The term osmosis was originally used to describe the biological process whereby a liquid (usually water) will pass through a semi-permeable membrane. The membrane is permeable to the water molecules but not the various compounds dissolved within the water. The overall flow of the water molecules will be from the solution of lowest concentration towards the solution of higher concentration. The Osmosis is the tendency of fluid substances, if separated by a porous membrane to filter through it and become equally diffused. Generally, when you lift your boat up on a shipyard, you see small bubbles forming on the bottom of the hull (sometimes even above the waterline), it is usually water absorption under the gelcoat of the boat and sometimes into the fibreglass. The osmosis is almost a fiber cancer, and if we don´t treat it, this problem will contaminate all the fibers of the bottom of your boat. We are at this moment developing this area and we have invested money and time to protect your boat from this serious problem the best way possible.


The boat will be inspected weekly, checking:

  • Mooring ropes check-up

Whatever type of boat you own, you deserve the unbeatable comfort and luxury of a climate system. Tecni – Marine is expert in installing air conditioning systems with minimum disruption to your boat. Skilled and experienced tradesmen sympathetically fit controls and grills, which are cleverly concealed within the design of your boat. Reverse cycle units give true climate control. Stay cool in the summer and keep you boat warm and dry in the winter using automatic dehumidification to protect expensive fabrics and upholstery. The addition of digital controls will give total control to within a few degrees.

Bottom fouling results from 3 primary causes: Marine Life, Plants and Algae slime. Anti-fouling bottom paintings are an essential part in the maintenance of your yacht. We carry out a precise inspection of all yachts so as to get a clear picture of the state of the bottom of each vessel. We work with two types of paint: Hempel and Nautix – Painting Specialist The basic of the application is the preparation of the bottom and we respect the healing time of each coat of paint. We inform our clients and friends that is better to loose another day with the drying of the paint than to rush the job and ruin the paint job which has been carried out, so be patient and give your boatyard the time to carry out the job well done. Needless to say, the general rule is that the more expensive the material, the slower it deteriorates, whereas cheaper materials deteriorate more rapidly. Anti-fouling bottom paint can help keep your boat’s hull in good condition, prevent barnacle attachment and algae growth, and will help your boat move through the water faster and more efficiently.

Keep your Boat Clean

A key step in maintaining your boat is to wash it regularly. Cleaning your boat regularly doesn’t only contribute to the looks of the boat, but also helps to protect your boat from the environmental conditions.  Also, wax your boat regularly to further protect the surfaces from the elements.

Regular Overall Inspection

Boats require regular inspection, as that is the only way to identify any problems or potential problems. Tecni-Marine can routinely check your boat’s controls, engine, cables, rudder, and throttle.

Bilge Pump

Don’t forget to check that your bilge pump is working properly. In case you do need to use your pump, you may need enough power to run it for an extended period of time. Make sure your battery system can support this. Tecni-Marine can help you on this matter.

Proper Mooring

Boats don’t only sustain scratches and dings from being used out on the water. Damage can appear on your boat’s body while docked if it is not moored properly. Make sure all lines are fastened securely and don’t show signs of wear or breakage.

Motor Maintenance

Flush your engine after every use. Check fuel tanks and clamps for rust, damage or corrosion. Check the engine’s oil levels and cleanliness. Also keep an eye on your boat’s cooling system to ensure that it is working properly. If you are not able to this by yourself, Teci-Marine can help you.

Electrical Systems

Keeping all of your boat’s electrical systems clean, dry and free from damage is crucial to the overall safety and well-being of your boat. Look for any signs of corrosion, and apply water-repellant grease protector to all fittings.

Battery Care

Check your battery regularly by inspecting its charge and fluid levels. Make sure that the area around your battery is clean and dry at all times.Tecni-Marine is available to this for you.


To protect your boat during the months that it’s not actively in use, you must take the proper winterization steps. Whether you are able to store your boat under shelter or not.  If you are not familiar with what needs to be done to winterize your boat, ask advisement to Tecni-Marine.

Boat Covers

Investing in a boat cover can prevent much damage that can occur as a result of exposure to UV rays and the elements. Consider picking up a used boat cover, you can save some money and extend the life of your boat.
