liability insurance wooden 80 ton sailingvessel

[Mark10]

Hi All,

I am not sure if this is the place to be, sorry if not so.

I am looking for a liability insurance for my 1957 wooden Danish trawler converted to motor/sailing vessel from 80 tons. The ship is is in very good condition.
We go in august for a long voyage from the Netherlands to the Caribbean and more.
We like to have a liability insurance. We are at the moment located in the Netherlands, but insurance can be taken from anywhere.
At the moment we have an insurance till Portugal from a Dutch classic boat insurance company.
All tips and info is more than welcome.
If you are, or know, someone who made longer voyages with a traditional wooden vessel with insurance, then I would like to get in contact.

Thank you very much.

Regards,

Marco
