Bilge Pumps

Bilge pumps are the first and last line of defense when water starts entering a boat. Maringret has 4 levels.

Whether the crew is on or off board, water coming into a boat can have swift and disastrous results. We had a split seacock drain hose which let water into the Maxi, we didn’t need to go through that again.

Maringret has 4 levels of electrical or mechanical bilge pump evacuation including a manual bilge pump.

XYZ pump

  • xx litres per second
  • float activated (separate float)
  • electrical
  • drains into starboard cockpit drain

This is the initial line of defense

Johnson XYZ pump

  • xx litres per second
  • float activated (built in float)
  • electrical
  • drains into starboard cockpit drain

This bilge pump is a second line of defense in case the primary bilge pump either fails or is overwhelmed. It is mounted a good 25 cm above the intake and float for the primary bilge pump.

Engine water intake

  • xx litres per second
  • manually activated
  • diesel powered
  • drains into engine exhaust

Should the other two bilge pumps fail, or if the electrical system fails while the  engine is running we can  manually direct the engine cooling water intake to the bilge (with a strainer on it) to evacuate the bilges. This is a method of last resort.

Manual bilge pump

  • xx litres per second
  • manually operated
  • drains into starboard cockpit drain

This bilge pump exists in parallel to the other 3. It can be operated from the cockpit at any time.

We had hoped to fit one of the prop-shaft mounted “emergency bilge pumps” but the bilges were to narrow to fit it. The amount of water it moves is staggering and would handle quite a large leak.
