American House of Yachts

Where Timeless Design Meets Advanced Innovation.
The Spaceline 88T, an embodiment of elegance and engineering excellence.
Building upon the robust technical platform of the Spaceline 88, this model showcases the future of superyacht construction, moving beyond conventional composite, GRP, and plastic-built mass series boats.
This version, featuring a sleek design without balconies as an example (balconies are still possible), offers nearly 240 sqm of luxurious guest interior space. Enjoy the unmatched benefits of a 100-meter monohull yacht (all cabins are very large and all on main deck, very large ceiling height, super king size beds, Roof top exhaust, full beam bridge with Captains behind, enhanced by an electrified propulsion system complete with solar panels and batteries, designed with safety in mind—no risk of self-ignition! The solar panels are enough to have nearly no costs in Marinas and fully electric at anchor, a small generator only needs to run once a day for a short time. It is even possible to do limited trips only with electric power.
Key systems are fully redundant, and the hull provides expansive crew quarters and a crew mess and a generous storage and service area, making global exploration a reality.
Upgrades to fuel cell technology are available, as well as extending the range to 3,500 nm (at 12 knots) or beyond. Thanks to the more than 5 meters high bow, she is able to withstand very bad weather.

As always, every superyacht is delivered with a unique, bespoke interior design, tailored to your personal taste.

Summary of our main USP´s
- Aluminium Construction, with a frame spacing of only 50cm
- Most modern and efficient hybrid propulsion with generator exhaust on the rof-top and not at the waterline. Solar cells and battery packs included for a full electric and fume free experience
- Largest guest cabins on the market (25sqm to 30sqm), guest cabins all on the maindeck and all guest cabins can feature a private balcony
- Free ceiling height is at least 220 cm, “NBA player proof”
- Largest beds on the market with 200cm X 220cm, again “NBA player proof”
- Much lower operational and 70% lower fuel cost then a monohull superyacht with the same guest interior space
- Very high stability and capable to cross the oceans on own keel
- Fully enclosed Bridge with a Captains cabin behind. Therefore, full privacy for the guests as there is no helm station in the guest areas
- The interior and exterior layout and interior design is fully customisable to the clients wishes. Each Catamaran will be unique
- Because of the electric propulsion and spare space, all Catamarans can be upgraded to fuel cell technology
- Our shipyard , ISKRA in Sibenik / Croatia, has already delivered more than 130 Alu Catamarans and they deliver north European quality.
Value comparison to Monohull Superyachts:
SPACELINE 88:
Comparable Guest Interior space (225sqm to 240sqm) is equal to a 45 meter Alu Superyacht, Sales value min 35 Mill Euro plus
