Heesen’s Ultra G was delivered to its owners on 29 March 2024, and is a pretty powerful superyacht with an innovative new rescue buoy. Read on for more details!

What’s This Rescue Buoy?

If anyone goes overboard, this rescue buoy (designed by U Safe) can cruise to that person up to 1,640 feet away. This is opposed to bobbing on the water like a traditional life ring does!

Some details about it…

  • U-shaped
  • powered by twin water jets
  • weighs about 30 pounds
  • top speed of roughly 9 mph (8 nautical miles)
  • can transport up to 2 individuals

Also, it is able to be actively steered by remote control. This means that crew is able to use it quickly, and the individual overboard doesn’t need to swim to reach help.

Ultra G’s Interior & Exterior


Frank Laupman’s Omega Architects handled the exterior design.

Ultra G‘s has an array of interesting features:

  • waterjet propulsion (this drives the draft to less than 3m and also aids in reducing vibrations)
  • lightweight aluminium Fast Displacement Hull Form. This comes with gyro stabilisers, course fins, and interceptor trim plates
  • engines are compliant with IMO Tier III regulations
  • a custom tender built by Vanquish to a design by Guido de Groot to mirror the mothership “down to the last brushstroke”
  • dog-friendly features including a “relief area” (this was included in the plans when she was initially commissioned)

The 918GT interior includes space for ten guests in four cabins on the lower deck. Reserved for the owner’s accommodation, the bridge deck includes large aft-facing cabins which open onto a private terrace – with a Jacuzzi and relaxation area.

Entertaining is an integral aspect of Ultra G‘s design. There is:

  • games table on the main deck forward
  • a sundeck with an infinity pool facing aft
  • a custom wine fridge in the main saloon
  • large media room with the latest audio-visual equipment
