The MC55 might be the smallest multihull in the McConaghy range, but this cat is no kitten.
Designed to be sailed and cruised by couples and families alike, the MC55 offers a hugely safe, spacious and comfortable platform that is incredibly easy to handle thanks to her clever layout and the technology installed.
The MC55 not only benefits from McConaghy’s vast experience building performance boats, but also from the carefully considered use of carbon, that sees her precise hull forms achieve an optimum strength to weight ratio. As with all McConaghy MC Multihulls, the MC55 has dual helm positions on the flybridge, allowing for the greatest sight lines forward, as well as an elevated position that aids in-port manoeuvres – making her an ideal choice for those new to multihull cruising.
With several MC50s sailing, this boat really should be a top consideration if performance cruising is on your goal..
