Most people I know recommend the 10 liter MSR dromedarys. Easier and faster to load more water into the boat with 1 or 2 droms than carrying and packing several smaller water containers. Also makes refilling faster and easier.
I used to sea kayak guide for an outdoor expedition school, used the Dromedarys while guiding 3 week long trips in Baja, Patagonia, and Alaska. In Baja we carried a week’s worth of water with us, 3 10 liter dromedarys for the singles, and 5 gallon jugs in the center hatches of doubles with more droms stuffed wherever we could fit them. 1 gallon per person per day is a lot of water, boats are heavy after a re-ration and filling everything up, but the water gets used quickly and the boats lighten up. Never had a drom fail.
Just got back from a 10 day paddling trip in Maine, had two 10 liter dromedarys in my boat the entire trip.
The only way a drom is going to fail is if you forget to pack them and leave them on the beach.
Check them out, they’re a very good product. https://www.msrgear.com/water-treatment/storage-bags/dromedary-bags/dromedary-bags.html

Years ago Ed Gillette paddled solo from California to Hawaii. His experience is very interesting.
Not to be confused with Ned Gillette, world renowned adventurer who, though mostly recognized for mountaineering and ski expeditions, also took a rowboat he helped build himself across 600 miles of some of the roughest ocean in the world from the tip of South America to Antarctica in 1988.
I had the pleasure of meeting him in 1977 just after he and his team had skied across Canada’s Ellesmere Island. Super nice person – tragically, murdered by bandits while he and his wife were trekking in the mountains of Pakistan in 1998.
