Pantaenious refused to renew my insurance
in 2019 stating that they no longer insure either Canadian or US flagged boats in the Med ( ours is Canadian flagged).
I now have local third party liability ( compulsory ) Spanish insurance at the annual cost of about 63 Euros. For all practical purposes, basically self insured. The boat
is a 1983 Shannon 28, and neither Pantaenious nor my current
Spanish insurer would provide hull
coverage on the basis that the boat is too old.
If, like me, you are comfortable with only third party liability, compulsory coverage in the Med is quite inexpensive.
