📄 HOT TUB EBOAT
The Spacruzzi hot tub boat provides an exceptional fusion of relaxation and innovation, combining the comfort of a hot tub with the functionality of an electric-powered watercraft. Constructed with precision, the boat offers unique luxury experiences on lakes, harbours, and calm waterways.
Measuring 15.6 feet in length and 8.2 feet in width, the Spacruzzi comfortably accommodates up to six passengers. With a dry weight of 1,200 lbs and fully loaded weight of approximately 4,500 lbs (including passengers and 400 gallons of water), stability and smooth operation are ensured. Its shallow draft of only 2.75 feet allows easy navigation in shallow waters.

Powered by a quiet, emission-free 3.0 Torqeedo electric pod motor generating around 3-5 horsepower, the Spacruzzi achieves a leisurely cruising speed between 4-5 mph. The standard battery setup provides up to 4-5 hours of continuous use, with options to extend runtime up to 16 hours using additional battery packs. A fast-charging option is also available.
A propane-powered heating system maintains water temperatures up to 104°F, ensuring year-round comfort. An advanced, patent-pending internal filtration and circulation system keeps the water clean without reliance on harsh chemicals, while an at-dock chlorinator system supports hygiene maintenance through a light saline solution.
Built in Montana, the Spacruzzi features premium-quality synthetic teak decking or optional rubberized surfaces, along with a handcrafted powder-coated steel tower and awning for weather protection. Safety considerations include built-in compartments for secure storage of life jackets and safety equipment, compliance with U.S. Coast Guard specifications, and design elements ensuring boat stability under various conditions.
The Spacruzzi is now accepting reservations for its 2025 production cycle, with limited availability.

⚙️A BOAT OR A PLANE?
Regent Craft, headquartered in Rhode Island, is reshaping regional maritime travel with its innovative electric-powered Viceroy seaglider. Designed for high-speed coastal transportation, the Viceroy utilizes wing-in-ground-effect (WIG) technology, flying just above water surfaces to combine the efficiency of marine vessels with aircraft speed.
The Viceroy measures 55 feet in length, features a 65-foot wingspan, and comfortably carries 12 passengers alongside two crew members. Powered entirely by batteries, it reaches speeds up to 180 mph and can travel distances of approximately 180 miles per charge. This performance positions the seaglider as a compelling alternative to traditional ferries and short-haul flights, significantly reducing both emissions and operational costs.
The company’s development milestones include the successful flight of a quarter-scale prototype in 2022, providing critical data to validate aerodynamics, propulsion efficiency, and stability. Regent advanced rapidly from this prototype stage, unveiling a full-scale, passenger-capable seaglider named ‘Paladin’ in March 2025. Sea trials are currently ongoing in Narragansett Bay, Rhode Island, with human-operated flights anticipated later this year.

Regent aims to deliver the first commercial Viceroy models to customers between 2026 and 2027. Interest in this groundbreaking vessel is strong, with more than 600 pre-orders placed by prominent global airline and maritime operators, totaling over $9 billion. Notable early adopters include Brittany Ferries, Mesa Airlines, Mokulele Airlines, and other forward-looking transportation companies.

The GP 33 by GreenPower Boats delivers a sophisticated blend of eco-friendly technology and high-performance luxury in electric boating (appears to be renders at this point). This 10-meter electric boat, featuring a beam of 3 meters and a draught of 0.85 meters, stands out due to its innovative hydrofoil-supported, wave-piercing hull. This advanced design significantly reduces drag—by more than 50%—effectively doubling the vessel's range and offering enhanced stability.
Powered by dual 80 kW continuous electric motors with closed-circuit water cooling, the GP 33 is available with battery packs ranging from 132 kWh to 220 kWh. At a cruising speed of 18 knots, the vessel achieves an impressive range of 50 nautical miles, with a top speed reaching up to 22 knots. Its lightweight construction utilizes advanced composite materials, reducing overall weight without compromising strength or durability.
