Yes, at least $200K in improvements - probably more. My boat has A$250K in improvements for instance. The base boat price
you quote requires considerable upgrades to bring to cruising spec.
As an example boat supplied in the last month out of La Rochelle was A$850k. This was pretty specced up but not to that degree of 1GL. It was sailed out of La Rochelle, but if shipped to Australia
this boat would run $1.1 million.
This is not to say that 1GL is priced correctly. I suspect it will sell somewhat under the asking price. However, it is always difficult to compare prices of different boats due to geographic location and specification, and then you have to form a view on applicable depreciation.
