The Stejcraft 640 Monaco is a 6.47 metre trailerable cruiser from Stejcraft, a boat builder in Arundel, Queensland. Stejcraft's own homepage calls itself "premium boat builders since 1971" with "over 50 years of boat building experience," and the 640 Monaco is one of the family cruisers in its Monaco line, alongside the smaller 610 and 580. It is built around an overnight cabin and a day boat in one trailerable package, not around a dedicated offshore fishing setup.
A 2004 example and a 2006 example both turn up in Boattrader's listing history under the 640 Monaco name, which puts at least two decades behind the nameplate, if not the current DLX hull specifically. Stejcraft's own site doesn't give an exact start date for the model, only the company's 1971 founding, so treat "at least two decades" as the floor, not the full history.

Stejcraft builds the hull from what it calls "11 layers of fibreglass," with a "wood-free construction and composite-moulded stringer liner," so there's no timber stringer to rot the way older hulls can. That doesn't rule out other age-related issues like delamination or water getting into the core, it just rules out that specific one. Standard kit on the DLX runs to a lockable cabin, a freshwater tank, a toilet, a shower and a fully flat cockpit floor, per Stejcraft's own spec page. There's no price for the current model on that page.
For how it actually performs, you're stuck relying on older reviews, and the figures show their age. Boatsales tested a 2023 model with a 200 hp Mercury Verado and clocked just under 40 knots flat out, a cruise around 25 knots, and a theoretical range of 186 nautical miles at 3,500 rpm. An older TrailerBoat magazine test by Bernard Clancy ran a 200 hp Evinrude FICHT two-stroke (a motor nobody sells any more, Evinrude closed its outboard business in 2020) and got around 100 km/h at wide open throttle. Both reviews call it a cruiser first. Boatsales put it plainly, "definitely set up as a cruiser first, and a fishing boat second," while also noting the deep-vee hull (27 degrees at the bow, 21 degrees at the transom) "cuts through wake and chop comfortably at any speed" and that the boat is "more than entirely capable of heading offshore for a day of fishing." It also noted the walk-through transom door sits on the starboard side only, so think about how you'll load passengers before you back down the ramp.
What people ask for one now
Three Stejcraft 640 Monacos are listed for sale on Boattrader as of 1 October 2026:
- 2006 Stejcraft 640 Monaco Sports Cruiser, asking $3,990. The seller says they bought the hull to detail and resell, need a quick sale, and the hull and trailer are both registered, but the trailer's rated capacity is flagged as something a buyer needs to check for themselves.
- 2025 Stejcraft 640 Monaco Cruiser, asking $133,000, from a WA dealer, fitted with a 175 hp Suzuki four-stroke, Garmin electronics and a full camper cover set.
- 2026 Stejcraft 640 Monaco Cruiser, asking $126,288, the same WA dealer's base-model DLX.
Don't average those three, they're not comparable. A 20-year-old hull being sold as a cheap restoration project and two brand-new dealer boats share a model name and not much else. Condition and age matter more here than any single price figure. As context, Boatsales' 2023 test boat was priced from $97,000 with a 150 hp Yamaha and $115,000 as tested with the 200 hp Mercury, and a much older TrailerBoat test of an earlier Monaco listed $48,900 to $55,200. New dealer stock has moved well past both of those since.
What to check on a used one
Some of this comes straight from the two reviews above and Stejcraft's own published specs. Some of it is ordinary used-boat buying sense that applies here as much as anywhere, and we've kept the two separate:
- The trailer rating, not just the boat. The 2006 listing above spells this out itself: the private seller flags that the trailer's tare and aggregate mass need checking against what you actually plan to load. On any used trailer, check the compliance plate against the combination you're buying and confirm the VIN and registration match, since a trailer can be swapped or re-registered separately from the hull over 20 years.
- Fuel capacity against how you'll actually use it. TrailerBoat's review of an earlier carburetted two-stroke Monaco called the 200 L tank "a bit light-on for a full day's skiing." A modern four-stroke generally burns less than an older two-stroke, but the tank hasn't grown, so do the sums for your own trip length rather than assuming a full day is covered.
- Loading and the transom door. Boatsales noted the walk-through door sits on the starboard side only. That's a layout choice, not a fault, but better to know it before you buy than work it out at the ramp.
- Hull and outboard condition, the ordinary way. Neither review covers this and it isn't specific to Stejcraft: on any hull this age, check for stress cracking, past impact repair and signs of water getting into the core, and ask for the outboard's service history and hours. A sea trial and, on an older hull, an independent marine survey are worth the cost before you commit.
- Cabin fit-out wear. The freshwater tank, chemical toilet and cabin upholstery are the parts of a trailerable cruiser that show their age fastest. Ask when they were last serviced or replaced on anything more than a few years old.
Who it suits
This is a boat for towing to the water, cruising the day away, doing some casual fishing along the way, and sleeping aboard if the trip stretches into a weekend. The cabin, toilet and shower on the boatsales test boat were there for that overnight use, and the modular transom seating on newer models converts between a lounge, a dinette or an open cockpit rather than being built around a fighting chair.
It isn't marketed or set up as a dedicated fishing boat first, both reviews agree on that. But it isn't out of its depth offshore either: Boatsales called its deep-vee hull "more than entirely capable of heading offshore for a day of fishing." If you want a boat built primarily around serious offshore fishing, there are better-suited hulls for that job. If you want a family cruiser that can still put in a decent day's fishing on the way, this is closer to what you're after.
