Water tanks

Boat water tanks are a fundamental component for ensuring a reliable water supply on board. Whether it's a short day trip or a long-term cruise, having a dependable tank is crucial for personal hygiene, meal preparation, and overall comfort.

The tanks you find in this section are manufactured by Osculati, a leader in nautical accessories, and are made with high-quality materials certified for contact with potable water. The range includes rigid tanks of various shapes and sizes to suit any type of boat and available space.

How to Choose the Right Water Tank for Your Boat

Choosing the right water tank depends on several factors, including:

* **Capacity:** Calculate your water needs based on the number of people on board and the typical duration of your trips. Also, consider the use of showers, sinks, and other water-consuming devices.
* **Dimensions:** Carefully measure the available space on board and choose a tank that fits without compromising functionality and safety.
* **Material:** Opt for tanks made of impact-resistant, corrosion-resistant, and high-temperature-resistant materials. Osculati tanks are made of non-toxic linear polyethylene, an ideal material for marine use.
* **Accessories:** Check the availability of accessories such as filling necks, vents, level indicators, and pumps to facilitate filling, emptying, and monitoring the water reservoir.

Don't neglect tank maintenance: clean it regularly with specific products to prevent the formation of algae and bacteria.

How do I calculate the water tank capacity needed for my boat?

Consider the number of people on board, the typical duration of your trips, and the use of showers, sinks, and other water-consuming devices. In general, an average of 20-30 liters per person per day is recommended.

What are the most suitable materials for a potable water tank?

The most common materials are non-toxic linear polyethylene (such as that used in Osculati tanks) and AISI 316 stainless steel. Both are corrosion-resistant and suitable for contact with potable water.

How can I clean and disinfect my boat's water tank?

Completely empty the water reservoir and clean it with a solution of water and bleach (1 part bleach to 10 parts water). Let it act for at least an hour, then rinse thoroughly with clean water. Use specific products for cleaning nautical tanks to remove algae and bacteria.

Can I install a flexible tank instead of a rigid one?

Yes, flexible tanks are a good option if you have limited space on board. Make sure they are made of durable materials suitable for marine use and are installed in a location protected from bumps and abrasions.

What should I do if the water in the tank has a bad odor or taste?

Completely empty the water tank, clean and disinfect it as described above. Also check for algae or bacteria in the pipes and fittings. If the problem persists, you may need to replace the tank or consult a professional.
