RESPONDING TO CUSTOMER DEMAND

Ron Czerniak revisits the modified FatCat 4500

A year ago I tested FatCat’s 4500 Fisherman Open, single console and tiller steer craft (Pacific Power Boat May/June 2022 issue). I concluded that article with the following summary.

“The boats we tested were pretty much FatCat’s entry level spec, but the company offers quite a range of accessories, including twin, single and centre consoles, Bimini tops, seats, grab rails, dive ladders, rocket launchers and a plethora of other options to pimp up the basic boat. Basic or flamboyant, with the FatCat 4500, you get the convenience of a small boat in an affordable package that offers more space than most and with built-in safety and incredibly stability.

With its simple, uncluttered interior design, cleaning up at the end of the day couldn’t be easier. The rugged polymer hull promises to be maintenance-free and comes with a 3 year warranty.

I concluded by asking myself; “Do the FatCat’s achieve their aims”, epitomised by the following words: safer, seaworthy, load, capsizing, self-draining, unsinkable and affordable? The answer was absolutely! And I also added, functional fun”.

Fortuitously I recently attended the Auckland On Water Boat Show and having heard rumours that Blair McLay, the designer and co-founder of FatCat, was working on a cabin version of the 4500. My interest piqued, I searched Blair down on his stand at the Viaduct Harbour, hoping to get a glimpse of this new model. “I found Blair aboard a Double Console FatCat 4500, not surprisingly talking to a very interested potential customer”. But alas, no cabin boat. When Blair was free I asked him if the rumours were true about the cabin version. He confirmed they were and that the boat was for real, but that they hadn’t quite been able get it finished in time for the show. Asking the inevitable ‘when?’ question, Blair said hopefully in a couple of weeks. Next question. “When can we do a boat review and article”? “Soon”, Blair replied.

True to his word, on a brilliant Auckland autumn day at the beginning of April we met up at Gulf Harbour ready to get out on the water and see how this new Cabin 4500 differed from the open Fisherman and to find out if it performed as well, if not better than the two open 4500’s we reported on last year.

Having arrived at the boat ramp shortly before Blair, he soon showed up with a hard to miss, bright green Cabin 4500 in tow. Hmm, no idea why Kermit sprang to mind. This new boat was making a statement even before it hit the water!

As we prepared to launch the boat (not that two people are necessary, such is Blair’s simple and efficient trailer design), I asked him why a Cabin Version? In a nutshell: “We are responding to Kiwi demand for such a craft”. Obviously FatCat had done their market research and had listened to customer feedback. Being a boat designer, it didn’t take Blair long to figure out he already had a great boat in the Open Fisherman, and that all he had to do was design a practical and easy to install cabin for his existing and well proven FatCat 4500 hulls.

The FatCat hulls are rotomolded (rotationally moulded) polyethylene polymer and compared to traditional methods, rotomolded vessels are inexpensive and quick to produce, have a long lifespan, and can take a serious beating. They also happen to be 100% recyclable. A real plus!

By now, Doug had arrived to take pictures of the sea trial and leaving him to head off to the point at the breakwater entrance to Gulf Harbour Marina, Blair and I motored out to put the Cabin 4500 through its paces. 

Chatting on the way out to open water, I more closely scrutinised this new variation to FatCat’s fleet. The first thing that struck me, aside from the obvious huge internal volume of this relatively small craft, was that it adhered to a basic marine principle: KISS (Keep It Simple Stupid). In an ideal world, when you own a small boat, you want a vessel that has all the safety and other features you require for an enjoyable experience, while minimizing things that can go wrong. The Cabin 4500 rates highly on both counts. 

Starting with the helm station, one sees a clean, minimalist configuration; but with all you really need. Wheel and throttle controls for the 60 Hp Honda 4 stroke outboard are positioned exactly where they need to be when sitting, or standing in front of, the comfortable and adjustable, pedestal swivel seat, mirroring the co-pilot’s seat to port. In addition to the Garmin UHD2 75cv chart plotter/depth sounder mounted on the steering console immediately in front of the driver, a GME GX700 VHF radio is conveniently located right alongside to starboard, immediately accessible for routine radio calls or an emergency. The tachometer resides just below the radio and the angle of the console facia permits this gauge, along with the trim meter gauge, to be read at a glance.

But, before exploring the rest of this boat, let us have a look at what makes this a ‘cabin’ boat. Quite simply, Blair ‘plastic’ welded his specifically custom designed, one-piece superstructure; incorporating a fold-back central window for easy access to the anchor locker, onto his existing open 4500 hull. But wait, I hear you cry: “Plastic weld”? Yes, exactly that. Think about how aluminium boat manufacturers weld together their boats and, in essence, it is the same thing for moulded polymer boats. Except in this case there are only two things ‘welded’ together – the hull and the ‘cabin top’. In effect; a bead of hot plastic is run along the two surface parts to be permanently joined together, and in so doing, temporarily melts these two surfaces together and once cooled, the two joined parts and the welds are as strong as if the whole boat had been originally one-piece moulded together. The weld and surrounds become almost invisible after a bit of cosmetic sanding of the surfaces. It’s not Superyacht quality and it is not meant to be. This is an inexpensive family or sport boat – think fishing or diving for example. A boat that you don’t have to worry about if the kids get a bit rambunctious, or dive weights are dropped on the floor or lead fish line sinkers bang against the hull as your catch is reeled on board. It’s a plastic fantastic built for safety and enjoyment. 

