Moody 31 Mk I Buyer's Guide
Shopping the brokerage market for a Moody 31 Mk I means looking at a defined group of 259 fiberglass hulls built by A. H. Moody & Sons in Southampton between 1983 and 1987. Bill Dixon's 30-foot 9-inch cruiser has a practical three-cabin interior and a masthead sloop rig, and used examples turn up across several European markets.
Layouts on the Used Market
Owner three-cabin layouts are the more common on the used market, but both are available; ex-charter examples are common. The standard arrangement sleeps six with a forward V-berth, saloon settees, and an aft cabin, plus a galley and enclosed head. Ex-charter history is worth noting because fleet use can mean harder wear on saloon cushions, galley fixtures, and deck hardware than a privately maintained boat.
Equipment and Common Upgrades
Autopilot, heating, spinnaker, and chartplotter are commonly fitted, so most boats will already steer and navigate without immediate expense. Solar panels, dodgers, and life rafts are often seen, covering basic power and safety. A buyer should check that the heating system is serviced and that the spinnaker included matches the 595-square-foot asymmetrical or 736-square-foot conventional sizes the rig accepts. Less common but possible upgrades include electric winches, hot water, a swim platform, AIS, an inverter, an asymmetric spinnaker, a bimini, and radar — these tend to mark an owner who cruised the boat seriously.
What to Inspect
At a viewing, tap the solid fiberglass hull and deck for hidden repairs and check the skeg-hung rudder bearing for play. The Volvo Penta MD2003 diesel on shaft drive should be started cold to confirm clean running and no shaft-seal weep. Verify the masthead rigging terminals and chainplate bedding for corrosion or staining, and confirm the teak joinery is not soft or delaminated from cabin leaks.
Availability and Buyer's Takeaway
These boats are typically found in the United Kingdom, France, and Norway. Before committing, run through a short checklist:
- Confirm hull and deck soundings are clean
- Check rudder bearing for free play
- Start the Volvo Penta cold and watch the shaft seal
- Inspect chainplate bedding for stains
- Test the heating and autopilot if fitted
- Verify spinnaker size against the rig
