What KateBot thinksStrengths and trade-offs
Perfect for groups This 2020 catamaran is ideal if you're chartering with friends or family, 12 berths across 6 cabins means you'll split costs nicely and have genuine privacy. The twin-hull design also gives you excellent stability and space, which larger groups really appreciate after a long flight out.
Well-equipped modern boat You're getting a genuinely practical package here: solar panels, electric toilet, inverter, and autopilot all reduce hassle on the water, while the lazy jack and bimini make life comfortable. The inclusion of snorkeling gear and cockpit speakers suggests an operator thinking about the full experience, not just bare essentials.
Strong value proposition At €5,220 per week with zero deposit required and backed by Istion's solid 5-star rating (12 reviews), this represents fair pricing for a modern, well-maintained six-cabin cat. Split among 8, 10 people, you're looking at under €600 per person weekly, genuinely competitive.
One practical note The base location isn't specified in your details, so confirm airport transfer time and whether Istion arranges this, that matters when you're coordinating multiple flights into Greece. Otherwise, this is a straightforward, low-fuss choice for a larger group charter.
