Water tank

Hello Monsuns family.
I want to expose a problem with my water tank.
Depending of the kind of sailing my HR Monsun 674 (1979) I could find litle links of water at the bilge or the water tank completely empty, depending of heeling's level.
Finally, last week-end I toke out the tank and I found the walls fulls of cracks. After a bad movement I did a real hole and finally I discovered that the tank has arrived to the end of his life (38 years old)
It was a 160 litrs water tank lokated as ussual in the bow of the boat.
Looking here and ther in Internet I found this danish web page:
http://www.cipax.com/rotational_moulding_1/marine/water_tanks_2/water-tank-170-litres
They produce a similar water tank 1030x960x45. It is a 170 litrs.
My question is ¿anybody has the same problem? ¿Any ideas?
Thanks from Palma de Mallorca
Best regards
Juan Fuster

Hello!

Did you figure this out? If my tank ever failed, I think I would probably just use jerry-cans, and make it so that I could just attach the foot-pump in the jerry-can, and changi it out every time it was empty. In that way, it would be very easy to know how much water you had, and also to be sure the water was not contaminated (I drink a lot of collected rain water).

Hola Juan
I'm thinking about ordering made to measure tanks in SS and install them beneath the bunks in the saloon. I think the centered weight could hopefully improve the sailing abilities.
The project is still in a planning process. So, if anybody has ideas or experiences on that I´d be happy to read/see them.
Thanks in advance and have a nice sailing summer!

A low cost alternative would be water bags, aka flexible water tanks. Plastimo makes these, but probably there are other brands with different sizes.

Hi Albertina,
I also thought about tis but prefer a fix tank version - though more expensive :-(. Regards
