I'm looking for daggerboards for my 5.2 and noticed that the daggerboard for hobie 20's look very similar. Does anyone know if they are interchangable? ~Reid

They are not. Murray's has 5.2 daggerboards. Nacra 5.8 and 5.5 are the same as my 5.2 boards.

According to the Nacra parts manual, the 5.2, 5.5, and Nacra 18SQ use the same board. The 5.8 and 6.0 share a different board. I would be extremely surprised if a H20 board fit.

Has anyone else noticed that a Hobie 20 looks like a Prindle 19 with NACRA 6.0 daggerboards?
