About GP Engineering Ltd

History of Wavebreak Rigid Inflatable Boats

Grant Parkins, Boat BuilderFrustrated by a market filled with hard-riding, cramped rigid inflatables, Grant Parkins of GP Engineering decided it was time to design and build a RIB that would satisfy the most discerning customer = himself.

An avid outdoor sportsman and highly-experienced marine engineer, Grant knew what features were vital to ensuring high-performance handling, passenger comfort and safety, room for diving, fishing and hunting gear, and flexible configuration to accommodate various activities.

In 1996 he launched his first hand-crafted alloy-hulled rigid inflatable boat and he named her, Wavebreak.

Best RIB in its Class

GP Engineering has been designing and building Wavebreak Rigid Inflatables ever since. Through the years we have perfected the hull and incorporated innovative design features to achieve what many believe is the best RIB in its class.

Designed to provide optimal room and stability, Wavebreaks endure rugged treatment without compromising rough water performance or safety.

Our RHIB models include Bare (tiller-style), Centre-Console, Sport, Jetboats and Outboard Jet Boats, Blue-Water Cruisers and Offshore Series.

All custom-built, Wavebreaks range from 3M tenders to 11.5M launches

Built in Nelson NZ since 1996!

Buy NZ Made!Wavebreaks are designed in New Zealand and built in New Zealand. Our RIBs are not mass-produced elsewhere and imported into the country under a NZ-designed logo.

Each and every Wavebreak is individually constructed by Grant Parkins in our workshop in Nelson. This ensures superior-quality construction and allows for complete customization.

Our hands-on approach and accessibility enables customers to talk directly to us before, during and after construction and delivery.

Maritime Operator Safety System (formerly Safe Ship Management) Compliant

Maritime Operator Safety System (formerly Safe Ship Management) CompliantThe Wavebreak's superiority is proven: Maritime Operator Safety System Build Certification is available for coastguard, rescue, police, tour, boat hire and other commercial operations.

Wavebreaks are built to exceed strict survey standards as administered by Ministry of Primary Industries and other international organizations.

One customer said it best: "You can rely on a Wavebreak."

Exceptional Performance and Quality

Wavebreak Jet Boat powered by 200hp Mercury OptimaxBoth recreational and commercial users agree that the Wavebreak delivers what is promised: our outboard models provide smooth dry rides in rough seas and our jetboats allow fast, confident navigation over rocky riverbeds.

Vital Features for Safety at Sea

We specialise in building MNZ-approved Rescue RIBs and Commercial CrafftReverse chines enable fast planing, sharp cornering and predictable handling; D-shaped pontoons and thoughtful layouts provide uncluttered internal space; wide beam and large pontoons guarantee superb stability both at rest and while under-way.

Thick alloy hulls tolerate bottom impacts; and our "dual-layer" pontoon system with high alloy sides ensure vital safety at sea and durability in rugged conditions.

Superior Design Features

*Top quality 5083 marine-grade alloy hull and sides provide up to 600mm freeboard
*High sides enable boat to remain operational even with fully-deflated pontoons
*Large D-shape pontoons free up internal floor space and provide excellent stability
*Puncture-resistant "dual layer" pontoon system is safer than single systems including Hypalon
*Removable heavy-duty bladders are encased by durable rip-stop outers

Wavebreaks = Fish Magnets

7.3kg = 16lb !  That's a huge fish!!

Simon caught this 7.3kg snapper off Great Barrier Island, New Zealand.

Hmmmm, the spearos have captured something big... What is it?!

Holy Schmoly!! It's a 37kg (81.50lb) kingfish! Well done, Buoys!

There's no escaping Garrett when you're a cray and he's in the mood for a feed!

These John Dory were drawn to the Wavebreak Sport, so Grant took advantage and snatched them up with a little bit of squid on a 20lb-test line.

You say Groper, I say Grouper.  Let's all say, dinnertime!The sun was shining, birds were singing and the grouper were chomping in the Milford Sounds, Fiordland. Nice catch, Graeme!

Luke caught the biggest snapper from a secret location (call us for the coordinates! kidding, we won't give them to you.)

Oh, Snap!
