I have always maintained that one can (must) live as well on a cruising yacht as he can onshore.
That ethic includes HOT SHOWERS.
There is nothing much better after a big day's sailing when one has been frazzled by the sun or encrusted with salt from sea spray than to have a hot shower.
Many think that is a luxury reserved for Fancy Forty Footers and bigger. Not so.
Hot Showers are a luxury that is affordable to even the most common of folk and 5 litres of warm to hot water is all that is needed to achieve it.
It is the delivery system that counts and this is one of the best I have seen.
