The 2,4mRclass is an open design class in the same family

as the classic metre yachts as the 12mR, 8mR and the 6mR.


This means that you constantly are trying to get more speed

out of your old pram by progressing in attention to detail

as well as rebuilding the hull shape or refining the keel configuration when you have an idea of how to get another

1/100 of a knot more speed out of your boat.


With good understanding of what produces speed for

a sailing yacht and some work you may very well competetive

at top level in an older yacht. The yellow rocket SWE 162 is a Södergren mk III that was abandoned many years ago. After a thorough update she became a constant threat to the newbuilt yachts.



Some may even be brave enough to build a new better boat

in the garage during winter, or to collaborate with a designer/boatbuilder for a new bid.


This distinguishes it from most one designs, where every

couple of years you have to get a new boat because the old

one is clapped out and no longer fast enough.
