YS 5009

Naval architecture by DAMEN

The 55-metre YS 5009 (182 ft) has proven our most successful Yacht Support design to date, with 10 vessels delivered or in build. With each new build, we’ve set new standards – challenging ourselves with input from clients, crews and yacht managers to develop new yachting features that distinguish the YS 5009.

Private luxury submersibles offer a mesmerising way for all guests to enjoy the underwater world, go deeper and share unique experiences together. However, operating with conventional superyachts is logistically challenging at best and often impossible. With a YS 5009, submersible operations are completely separate from the mother yacht with the ultimate dive set-up for both scuba diving and submersibles – with the option of an A-frame launching system.

Custom configuration

  • Technically ready for stern A-frame installation
  • Aft adventure centre with wetsuit stores, dive compressors and EANx (Nitrox) facilities
  • Containerised modular dive equipment, decompression chamber for enhanced safety
  • Large dive support tenders
  • Reduced draught for operations in shallow waters
  • Divemaster/submersible pilot accommodation
  • ROV / submersible dive control room


The YS 5009 is the ideal companion to your superyacht, accommodating extra guests, staff or crew. You can use her for overflow guest accommodation from the mother yacht or for children’s accommodation. The cabins and the lounge area are quiet and comfortable with yacht-quality air-conditioning.

  • Accommodation for 8 guests in 4 cabins
  • Outdoor dining/lounge behind the wheelhouse (50 square metres / 538 sq ft)
  • Main Deck lounge (30 square metres / 323 sq ft) with 180-degree panoramic views
  • Large galley for fine dining and beach party set-up and support


Do you own a sailing yacht or enjoy chartering sailing yachts? A YS 5009 support yacht provides all the extra capability, including large tenders and helicopter operations, so your sailing yacht remains uncluttered and sleek. Live the nautical dream with all the gear, speed and space you need for the ultimate high-end sailing experience without compromise.

Custom configuration

  • Maximise luxury space – move crew facilities, cabins, laundry, etc off the yacht
  • Take all the tenders and toys you can’t fit on your sailing yacht
  • Keep spare parts, rigging and extra sail gear nearby, but not on board your yacht
  • Workshop for sail,composite, wood or metal repairs
  • Deck space and on board hoisting capacity for large masts
  • Store provisions, fuel, garbage and waste water for operating in zero-discharge zones (eg marine nature reserves)


The clear aft deck of the YS 5009 is the perfect spot to land a helicopter without concern of obstructions or loose furnishings. Safety first for your family and guests, who arrive and depart without annoying noise, salt spray, disruption and delay on the mother yacht. If you want safe helicopter operations night and day, underway and not only in calm conditions, our YS 5009 certified helideck is the solution.

Air support

  • Increase the operational envelope – no more flights postponed
  • Suitable for larger helicopters up to a take-off weight of 5 tonnes and a D-value of 14 metres
  • Full certification and firefighting capability
