Drinking water on a 22ft boat

[niCastro]

Hey there. My wife and I are doing a 30 day cruise around the San Juan islands this July. We are wanting to bring at least 20 gallons of water (more if we can) onto our US Yachts 22 but don't have good ideas on how to carry the water. This would be water for about 5-7 days for us using our well tested backpacking skills.

The normal 5 gallon jerry cans seem too big for the storage space under the cockpit and there just isn't deck space for them. We're thinking about maybe just using the 1-2 gallon disposable jugs and refilling those. It'll be a pain if we have to use the dinghy to get water but not so bad if we are at a dock and can use a hose. Just curious to hear what others have done on boats in the 22ft range and how much you were able to carry.

Thanks for any advice.
