There is no charter base on shore that changes the engine oil for you or repairs the toilet. We have to do all of this ourselves or pay someone to do it. On the other hand you get a boat that has withstood 37 years with a totally sound hull and now a completely new deck in teak which creates a very high life expectancy. The boat is quite fast compared to todays plastic charter boats. It is also much more reliable and seaworthy than a chartered boat.
Potential owners have to have the necesary licenses.
Beyond that they should have skippered an offshore yacht of similar size before. The boat has been run on a shared basis for ten years now, so we have found out how we get on with each other well.
