Curvelle Quaranta

Curvelle’s Quaranta was designed to challenge all the traditional standards of Yacht design.

It was designed to create 50% more interior space than similar length monohull. The spacious cabins have been designed to offer luxurious standers of comfort.  Every cabin is wonderfully light and airy and comes complete with fantastic views.

What’s more? The main deck includes a unique lifting platform/beach that lowers your personal submersible straight from the main deck into the water.

Mini-Sub Transporter

Complying with U-Boat Worx` specification, naval architect Cedric Adroin developed a "small craft"carrier boat aptly named the "Mini Sub Transporter". The resultant support vessel is able to transport passengers swiftly and comfortably out to sea to various dive locations, where the sub can then be launched and the dive sites explored. This concept is based on a catamaran hull connected to a versatile platform that can accommodate two of our models: The C-Quester and C-Explorer.

Deep Blue

The Deep blue by naval architect Cedric Ardoin is dedicated for day charters with limited crew requirements. However, this support vessel can still shelter 12 passengers from the rain and spray and accommodate all their diving equipment. Moreover, the choice of engines includes inboard diesel and class 4 water jet ensuring a 25 to 30 knots cruise speed. The large platform on the back for the C-Explorer submersibles is equipped with an articulated arm that can lower down the submersible when launching is required.

The Deep Blue can easily be personalized, by adding guests cabins, crew cabins or can be upgraded for the C-Explorer 5.

The Pontoon-Boat consists of aluminum pontoons and has a length of 12 meter.

The concept of this support vessel is that the submarine can sail into the rear end of the boat and can be lifted by a crane. Passengers can easily step in and out of the submarine due to the increased steps on both sides of the boat. While sailing to the perfect diving spot passengers can seat themselves on the deck and enjoy the trip.

Mondo Marine DEEP 51

The 51 meter motor yacht DEEP 51 is one of Mondo’s Marine newest projects.

As shown in the renders (please view the attachment) they designed a platform where the C-Quester 3 can be lifted from the water with a special cradle and that can be slid into the yacht. To launch the sub, the platform can tilt by which the sub gently slides into the water.

The Moonen M/Y Sofia

The 42 meter Sofia, is the biggest project from the Dutch shipyard Moonen so far and carries a C-Quester 3 onboard. The sub is launched with a unique crane system that is integrated in the swim platform. It is invisible to the eye; once the sub is removed, the area can be used as a swim platform that supports watersports.
