danforth anchor did sit under one, protected by a bit of carpet from chafing the tank. One tank fed the galley via an in-line Whale electric pump (not a pressure pump) with a simple switch, the other fed the loo washbasin. Having the two tanks separated was useful as there was a spare when the first ran out, I can't remember if we washed more than we drank or vice versa though. Having plenty of capacity is a bonus IMO, it certainly was when we had our Liz and access to water as we were on a swinging mooring and anchored when away (fewer marinas anyway then) was less easy. You don't have to have them full if it bothers you or Mr Pernickety.
 
It really depends whether you put the plug in or not.

E.g. Cleaning your teeth - a couple of pumps on a foot pump as opposed to a couple of pints from a pressurised tap.

Harlequin has 2 x 100gallon tanks, one on either side (~440 litres) on a 37' boat. It lasts for ages though (unless SWMBO has a shower /forums/images/graemlins/grin.gif)
