The Hobie Mirage Adventure Daggerboard will give you extra control while sailing. The daggerboard slides into the slot to the right of the Mirage Drive. The 24 in. long fin acts like a skeg to provide better tracking and control while sailing. The daggerboard does not interfere with the Mirage Drive fins and can be kept in place while pedaling.
This Dagger board performs really well. It gives the Adventure Fish and added level of stability when sailing. I especially like the way it folds under when in shallow water. I found it to be well designed and functions as promised if not better. I will not sail my yak without it!
