Swimwear and T-shirts is all you will need on board in the daytime.
In the evenings people dress casually, but bring sweaters and trousers if you are coming in the cooler months.
It's a good idea to bring a pair of soft shoes or sandals just to use on the boat.
On board we provide hand and bath towels, so please bring your own beach towels.
All this should be packed into a soft bag which can be folded and stowed away to give more room in your cabin, not a suitcase.
The Mediterranean sun is very bright and on a boat hotter than you think, be sure to pack sunglasses, a good suntan lotion and a hat.
If mosquitoes find you tasty then bring mosquito repellent and a camera is an absolute must.
