An Excess 12 charter Kos week starts in Marina Kos, ten minutes from the castle and an hour under sail from the Turkish shore: a 2020 hull from the Beneteau group’s performance-cruising yard, eleven metres seventy-three on deck and six metres fifty-nine across the beam, with four double cabins, four heads and twin helms set aft where a sailor expects to find them. Bimini, solar panels and an inverter are aboard, and the charter pack covers linen, towels and the transit log.
A full-batten mainsail and a self-tacking jib make the Dodecanese easy to work with two hands on deck, and a light ten-tonne displacement means she moves in the eight knots of breeze that leave heavier catamarans motoring. Aquinox arranges this Excess 12 charter Kos the way guests actually want a catamaran arranged: provisioned before arrival, skippered if you wish, and routed so every evening ends somewhere worth waking up in.

An Excess 12 charter Kos booking puts you on the boat that gave the range its reputation. The helms sit outboard and aft rather than up on a flybridge, so the person steering is in the cockpit with everyone else and can see both bows and the sail at once. The mast is stepped further aft than on a conventional cruising cat, which moves sail area into a larger, flatter-cut mainsail and makes the rig noticeably livelier upwind.
Twin forty-five horsepower diesels on saildrives push her at cruising speed in a flat calm, and four hundred and forty litres of fuel with six hundred of water give a real week between fills. Steps from each transom drop straight to the water, which matters more than any brochure feature at four in the afternoon.

From Marina Kos an Excess 12 charter Kos itinerary usually runs south: Kalymnos for the sponge harbour at Pothia, Leros for Lakki and the bay at Xirokambos, then Lipsi and Patmos for the monastery. Turn the other way and Nisyros, Tilos and Symi open up within a comfortable day. Meltemi season funnels breeze down between the islands, and a catamaran that sits flat and draws little takes the anchorages the monohulls have to give up.
The eating is the point as much as the sailing. Vathy on Kalymnos, Pandeli on Leros and Pedi on Symi keep tables at the water where the only sensible approach is by tender, and the local goat, the capers and the thyme honey are worth planning a day around. Aquinox books the berths and the tables before you arrive.

The saloon of this Excess 12 charter Kos runs the full beam under panoramic glass, with an L-shaped settee and a dining table to port and a straight bench to starboard. The galley sits along the port side with a three-burner hob, an oven, a deep sink and a full-height fridge-freezer, so whoever is cooking is still in the conversation rather than exiled below. Pale oak joinery and a light sole keep the interior calm rather than glossy.

A chart table with instruments, breaker panel and VHF sits forward to starboard. The cockpit is on the same level as the saloon with a second table and a long bench, and the coachroof overhang shades it through the hottest part of the afternoon without a single zip or clip to undo.

Each hull of this Excess 12 charter Kos carries two double cabins, and each has its own head with a washbasin and shower rather than a shared wet-room. Hull windows at berth level mean you wake to water instead of a porthole, and opening hatches above every berth matter more in the Aegean than any amount of joinery. Two further single berths in the bow compartments take the boat to twelve if you need them. Linen and towels are laid out fresh on turnaround.

Twin trampolines forward make the best seat on an Excess 12 charter Kos under way and the best place to eat breakfast at anchor. Aft there are bathing steps on each hull, a dinghy with an outboard on davits, and cockpit speakers wired to the saloon. Snorkelling equipment comes as standard, and a paddleboard or a second outboard can be added to the booking.
Rates for this Excess 12 charter Kos open at €3,100 per week out of season and run to €8,950 in the first weeks of August, with a standard charter pack of €250 covering transit log, cleaning, linen and towels. A skipper can be added by the day. From the same waters see the Lagoon 43 in Kos, and for a newer four-cabin platform out of Rhodes the Bali 4.1. The full Aquinox fleet is listed by base and cabin count, and the yard publishes the model specification at Excess Catamarans.
