Every summer, the world's largest concentration of superyachts migrates to the Mediterranean, cruising between hotspots such as St Tropez, Mallorca, Mykonos, Sardinia and the Amalfi Coast before many cross to the Caribbean for the winter season. From world debuts to famous charter yachts and iconic private vessels, BOAT International (with the help of its yacht spotters) is tracking the biggest superyacht sightings of the summer. Now we're giving our trusty readers the chance to feature on our platforms...

Queen Miri
Spotted between Son Parc and Arena Bay along Menorca’s rugged northern coast on 8 July, this 91.5-metre Grecian colossus and flagship vessel of Neorion boasts a top speed of 18 knots and cruising speed of 16 knots – powered by two MTU diesel engines. Queen Miri was designed by Alpha Marine and Bernd Weel Design, who fitted her with a fully certified helipad which, when desired, can be turned into a sunbathing or party deck.
Her interiors, designed by Massari Design, feature a 200-square-metre spa and gym complex, a conference room, a library, cinema and crystal light fixtures from Preciosa. She features 18 cabins, accommodating up to 36 guests and 34 crew members.
Althea
This well-loved yacht was spotted at anchor off the coast of St Tropez on 7 July. The 47.5-metre yacht Althea was built by Admiral – of The Italian Sea Group – in 2020 and more recently in 2025, she underwent a major technical refit; her machinery was refreshed and her systems updated. Gian Marco Campanino is credited with designing her interior and exterior, featuring a minimalist design in neutral colours, a sky-blue hull and expansive decks created with relaxing and entertaining in mind.
Child safety is a key USP of this vessel; her exterior is free of any sharp edges, and one guest cabin features a small cut-out door within the main bathroom door, ensuring a child can exit safely in case they get stuck inside. She can accommodate up to 11 guests across five cabins, with further provisions for a crew of seven.
Kaos
Once one of the largest superyachts built in the Netherlands, the 110.1-metre Oceanco Kaos was seen in Menorca’s Port Mahon on 2 July. Her generous 4523GT and 16.4-metre beam accommodate up to 32 guests across 15 cabins, with further space for 39 crew members. Muscovite Igor Lobanov is credited with designing her iconic mind-bending “floating island” illusion decks, the largest of which contains an 8.5-metre-long swimming pool, with Middle Eastern-inspired interiors by Reymond Langton Design.

BOAT’s eagle-eyed yacht enthusiasts spotted this Insta-worthy Italian motor yacht off the southwestern coastline of Mykonos on 16 June. Both the interior and exterior of 43.5-metre This Is It were built and designed by Tecnomar of The Italian Sea Group, which used glass panelling and asymmetric lines to give the client something totally unique. The brief also included child-friendly spaces; the Italian designers therefore included a convertible cabin on the main deck, which can be used as a child’s playroom, educational space or even a guest room for a nanny.
Yachting superfans may remember when songstress-turned-makeup mogul Rihanna enjoyed a trip on board during the 2025 Cannes Film Festival, accompanied by boyfriend A$AP Rocky. The small but mighty catamaran can house up to 12 guests in six cabins, with space for 12 crew.

On 12 June, the two-year-old sailing yacht was seen near Antiparos in Greece while preparing to compete in the Cyclades Cup. One of two wallywind110 yachts, the 33.4-metre Wally-built yacht can accommodate up to eight guests in four cabins, with five crew members. Interiors and exteriors were designed by Wally and Milan-based Santa Maria Magnolfi, who combined “quintessentially Wally” features with a design that promoted comfort, functionality and elegance.
A significant USP of Galma's interiors is the distinct lack of a lower-level lounge; instead, she features a “help-yourself” bar that has a coffee machine and egg maker – tapping into the emerging trend of choosing a self-serve function over silver service.
Lady Lucy
Spotted near Purobeach Illetas beach club in Mallorca on 21 May, the 39.8-metre motor yacht Lady Lucy is well-suited to long-range cruising, thanks to her displacement hull. She is a true Dutch affair; not only was she built by Heesen Yachts, but her naval architecture is also credited to Vripack, with exteriors by Omega Architects and interiors by Velendric Design.
Her upper deck features a canopy, Jacuzzi, eating area and wet bar on the sun deck. She can accommodate up to eight guests in four cabins, with space for seven crew members.
Vertigo
During the World Superyacht Awards on 1 May, the 67.2-metre sailing yacht Vertigo was papped near Giardini della Marinaressa in Venice. The flagship of Alloy Yachts, this vessel was named sailing yacht of the year at the 2012 World Superyacht Awards. Built with a teak deck, an aluminium hull and aluminium superstructure, she can accommodate up to 12 guests in five staterooms, with space for 12 crew members.
Naval architect and exterior designer Phillipe Briand described her as his toughest project due to her size (67.2 metres). Her arched coachroof is said to resemble a 21st century “pleasure dome”, as mentioned in Samuel Taylor Coleridge’s 18th century poem, Kubla Khan, Or, A Vision in a Dream: A Fragment.
