Disappointment on every level! Just half an hour after booking on the portal, the owner called and stated his conditions: no suitcases on board (not even for repacking), no fishing, no shoes with black soles. Later, he also objected to a clothesline we had hung overnight on the gearshift lever. The lever could break, he claimed. Copies of ID cards were immediately demanded from all (!) crew members. Furthermore, the owner pressured us into a so-called skipper training course for €60. Two days before it was due to start, he informed us that the boat wasn't ready. We agreed to postpone it by a week. There was no discount for our cooperation. The skipper training turned out to be more of a practical driving test. With over 50 years of boating experience and at least as many trips, as well as holding a boat license, the whole thing wasn't exactly new to me. But after a year's break since my last boating holiday and an unfamiliar boat in a strange harbor area, things didn't go perfectly from the start. The instructor intervened a few times. In his opinion, he had to do that to avoid a collision. How about a little warning beforehand? That would have been more in line with what I would consider skipper training. As it was, I was declared unfit to operate the boat. We were denied the option, provided for in the terms and conditions, to attempt another sailing session the following day. The rental company did not respond to my subsequent notification of this violation. A refund of the boat rental fee was refused. We had to spend the week in the harbor. That wasn't what we had in mind. Based on this experience, I can't imagine going on another boating holiday at the moment.