With lots of room for up to four people, this catamaran has a beam half as wide as the craft is long (2.05m by 4.6m)! Although somewhat fundamental, the craft, as tested, is sold as ‘ready to go’, including anchor and rode (stowed in a more than adequate anchor locker with an easy access lid and locker drain). Access to the anchor locker is through a ‘fold back’ window, which folds out and back onto the port side of the windscreen and, combined with a lower, fold-down plastic shield, allows you to stand near the bows safely and securely, close to the locker, for easy manual launching or retrieval of the anchor. One of the options FatCat offers is a Maxwell Tasman 6-6 Drum Reel windlass, which easily fits into the existing anchor locker space and is simple to install. 

Positioned in the open windscreen space you find yourself standing in two large, open storage lockers which extend across the full beam of the boat. Wide enough to comfortably stand in, unless you have size 12 feet or larger, these bins provide loads of storage space and aside from stowing things like lifejackets, fishing tackle boxes, scuba tanks, etc.; they are a convenient place to stow all-important chilly bins. I mean, seriously, what’s a fishing trip without a few cold beers when you’re out for a warm summer’s day of fishing? 

On the port side, in front of the passenger pedestal seat and on top of the console, there is a large stow tray, surrounded by retention edges, to prevent items (such as cell phones, sunglasses, etc.) from sliding off when underway. An adequately sized, lidded glove box resides beneath the handy grab rail and to port of this is a fold away drink can holder. Speaking of grab rails, should one be standing at the helm and passenger stations while underway, the top portion of the windscreen sports convenient grab slots, wide enough to hang onto with both hands in a particularly rough sea. I like attention to detail. There is a longitudinal storage locker on the port side forward, beside the passenger seat, but to starboard, this space is logically taken up with the throttle and steering controls and cables, making for a clean and unobstructed look to the whole helm station area.

Looking aft, we once again see the KISS principle at play. Two, 24 litre petrol tote tanks occupy the space beneath the port and starboard stern passenger seats. The battery sits amidships in the built in stern battery box situated between these two tote tanks, which are simply but securely kept into place by a strong length of bungee cord with a securing hook at one end. The fuel filter is located beneath the port, stern seat and the battery switch beneath the starboard stern seat. Speaking of stern seats, FatCat has cleverly fitted detachable, swivel seats. Want to get them out of the way while fishing or diving? Press the Release mechanism and lift and stow them up forward in those large bins. But when

in use, these two stern seats are arguably the most comfortable place to sit on this boat; especially while underway in a rough sea. The grab handles fitted on the hull topsides, alongside the seat positions, give you that extra sense of security while happily skipping across the waves. Forward of these port and starboard grab rails are RailBlaza, detachable rod holders, while further astern are standard, flush mount rod holders. Anti-skid deck pads extend over all horizontally exposed portions of the hull deck sides, adding to the safety of these relatively high (0.625 m) top sides, when climbing aboard or departing the boat alongside a marina or dock.

Two other notable features to be found At the stern are an extendable S/S boarding ladder on the port side and over the outboard motor is a S/S arched tube which can be beefed up to act as a tow bar or on which can be mounted the detachable bait board, which can be supplied as an optional extra. 

Inside of the boat, now taken care of, let’s look at the unique hull on this 4500. First off, the Cabin model shares the same proven hull as the 4500 Open that we tested a year ago. The hull has a central ‘sponson’ (stability pod) under the wing deck that channels lower and wider towards the transom. This helps smooth the water flow over the propeller to avoid cavitation, which can be an issue for any catamaran with only one engine. Although cavitation is almost non-existent on this boat, even through extremely tight turns; due to the clever hard chine, spray deflecting design. Additional lateral spray deflectors, running smoothly above the lower chine, from the bow and widening gradually towards the stern, also help repel a great deal of water when pounding through waves or in those tight turns. All this making the Cabin 4500 highly manoeuvrable and not surprisingly, even drier than the open model; which wasn’t half bad in this regard. The boat gave us a comfortable ride throughout. The polymer material flexes slightly, softening any hard bangs and deadening the sound, making these much quieter boats than their fiberglass and, especially alloy, cousins,

The new Cabin 4500 gets along really well, especially when fitted with the Honda 60 Hp 4 Stroke, which topped out at about 27 knots on several speed runs conducted at the end of our day’s testing. Although an optional 40 Hp 2 Stroke Parsun outboard will push this boat along at a respectable speed, for the bit of extra money, I’d opt for the 60 Hp unit.

Supplied on a custom galvanised steel trailer, which has been improved with multi rollers instead of skids which, combined with a new additional feature; custom “Floppers” at the back end, lower entry height for beach launching/low gradient ramps. Sitting on the boat while Blair executed the quick and easy retrieve, assisted by the 5:1 manual winch, I was able to witness how these two ‘Floppers” greatly helped sliding the boat onto the trailer. The boat and trailer combination makes one person operation a breeze from start to finish. With a gross weight of 700 kg, as tested, the Cabin 4500 is comparatively light to tow and easy to manage at the ramp; the boat itself weighing only 500 kg.

The FatCats have been out on the market long enough to prove that the hull design and construction are sound. It only remained for Blair to come up with an aesthetically pleasing design and practical solution for attaching the cabin to the existing 4500 catamaran hull to satisfy customer demand.

Suffice it to say, he has succeeded on both counts.
