IF-Sailboat and Fuel Cell motoryachts

Deodesk now tests boats on hydrogen

  • 200 Watt is sufficient to keep the battery of the electric motor under tension when sailing out and entering the port
  • Even for longer trips, the 200 Watt fuel cell is sufficient, provided that you sail with low engine power
  • At 3 Km / h the consumption drops from 126 Watt to 27 Watt (the limitation is not the fuel cell but the charger) and the range increases from 18.8 Km to 65.5 Km.
  • At 5 Km / h, consumption drops from 411 Watt to 316 Watt and the range increases from 9 Km to 14 Km.
  • During sailing, about an hour, the fuel cell charges 13% in the battery. That was spacious enough during the test to enter the port by motor

We test the fuel cell in combination with a 1.2 Kwh (KiloWatt hour) Lithium Iron Phosphate (LiFePO) battery. It weighs only 10Kg and is very compact. In addition, we use the Torqeedo 1003 C Travel, the long tail version. This has a built-in battery of 916 Watt hours. The new version of this engine is the 1103, which we warmly recommend. It is quieter and more efficient because it uses a DC motor. Our version works with an AC motor with delay transmission. Torqeedo outboards are strong, practical and offer many options such as GPS (standard), display on smartphone / tablet (option), charging while sailing, USB output (standard) and remote control (very practical with sailing boat!)

advantages of Lithium and LiFePO batteries:

  • Does not lose voltage and can deliver high power. 60 Ampere is no problem
  • Very light (10Kg)
  • Minimum voltage is 12 Volts, which prevents high amperages
  • No production of bang gas, which can occur with lead-acid batteries. (NB: hydrogen is NOT blow gas, blow gas is the ideal combination of oxygen and hydrogen)
  • Can be charged with both high current and low current. long-term trickle charging is no problem.

IF-Boat is now again being made brand new by Seacamper in Germany following the original design and specifications.

You sail for leisure, which is why you want silence and as little vibration, noise and emissions as possible from a diesel engine, which is often used to enter and leave the port, but also often runs for the power supply. This is not the case with this brand new IF boat. The motor is electric and is powered by a 2.5kWh battery and additionally by a hydrogen fuel cell.
