no no... a monster watermaker will solve that issue... they produce amazing amounts of water...

I heard once about a sailor who got stuck in shallow water and he just cranked on his genset and turned on the watermaker and filled up the area around the hull enough to float it!

Sara,

Would that work for sailors who are not blonde?

( If you run the engines for any length of time the water will be that hot anyway) This enables her to mix a very small amount of superheated water with a large amount of cold water to last 15 minutes at 105-110. You just want to be careful and not accidently scald yourself. You don't want to end up like that lady who spilled a 32 ounce supersized 180 degree cup of joe on her crotch at MacDonald's a few years back.

Also, with a 40 psi system, I don't think I get anywhere near 2.5 gpm, so even at full blast you shouldn't use more than 20 gallons a shower. LIVE IT UP! YOU ONLY GO AROUND ONCE IN LIFE!
By all means, its just natural resources we are using up at an unsustainable rate! In case you missed it there is a worldwide shortage of fresh water and it getting worse.

We have a propane on demand Bosch ventless water heater. It will make all the water you can supply hot. The ventless aspect dries the shower out quicker even in cold weather. You do need propane and the water to begin with so it's not totally unlimited. My brother in law got rid of twin 40 gallon tanks at his house and cut his propane use a lot. I would do the same at our house when my tank dies. Just storing hot water seems a waste. The on demand aspect maximizes efficient propane use.

For heating water unless you use a bag shower you are better off using solar to make electricity for cold beer. Electric based water heating is not all that efficient given refrigeration really needs the electricity.

I still live at home near Montreal and I already use less water than most people do. I simply turn off the water while applying shampoo, conditionner and body gel.

I have been trying to convince my husband to use that method for years now but he just won't do it. He better change his mind when we'll move on a catamaran.

Another thing, if you are in the Caribbeans, do you really need to take a hot shower? When I was in Barbados on vacations in a condo a few years ago, I almost always did not use any hot water, not even to wash the dishes. The "cold" water was hot enough for me.

At home we have a 40 gallons hot water tank and it is quite enough.

Here in Thailand, we heat some for dishes but use very little for bathing. During the dry season (the hottest) I never use any. You take showers to cool off as much as wash.

I can safely say that cruising will be wonderful for you

No matter what your solution to brewing 40 gals of hot per day, I can garantee you that after a while you will be down to much shorter showers. 5 minutes is a great number and fits exactly with the capacity of your hot water tank of 5 gals: 5 gals hot mixed with 5 gals cold = one 5 min shower


Wouldn't I love a 5 min shower!!!!!!!!!

With 15 minute showers he is going to need a lot bigger hot water heater than the normal 10-13 gallon ones installed on an average mid-sized boat. Maybe two of them. And unlimited hot water should not be a problem as he will be running the generator or engine for most of the day just to keep the watermaker working to refill the tanks.
- - I am sure the experienced cruisers almost fell on the floor giggling with the OP's question. Only because water consumption on a cruising boat is right up there with electric energy consumption as the two most radical differences between life on land and live on a cruising boat.
- - After being anchored in Luperon harbor, Dominican Republic for about 6 months a group of about 12 cruisers signed up for a tour up to Pico Duarte, the 10K ft mountain for some cool temperatures and white water rafting. It was an over-nighter so we stopped at the mountain lodge and proceeded to our rooms promising to gather for dinner in an hour. Almost to the minute an hour later we got together and everybody had ear to ear grins. Each of us had spent nearly a half hour standing in the showers letting endless hot water cascade over our water starved skin. The rest of the tour experience was great but after returning to the boats - all we could talk about was being able to stand in a hot shower forever . . .
- - Bottom line - don't expect to transfer all of your shoreside habits to life on a cruising vessel unless you have one of those super mega-yachts.

Are you looking at living aboard in a marina? If so, then use their showers. That is what every other live aboard at our marina does. Problem solved.

LOL We have never been in a marina since we left the Caribbean 27,000nms ago which has a shower, or working shower.

In all the hotels we have stayed at on our land travels only 1 (ONE!) has had a working hot water shower first up... the rest either none, not hot, or had to move rooms etc.

And 1 bath .... (brown water!)

I would have been on osirissail's mountain walk for sure!!

Boat showers. Water, soap, water. Use castile soap and you can do it in under 2 minutes.
