Hei,

Avoid buying a used dutch North Sea Boat. They sail mostly hardcore there and the environment conditions are doing (giving the boat) the rest ;-) Here is a popular site for used catamarans in GER if you are interested:

If you find a South German one the chance is high that you get a nice boat that has never seen salty water and waves.

Take in account that the boat width of 2,59m is too much for many European road laws. If you pick the Katamaran somewhere in EU-Europe you propably have to trailer it sloped or in parts.

I would go for the Infusion btw.

Good Luck for your search. If you need translation for german ads feel free to contact me.
