2016 Cutwater C-24

Engines

220 hp Volvo Penta Diesel:

• Model: Volvo Penta D3-220 (inline 5-cylinder, 2.4L turbo-diesel with common-rail injection)
• Rated Power: 220 hp (162 kW) at 4,000 rpm (crankshaft); ~209–213 hp at propeller shaft
• Drive: Volvo Penta DPS Aquamatic DuoProp sterndrive
• Torque: Peak around 464 Nm at 2,500 rpm
• Fuel Type: Diesel
• Notable Traits: Aluminum block for lighter weight, strong low-end torque for planing, electronic controls, NMEA 2000 integration. Marketed as sipping fuel for longer excursions compared with the gasoline option.

Comparable Volvo D3-220 installations in similar-sized boats typically cruise efficiently in the mid-teens to low-20s knots range, with the diesel praised for economy at displacement and mid-cruise speeds. Owners of related Cutwater/Ranger Tug models with the D3-220 often report comfortable cruising around 14–18 mph with good fuel burn.

Engine RPM context (Volvo Penta D3-220):

• Rated WOT: 4,000 rpm (Volvo also lists a brief maximum around 4,130 rpm).
• Typical guidance for this engine on Fluid Motion boats: keep extended cruise at or below about 3,600 rpm(roughly 90% of rated WOT). Short bursts higher are acceptable.

Exact RPM-vs-speed tables for the C-24 hull + D3-220 were not published the way Yamaha later published outboard performance bulletins. Closest real-world owner data is from similar stepped-hull Cutwaters with the same D3-220 (mostly C-26s, which are heavier):

• RPM (approx.)
• Speed on C-26 D3-220

Notes:

• ~2,200–2,250
• ~7 knots

Displacement / low-speed cruise:

• ~3,220–3,380
• ~10.5–14 mph

Common economical cruise:

• ~3,500–3,600
• ~13.5–18 mph

Faster cruise; often cited as practical max continuous:

• ~4,000–4,120
• ~20–23 mph

WOT on the heavier C-26.

The lighter C-24 (about 5,300 lbs dry vs. a heavier C-26) should be faster at the same rpm, which is consistent with the published 26 mph cruise / 40.4 mph top for the diesel I/O C-24.

Practical takeaway for the 220 hp diesel C-24

• Comfortable / efficient cruise: mid-teens to low-20s mph, typically in the 3,300–3,600 rpm band.
• Published cruise number: 26 mph.
• Top speed: about 40 mph (40.4 mph published).
• Fuel burn on related D3-220 installations is often in the 8–10 gph range at those mid-cruise rpm settings, but load, bottom condition, prop, and sea state change the numbers a lot.

Yamaha 9.9 kicker for trolling and back up needs.

Hull Design

Performance Features:

• 24° deep-V forward for a smooth ride
• 11° keel pad for planing stability
• Reversed chines for quick planing and reduced cornering roll
• Double-stepped hull for efficiency, reduced fuel use, and faster time-to-plane
• Patented Laminar Flow Interrupters (LFI) for positive, stable cornering
• Electric trim tabs

The design aims for a quiet, soft ride and good handling in a compact package.

Accommodations

Layout:

Typical 2016 Coupe/Cruiser layout sleeps 4:

• Private forward stateroom with wrap-around seating and high/low table that converts to an oversized double berth
• Mid-cabin/salon dinette that seats 4 and converts to a berth
• Enclosed head with marine toilet, sink, and shower area
• Galley with refrigerator, microwave, stove/cooktop, and sink
• Opening aft bulkhead with reversible seat that faces the cockpit
• Good headroom (around 6’2″–6’6″ in cabin areas)

Three dining/social areas are often noted: forward, mid-cabin, and cockpit.

Features and Equipment

Standard/common on 2016 models:

• Garmin navigation package (chartplotter/GPS/sonar)
• VHF radio
• Fusion stereo system
• LED lighting (including indirect cabin lighting)
• Marine head with holding tank and pump-out
• Bow pulpit and swim platform with boarding ladder
• Windlass (bow and helm controls on many boats)
• Bow thruster
• Rod holders and sport racks
• Cockpit sink and drink holders
• Opening portlights and hatches
• Self-bailing cockpit
• Anchor package (chain + line)
• Inverter
• Macerator discharge
• Underwater lights
• Air conditioning / reverse-cycle heat or diesel heater
• Radar
• Trailer (tandem-axle)
• Yamaha 9.9 hp kicker on some boats
• Engine heat exchanger use for cabin heat

Cutwater loaded these boats with more factory-standard items than many similarly sized cruisers of the era.
