Shoes, its a big no-no to wear your land shoes on the deck whatever they are, but especially heels. All land shoes should be taken off before you get on the gangway and will be put in a shoe box while sailing. Most yachts will not allow any shoes that have been worn on land to be worn on board unless they are thoroughly cleaned first, so it’s a good call to have a dedicated pair of shoes to wear just aboard, else go barefoot.
Suncream damages the teak and makes the deck slippery and potentially dangerous. For this reason, please be careful when applying it and don't use sprays when it is windy as it is likely to cover the boat, those downwind of you and probably not very much of you! If you are sunbathing on the teak deck, please lie on a towel.
Smoking is not usually encouraged on board, although if you have to, please ask the captain for his rules. It is usually ok to do it on deck only and when you do smoke, please choose a spot downwind so that the ash and smoke blow away from the yacht and others.
Crew, the crew are there to make sure the yacht is safe and to ensure your stay is as comfortable and luxurious as you dreamt of. Don't be afraid to ask for a drink or snack at any time, or if you have any other requests just let them know. It’s really helpful to discuss your requirements for the day with the captain at breakfast time, he can then advise on suitable anchorages for lunch and the evening. It’s a good idea to tell him at this point if you want to have meals aboard or ashore, so that they have time to prepare. The crew are experienced at working out how much or little interaction you want with them, but don't be afraid to ask if you want some privacy or if you want to share a drink with them and hear some stories. The majority of crews will not eat with you, they don't mind as they will be busy preparing your meal, drinks, etc. However, if you would like them to join you for dinner then feel free to just ask. Likewise if you are eating out, they will assume that you will do this as a family/group and they will probably enjoy the peace for a few hours. But again, if you would like them to join you, please do ask. If you want to stay out and party then you should make a plan with the captain for getting you back aboard. He’ll be available to collect you in the tender at any time of night but you will need to warn him of what you plan to do. If you are on the dock and expect a late one, please let the crew know if they can go to bed before you return or take them with you.
