Antonini Navi has delivered Seamore 34, a 112-foot full-custom steel crossover yacht that represents a significant step for the La Spezia-based builder. Developed on a steel-and-aluminum platform conceived in-house, the yacht was designed by Hydro Tec, with interiors by Milan-based Hot Lab.
Seamore 34 is the first yacht design from Antonini Navi’s new platform, which is intended to provide a foundation for future semi-custom projects while allowing substantial owner-specific customization. Its crossover profile takes cues from commercial and naval craft, including tugboats, fishing vessels and military ships. A vertical bow, reverse-raked bridge windows and pronounced bridge wings give the yacht a purposeful appearance.
Pre-delivery sea trials produced a cruising speed of 10 knots, a top speed of 14 knots and a range of more than 4,300 nautical miles. Noise and vibration measurements were also notably low, with 39.2 dB recorded in the owner’s suite while at anchor with onboard systems operating.
The interior layout emphasizes the connection between indoor and outdoor spaces, with more than 1,615 square feet of usable main-deck space and roughly 1,722 square feet of outdoor area on the upper deck. Hot Lab combined teak, pastel tones and ribbed surfaces to create a contemporary interior with a lighter, more residential feel.
Seamore 34’s delivery comes as Antonini Navi continues to expand its yachtbuilding operation. The builder is preparing to launch the 102-foot custom steel yacht Evo 31, while another 131-foot steel yacht is under construction on spec for delivery in 2028.
