Common Questions 

Q: What are the boats made of?

A: Rotomoulded Polyethylene. Stiffened and strengthened where necessary. We use the highest PE composition available allowing us to reduce wall thickness in order to minimise weight while maximising strength. Polyethylene is quiet in the water, resilient to scratches, low maintenance, easy to repair & recyclable.

Q: Do they hold their colour in the Sun?

A: Yes. The materials used are fully UV stabilized. 

Q: Where can I see one?

A: Come to our factory/showroom in Auckland or visit one of our dealers. If you're out of Auckland, we have various owners throughout the country who are often happy to show their boat to interested people. Please email us and we may be able to put you in touch with someone much closer to you.   

Q: Can I buy a just a Hull or a Hull/Trailer only

A: Yes although we like to sell as a package to ensure everything is set-up correctly. Contact us for pricing. There are some trailer requirements to keep the hull in warranty. 

Q: What is the warranty on the boat?

A: 3 Year Structural Warranty for recreational use. 

Q: What is the Maximum Horsepower and/or Transom weight?

A: 40Hp or 100kg. Whatever is less.

Q: Can I put a different Brand of Motor on?

A: Yes absolutely. We can supply and fit most brands.

Q: I want some options that are not on your list. Can you build/fit other things?

A: Yes. Get in touch with us to discuss.

Q: Are Catamarans different from monohulls to drive?

A: Yes.

The FatCat 4000 slides on to the plane easily with minimal bow lift. At speed, the crew can sit back without the hull dragging its stern or the bow rearing into the sky.


The Fatcat 4000 remains stable through the roughest seas. It is not nearly as prone to broaching or tipping like equivalent length mono hulls. At high speed in a beam sea the FatCat 4000 gives amazing confidence to the skipper because it remains flat and stable.

Q: How does a FatCat handle different sea conditions?


Rough Seas

  • Stable and flat the whole time


Head Seas

  • Fine bows make for minimal resistance which means a smoother ride


Following Seas

  • A wide foot-print makes the boat stable and reluctant to broach


Crossing a Bar (In suitable conditions)

  • Its quickness on to the plane, handling capabilities, high sides, plus its stability at both slow and high speeds make it very safe if correct bar crossing principals are followed. 

Q: Why are Catamarans normally more expensive than a similar length monohull?

A: The structure, volume and geometry of a Cat means there are simply more materials required and a greater level of construction complexity in the build. Even things like trailers must be wider and larger. Whilst Catamarans normally cost more than comparable length mono hull, they are more than competitive when space, volume and stability is taken in account (and make for a better boat)


Q: Your boats are rotomoulded polyethylene. I'm more familiar with Fibreglass and Aluminium. What are the relative advantages and disadvantages of Polyethylene (PE)?

ADVANTAGE: Polyethylene is extremely impact-resistant, and we’ll go as far as to say that PE boats are almost indestructible in the normal course of recreational boating. Smash into a rock, jetty, much less a piling, and a PE boat will just bounce right off. 

DISADVANTAGE: Polyethylene isn’t as structurally stiff as fiberglass or aluminium, so PE boats are limited in size. There are only a few over 5.5m and many of the relatively large models require structural hull supports built from different materials.

ADVANTAGE: PE boats are moulded, so like fiberglass boats, they can have hulls with complex shapes and compound curves; decks can have moulded-in compartments; and large accessories like seat bases or consoles can also be moulded. Aluminium boats aren’t moulded, so they tend to have much simpler hull forms and accessories must be secured in place with fasteners.

DISADVANTAGE: Moulding tolerances are not as exact as they are with fiberglass, so items like hatches may not fit as perfectly as they would on a fiberglass boat. Many aluminium boats also have more exact tolerances, even though the parts are fabricated as opposed to moulded.


ADVANTAGE: Waxing and polishing are maintenance chores of the past when you own a PE boat. A scrub brush and soapy water is all that's needed to get the boat looking as ship-shape as possible.

DISADVANTAGE: PE boats sometimes don’t look quite as “sharp” as well maintained fiberglass boats because they don‘t have a glossy gel coat. Some modern painted aluminium finishes also out-shine plastic but an un-cared for PE boat will still look good.


ADVANTAGE: Polyethylene boats are often considered more environmentally friendly than fiberglass and aluminium, since they can be recycled and they do not require treatment to prevent marine hull growth.

DISADVANTAGE: Rotomoulded PE boats are not as "fair" as fibreglass boats. Meaning when you look along the panels of a PE boat, they will be more wavey. This waviness occurs in the cooling process during manufacture.
