A real Colin Archer is of course a boat designed and built by Colin Archer or designed by him and built to his designs without too much modification.
Today Colin Archer is used as term to describe all kind of sailing vessels that have similarity to the Norwegian "Skøyte", even though they have nothing to do with Colin Archer.
In other countries they do not have a name for "Skøyte", so even Swedish and Danish boats of similar design is referred to as Colin Archer.
Even boats built in steel and plastic, with little or no resemblance to CA designs are referred to as Colin Archer's.
This is done to describe the type of boat, ie pointed aft. Often it seems to be an attempt to achieve better price when selling or for better status.
Anyway, perhaps this has made Colin Archer's name and the southern "Skøyte" the most famous type of boat in the world.
Colin Archer started his career by copying the "Hvaler Skøyte", and looked at other "Skøyte" designs in the districts around. Places where "Skøyte" construction had taken place before he started, this includes Tenvik (by Ula), Risør and The southern coats in general.
Many builders looked on course Archers boats and made their improved versions that could be just as good and maybe better than several of Colin Archers designs.
There are some famous boats that Colin Archer undeserved is credited for here are two examples:
"HoHo" built in 1908, probably by the legendary boat builder Nils Eriksen Narvik in Risør as the pilot boat "Fast" probably designed by Jens Brandi, a famous Boat designer from Risoer.
"Rundø" was built and designed by Christensen & Moen Risoer in 1925 as a pilot boat.
Both these boats sailed around the world in respectively 1933 (HoHo) and 1958 (Rundø), there are books written about these voyages.
