Diam 24 Buyer's Guide
Shopping the used Diam 24 one design means looking at a 24-foot trimaran conceived as a multihull sportboat and refined by VPLP for one-design racing, not a cruiser with berths and galley. Built as a demountable platform with a rotating carbon rig, the boat was designed from the start to disassemble for transport, so a used example lives or dies by how cleanly its previous owner managed that break-down-and-trailer routine. Spanish coastal listings are the typical market you will encounter.
Layouts on the Used Market
Every Diam 24 follows the same one-design hull: a 23-foot-9-inch trimaran with an 18-foot-6-inch beam and a large cockpit built for three or four people day sailing or buoy racing. There is no cruising interior to compare — the layout is an open, inviting cockpit with stowage for all components in the forward compartment and cockpit when broken down. A used buyer should expect the seaside-rated platform to show as a racing-dayboat shell rather than a weekender, with the central hull clear of the water under sail thanks to twin rudders on each floater and a single central daggerboard.
Equipment and Common Upgrades
The standard package on these boats commonly includes a code zero and a gennaker as part of the light-air inventory, which matters because the minimized sail plan is built around main, jib, and gennaker in black aramid and laminate film. A three-horsepower electric Torqeedo comes in the standard auxiliary role, useful for nudging off a beach or into a mooring. Beyond those, the most consequential buyer items are the launching dolly for ramp or beach launch and the D Box framed container that keeps the disassembled boat's parts together on a trailer or truck — both speak directly to whether the seller actually used the boat as designed.
What to Inspect
Because the structure is a demountable glass-and-carbon sandwich, the coupling points deserve close attention: the manufacturer cites a highly effective cones-and-sockets mechanism that keeps assembly ultra simple, and the floats attach to the hull with straightforward toggles, so worn or cracked sockets and toggles are the first place a rushed breakdown leaves its mark. The beams are non-folding by design to guarantee rigidity across the beam, so check the beam-to-hull joints for stress marks after years of one-design racing. Resin-infused hulls and floaters use PVC foam core with carbon UD reinforcements, and the foils follow the same epoxy recipe, so any gelcoat breach near a foil root or beam fairing is worth a surveyor's look rather than a polish.
Availability and Buyer's Takeaway
The Diam 24 one design turns up in Spain as the typical market, and a buyer there should treat the boat as a racing-day sailer that must assemble in an hour with two people to be worth owning. Look for clean cones-and-sockets coupling, intact float toggles, and a complete D Box and dolly set before negotiating.
- Confirm cones-and-sockets and float toggles are uncracked
- Verify beams show no joint stress from non-folding rig
- Check gelcoat at foil roots and beam fairings
- Ensure D Box and launching dolly are present
- Confirm code zero and gennaker are in the sail inventory
