What the fleet has seen

The Maestro Boats 31, as the fleet has seen it

Derived from the videos the fleet has analysed of this model. ▶ marks open the moment aboard.

The Maestro Boats 31 is a 9.3-meter fractional sloop designed by E. G. Van de Stadt as an IOR 1/2 ton racer, built from 1982 to the present. It has a fin keel with a spade rudder, a 3.1-meter beam, 1.7-meter draft, and displaces 2500 kg. The model is among the vintage racing yachts sought for restoration to revive the Half Tonner racing class in Norway, aiming to recreate the competitive environment of the 1983 Half Ton World Championship.2:33 This initiative involves sourcing neglected hulls and establishing a local racing circuit using IRC handicapping.7:56 Restoration efforts for boats like the Maestro 31 include deck hardware replacement, engine overhauls, and sail upgrades.5:31 Owners prioritize rig integrity, monitoring mast condition and managing running backstays, which are critical for supporting the tall, thin rigs characteristic of the era.3:09
