Nelson Marek 46 Buyer's Guide
Shopping the brokerage market for a used Nelson Marek 46 means understanding that this Carroll Marine IMS racer is a 1995-onward design with only six units produced, and that the boats afloat today are almost entirely rule-driven racers with minimal interiors. Both owner three-cabin layouts and ex-charter examples are available, with the three-cabin owner versions more common on the used market. What you are really buying is a 46-foot-7-inch, 18,500-pound thoroughbred with 11,000 pounds of lead on a 9-foot-2-inch fin — not a comfortable cruise-and-charter platform.
Layouts on the Used Market
The more common used boats are owner three-cabin arrangements, but both layout types turn up. Ex-charter examples are common as well, and a charter history should be read as harder cyclical use rather than a defect in itself. Either way the interior is minimal, with weights centered for IMS compliance and only 40 gallons of water and 20 gallons of fuel — so layout choice is less about luxury than about how many sea berths you need for a crew-oriented boat.
Equipment and Common Upgrades
On the used market, autopilot, asymmetric spinnaker, and AIS are commonly fitted, which tells you these boats are often sailed short-handed or race-prepared with modern navigation. Often-seen gear includes a code zero, spinnaker, hot water, bimini, dodger, and chartplotter — a cluster that splits into sail-handling upgrades (code zero and spinnaker for reaching and running power) and basic cruising comfort (hot water, canvas, plotter). The Volvo 50-horsepower diesel with its integrated saildrive unit is the factory installation; its drag-minimizing placement in the keel wash is a point in its favor, but confirm the seal condition on any example. Steering through Edson's Spectra line-and-spool system is original-spec light-weight gear worth checking for spool wear.
What to Inspect
The saildrive installation should be surveyed for seal and gear integrity, since it integrates shaft and strut into one assembly saildrive unit on the Volvo diesel. The solid fiberglass hull and deck and Kevlar construction are sound background. A survey should still confirm the four-spreader rig's runners, checkstays, and short jumpers at the hounds for tuning hardware fatigue, as these are load-bearing on an IMS rig.
Availability and Buyer's Takeaway
These boats typically appear in the United States, Croatia, and Spain. For a buyer, the takeaway is simple:
- Prefer a documented owner three-cabin layout unless crew charter history is acceptable
- Confirm saildrive seal and gear condition on the Volvo 50-horsepower diesel
- Verify the four-spreader rig hardware and Edson Spectra steering spools
- Treat minimal interior and 20/40 gallon tanks as design fact, not defect
