Down in the guest harbor in Karlskrona city marina, the sailor Sverker Ullerstam has added. He comes from Gothenburg and is an experienced sailor for several years.

"This with corona you ignore, because there is nothing safer than a lonely man in a sailboat on the sea," he says.

He takes up the book "Maritime regulations etc." which he has lying inside the cabin on his sailboat. Not all boaters follow the rules, he says.

- In the middle of summer in Bohuslän you can not be there. There are too many boats, too much ignorance and recklessness.

"Not easy to navigate"

Mikael Svensson and Ann Berggren live in Viken and have both grown up with boats. They are about to leave Karlskrona to sail down towards Hasslö.

They understand why more people buy a boat now, when you dare not travel and may not want to buy a summer cottage. But there are a lot of things to think about before embarking on your new boat.

- It's not easy to navigate, it's a thing you have to learn. It is not only possible to test, but you must have basic knowledge there, says Ann Berggren.
