GRAYONE Yacht Description
-
Jet Ski (Sea-Doo Spark):
Rare on a catamaran, perfect for quick island runs and high-energy water time. -
2 Hydrofoil boards (flight scooter):
One of the most popular toys right now, great for flying above the water. -
Starlink Satellite Internet:
Reliable connection for calls and remote work, even when anchored in quiet bays.
Big cat, big decks. GRAYONE is a Sunreef sailing catamaran built in 2020, around 80 feet long, with the kind of deck space that stops groups from living on top of each other. Dark grey hull. Three teak decks. You get the idea.
Easy water access. The hydraulic swim platform is the practical hero here: simpler swims, simpler launches, and a cleaner on-and-off routine for the 16ft Castoldi Jet Tender (110hp). No gymnastics. Just water time.
Toys for busy days. Bring a competitive streak: a SeaDoo stand-up jet ski, Seabobs, hydrofoil boards, wakeboard, water skis for adults and children, paddleboards, snorkelling equipment, plus inflatables including a floating island and mats.
Eight guests, four cabins. GRAYONE sleeps 8 in 4 en-suite cabins: 1 master, 2 doubles, and 1 twin, with TVs in all cabins. Air conditioning and Wi‑Fi (including Starlink) keep things civil when you are done playing outside.

Price Terms
Plus Expenses - add APA to the price you see
Plus Expenses arrangement includes the boat and crew only (without tip).
All additional/variable expenses such as Gas and Food are deducted from an Advance Provisioning Allowance (APA) - an additional deposit that is added on top of the charter price.
The expenses, such as provisioning, fuel, marina fees, are deducted from the APA. The APA is based on the price of the yacht and ranges from 15% (crewed sailing yachts) to 30% (motor yachts with higher fuel consumption).
For a sailing catamaran like GRAYONE, the expected APA is 20% to 35% of the charter price (€11,200 - €19,600), making the charter cost €67,200 to €75,600. Exact amount will be confirmed after inquiry.
You can actively control these expenses in your preference sheet (local vs. imported beverages) and by choice of itinerary (distances traveled).
The remainder of the APA is returned after charter.
