After outboards and pod drives, the I-20 is the first shaft drive motor for the manufacturer ePropulsion. With an output of 20 kW at 1,500 rpm, it is suitable for displacers weighing up to ten tonnes. It weighs 45 kilograms, is water-cooled, waterproof (IP67), is operated with a voltage of 96 volts and costs 9,999 euros.
Rad Propulsion has developed an electric outboard motor with an output of 40 kilowatts (equivalent to 55 hp). This can not only power motorboats, but should also be of interest for catamarans: The compact design allows the motor to be folded up without the need for a cut-out in the transom. Power supply with 400 volts, weight 100 kilograms.
International presents B-Free Explore, a biocide-free foul-release system. The coating is based on silicone polymer technology and creates a very smooth surface on which no fouling can take hold. The coating can also be applied to conventional antifoulings and is designed to protect against fouling for two years.
Clear Foul Release from Hull Maxx in the USA promises reduced infestation with smallpox and other marine organisms without the use of poison. It is said to be easy to apply using a sponge and can also be applied over existing antifouling. One can contains 946 millilitres for ten square metres of hull and costs 1,060 euros.
