I know we are not conserving water because I know we are usually within 5 hours or less from home where I can refill.
The one thing that stresses me out is what quality of water do you get? I can drive 10 minutes to the next town where the well is very different. It's heavy iron and sulpher. I even pulled into a slip on the Bay and was advised not to fill up since it's not the best water. I don't know. It seems as though unless you have some kind of water quaility chart per marina, then you may not know what you get. How do you deal with that? Any guidepoints would be great. Thanks.
You're using a little less than 10 gallons of water a day each. For some people that's a ton of water for others it's a normal amount for even others it's nowhere near enough. Be a bit leary of others that try to tell you how to ultra conserve water. I get the impression you enjoy having the water you need to be comfortable. You stated that you want to take an extended cruise
. Could you define a bit more what that means to you? Time, distance, areas covered, will you mainly be on the hook or will you stop at marinas
occasionally frequently etc. The quality of water from a boat based watermaker is better than any water you can buy. Even if that water you buy comes from an RO supplied system on shore. RO systems make great water, where that water is stored before you buy it is where the problems usually are. But that can be said about the condition of your boats fresh water tanks
as well. Anytime someone advises you not to fill up at a certain dock
I'd strongly suggest taking their advice. But, depending on your intended cruising grounds, many times good water can be found for free or at a small charge. I don't deal with it at all because I have a watermaker and only fill my tanks
water at my home dock where I know the condition of the water. With the right watermaker on board you shouldn't have to deal or worry about any dock water you encounter while out cruising. One fact of having a watermaker on board is that you will increase your usage. So if you are both using about 20 gallons a day it would not be unreasonable to suggest that you'll up that usage to 30 gallons a day. It's probably a good figure to start with especially if you have the occasional guest on board. A starting point for a watermaker would be one that would produce 400 gpd or about 16+gph. Running the unit every other day or every three days would be a starting point when considering which watermaker will fit your needs. You stated a forward tank of 55gallons, is there another tank on board?
