CM 46 Buyer's Guide
The CM46 is a 46-foot semi-custom catamaran from Current Marine, designed with Schionning Designs and built in low-volume production since 2021. For a shopper on the brokerage market, it presents as a lightweight, performance-oriented cruiser with unusual structural seriousness and a high degree of layout flexibility rather than a volume-built charter derivative.
Layouts on the Used Market
Hulls widen above the waterline to give queen size berths and ample stowage, and the starboard owner's hull typically carries a large forward bathroom with wet locker and washing machine space. The port forward cabin is convertible between double, twin bunk, or workshop modes. Builders offered three- or four-cabin arrangements, and owners have reported plenty of opportunity for layout customisation in those configurations. Sliding cockpit doors open 1.8 metres wide into a 5.4-metre single-level saloon, with panoramic sightlines from both saloon and cockpit. A large galley with strong worktop and stowage space and a forward facing chart table round out the central living space.
Equipment and Common Upgrades
Power and energy choices centred on twin 30hp shaft drive diesels or an electric/diesel hybrid, with 2 x 40 gallon fuel and 2 x 53 gallon water tanks. Rig upgrades are consequential: aluminium or carbon spars in 17.5 or 19 metre lengths, with Y-section carbon booms, and an optional UpSideUp anti-capsize sheet release system. Helm configuration matters for offshore use — twin wheels, tillers, or versa helms that hinge from exposed to protected positions. Canvas and sail handling benefit from lines led to winches at the wheels for single-handed work and inward angled carbon daggerboards that raise to ease autopilot load downwind.
What to Inspect
The structural brief is the boat's strongest suit and the area to verify on any candidate. The construction employs post-cured infused epoxy with a closed-cell foam PVC core epoxy resin, infused and post cured, which will not take up water if damaged locally, while carbon adds standard reinforcement. Confirm the crash bulkheads in the bow sections and forward of the rudders remain sealed watertight compartments, since they are the boat's flooding containment. Check that the longeron and forward beam are sound where laminated into the hull, and that foam cored furniture remains laminated in without creaking. Bow area laminates carry extra strengthening for collision resistance — inspect for prior impact.
Availability and Buyer's Takeaway
For a buyer, the checklist is straightforward:
- Verify epoxy/PVC core condition and absence of water ingress at any laminate damage
- Confirm watertight crash bulkheads and sealed forward rudder compartments intact
- Match layout (3 vs 4 cabins, convertible port cabin) to intended liveaboard use
- Assess rig choice (aluminium vs carbon, mast length) against sailing plans
- Confirm propulsion type (diesel vs hybrid) and tankage for range needs
