A named series, with vessel-specific dimensions
Its opening-roof lounge and low outline distinguish it from a flybridge design. Published examples include three- and four-cabin arrangements.
The Corsican operator reference used here lists 21.60 metres by 5.40 metres; these are that yacht’s reported dimensions. Keeping the example explicit is more useful than turning a variable operator listing into a universal manufacturer specification.
Let the roof change the atmosphere
An opening roof changes how the main lounge feels during a quiet stop, without turning the yacht into a completely exposed cockpit. It can bring the party together around a sheltered seating area while retaining a view of the sky. The foredeck offers a separate sun area and the aft cockpit another place to sit near the stern. Decide whether your group mainly wants to stay together or would value those different spaces during the afternoon.
Choose the harbour moment and the coastal pause
A Bonifacio day can begin with the sheltered harbour, continue past the cliffs and settle into a suitable place outside. Keeping one longer pause gives the group time to enjoy the deck arrangement instead of repeatedly preparing for the next passage. If a meal ashore is important, flag it early. The landing or transfer plan should fit the actual yacht and local conditions, with enough time left for an unhurried return.
Look closely at the accommodation plan
Three and four cabins support different sleeping arrangements; the badge alone cannot settle who gets which room. For an overnight request, compare fixed beds, any twin room and the position of bathrooms. For a day, the lower deck may matter mainly for changing and a private rest.
Discuss steps and movement between spaces if anyone needs assistance. Current photographs are particularly useful for older yachts whose upholstery, finishes and equipment may have changed through refit.
Keep the enquiry centred on the layout
If the opening-roof lounge is the reason for choosing this model, make that preference explicit. Add the date, party size, time available and whether the experience should focus on lunch, swimming or a coastal passage. A comparable hardtop yacht can then be assessed against the same priorities. The final proposal identifies the actual vessel and its operating arrangements; the model guide helps establish what your group wants from the space.
Charter questions
Is 21 Open simply a made-up length label?
No. GC 21 Open appears as a model in the ICNN certification register, and direct brokers document the 21 Open or 2100 Open series.
Why are the dimensions labelled as operator references?
Published examples differ in length and layout. The figures here identify their source instead of presenting one vessel’s details as a universal factory specification.
