Parts Compatibility

Maas Boats has strived for consistency over the years, but inevitably some parts suppliers come and go, or designs change. This is a partial list to help make sure the replacement parts you purchase will work with your shell. If in doubt, please feel free to contact us for help.

Wing Riggers

Wing riggers are not interchangeable across our shells. The Winged Aero and the Maas 24 share the same basic wing, but there are some differences in the angles. Likewise the Flyweight and Maas 27 share a rigger, but with differences in the angles. The Maas Double has it’s own wing. The Classic Aero can only take a wing with the adapter kit, the internal structure of the Classic is NOT designed for the stress of the wing without reinforcement.


The Pocock seat (black carbon top) works with all track in our shells. The Maas seat (white top) is NOT compatible with the Pocock track that has been used in new builds starting in 2020.

Note there was a brief period in 2019-2020 where Martinoli parts were used in the double-action seats. These parts are metric and cannot be swapped with the US equivalent. If in doubt, send us a photo of your seat's undercarriage when ordering seat parts.

Seat Track

The new Pocock track used starting in 2020 will ONLY work with the Pocock seats (black, single-action). The clip on the undercarriage of the Maas seat (white) is too snug on the Pocock track and the seat will not slide.

Footstretcher Channel

Starting in 2020 Pocock footstretcher channel has been used in our boats. It is notched, including the center channel. Two things to take note: with the notched center channel a washer is used between the channel and the footstretcher. In all cases the spacer is above the footstretcher to provide access to the wing nut.

Note: the Pocock footstretcher channel is slightly taller than the old channel, but is otherwise a direct replacement.

Critical: if the center channel is notched, use the supplied washer between the channel and footstretcher.

DO NOT place the center bolt spacer – plastic or phenolic – below the footstretcher to change the angle, you will damage or break the footstretcher.

In NO CASE should there be any other item or material between the stretcher channel and the footstretcher, you will damage or break the footstretcher.
