Article summary

REGENT has secured $240 million in Series B funding to support the transition to full-scale manufacturing of its all-electric Seaglider vessels. The Seaglider is designed for fast, safe, and zero-emission coastal transportation, with a top speed of 180mph and a range of 180 miles. The vessel combines the high speed of an aircraft with the convenience of a boat, operating exclusively over water on its hull, hydrofoils, or wings. REGENT has customers, investors, and partners across leading ferry, airline, and logistics companies worldwide.

What commenters say

  • The Seaglider's high speed and limited maneuverability raise concerns about its ability to avoid collisions with other vessels, particularly sailboats.
  • The rules of the sea and right-of-way regulations would apply to the Seaglider, requiring it to yield to sailboats and other vessels in certain situations.
  • The use of radar, AIS, and computer vision systems could help the Seaglider detect and avoid other vessels, but may not be sufficient in all situations.
  • The Seaglider's operating limitations, including its inability to climb out of ground effect, could make it difficult to operate in certain weather conditions or avoid obstacles.
  • The Seaglider's speed and noise level could pose a risk to recreational boating and other water activities.
  • The vessel's design and operation may need to be adapted to accommodate the presence of other vessels and water users.
  • The Seaglider's potential benefits, including its zero-emission propulsion and high speed, may outweigh its limitations and risks.
  • The Seaglider's suitability for different types of operations, such as ferry services or tourist operations, may depend on various factors, including weather conditions and water traffic.
  • The Seaglider's ability to switch between different modes of operation, including hull, hydrofoil, and flight, could help it navigate challenging conditions.
