Ouch!!! 18,000 Euros is $23,853.60! Now buy a mainsail and battens for $1500, add tax and you are close to $27,000! Oh, I forgot to ship it to the US, so add that on! I am beginning to think that the A2 price might look pretty good, but I am comparing to a M18, not the Marstom A Class.
There should be some savings for deleting spinnaker gear, but probably not enough to make the Marstrom a price advantage over a brand new, sails included, NACRA A2!
