HOIA 100 is a 30.50 m (100 ft) motor-yacht design by Franco Gnessi / DYD, shown in the MY 2026-02 brochure package. Its broad 8.20 m beam supports a layered arrangement of exterior lounges, a forward owner’s suite on the main deck and separate guest accommodation below.
The concept
The designer’s renderings pair a compact, upright profile with substantial outdoor living space. The foredeck is shown in different leisure configurations, including dining and a pool, while the upper terraces offer shaded seating and open-air entertaining.
Life aboard and deck arrangement
-
Main deck: saloon with dining for ten, a separate galley, day head and a forward owner's suite with its own bathroom.
-
Lower deck: two double and two twin guest cabins, each with an en-suite bathroom; two forward single-berth crew cabins, crew mess/kitchenette, machinery space and concealed aft tender storage.
-
Upper level: wheelhouse, lounge with a bar, day head, exterior terraces and a separate single-berth space with a shower room beside the wheelhouse.
The proposed layout provides ten overnight guest berths in five en-suite cabins, including the owner's suite; this is not a certified day-passenger limit. The brochure lists two crew cabins, while the upper plan also shows a separate single berth, so the final crew complement needs confirmation.
The concealed tender system
A dedicated concept diagram explains the aft tender garage: deck lids open to expose the stowed tender and its launch arrangement, then close to restore the deck surface. Both the technical diagram and the rendered open-deck arrangements are retained for review, rather than replaced with generic imagery.
Propulsion and range
The designer lists twin IPS40 propulsion with 3,000 kW total output, three Volvo D13 generators and a proposed thirty-minute full-electric mode. Design targets are 16 knots maximum, 14 knots cruising and a 3,500-nautical-mile range at 10 knots. The generator row also reads 3,000 kW, but does not make clear whether this is a combined rating or a specification error, so no generator power rating is claimed. These are proposed design figures, not sea-trial results.

Drawings and source package
Original elevation, general-arrangement, specification and tender-system sheets are provided in the dedicated drawing sections below, separate from the photo gallery. Snow and fjord settings are artistic concept scenes; they do not establish ice-class certification or polar operating capability.

Project status
This is an unbuilt design project, not an available finished yacht. Shipyard appointment, final engineering, classification, equipment, contract price and delivery schedule remain subject to confirmation. Performance and range figures, where stated, are designer targets rather than sea-trial results.
Images: photorealistic renderings based on the design studies by Arch. Franco Gnessi / DYD. This yacht has not yet been built, so these are not photographs of a finished vessel. Original technical drawings are shown separately; rendered equipment and layouts remain subject to the final build specification.
