Both marine and non-marine training providers offer training courses for stewarding and catering skills such as:
• Silver service
• Wine appreciation
• Table management
• Bar management
• Floristry
Courses also exist covering an overview of all of these types of skills, sometimes including certifications such as STCW Basic Safety Training or RYA qualifications.
Once again, you should include on your CV full details of what you have achieved and an outline of what skills you have learnt (for example a brief syllabus). This will help potential employers to know exactly what training you have received, even if they are not personally familiar with the course.
