Seakart - Exciting New Product To Launch at Goodwood Festival of Speed

As a company, Go Earth are all about innovation, having developed new services and new products, and bringing different ways of thinking into the leisure boating market.

We have introduced a unique set of services to the marketplace, all with the aim of helping the boat buyer. We have also introduced a unique automatic fender system that deploys and lifts your fenders on, literally, a touch of a button. We are delighted to be working with Goodwood Festival of Speed again, developing the very successful marine parts of the show.

Now we have another exciting piece of news...

Searific are having the UK launch of their Seakart at the prestigious Goodwood Festival of Speed. We love the Seakart as it combines two things that we are passionate about and are in line with the ethos of Goodwood – boating and speed! It is a unique hybrid - combining the speed and excitement of a jet ski with the safety and comfort of a RIB.

This article, therefore, is a first look at the Seakart now that it is coming to the UK.

The Background

The background to the UK launch is one of those fortunate events.

Searific Marine Distribution Ltd is a family run business founded by Simon Duke.

Whilst on holiday in Mauritius, Simon and his wife, Claire, saw the Seakart advertised as a tourist experience and immediately saw the wider potential of the Seakart in the UK. It was one of those ‘eureka’ moments when you see a product – whether a new product or a development of existing concepts – and it just looks right.

Having always had a keen interest in watersports and boats, Simon seized the opportunity to contact Seakart ’s owner and started conversations about bringing Seakart to the UK.

Searific Marine Distribution is the only official UK authorised Distributor for Seakart.

Searific have decided that Goodwood Festival of Speed is the ideal UK launch pad for the Seakart, as Goodwood has a unique demographic of visitors who have a strong interest – indeed passion – in interesting vehicles of all types shapes and sizes – including cars, motorbikes, planes and boats. The Seakart is a vehicle for people with passion.

What is Seakart?

I guess by this point in the article, you are now asking what exactly is this Seakart?

A simple answer is that it is a combination of the thrills of a jet ski with the safety and comfort of a RIB. This recreational craft is ideal for a family wanting a fun weekend small boat, or a yacht owner looking for a cross between an entertaining watercraft and a tender. It can give either the thrills of a kart (note, please, as any karting enthusiast will tell you, it is a ‘kart’, not a ‘go-kart’!) on the water or the calm relaxation of a family outing.

The advantage of a multi-purpose vehicle like the Seakart is that – unsurprisingly – you can use it for many different purposes, in many different ways.

The Seakart 335 (to give it its full name) is homologated as a category C boat. The RCD definition of a class C is that it is a vessel built to navigate inshore such as lakes, rivers, bays and close to the shore and can sustain up to force 6 and waves up to 2 meters. This makes it suitable for inland waterways (subject to any speed restrictions), as a tender for a superyacht, as a safer alternative to a jet ski, as a fun RIB, or just to take out for a fun ride.

The Seakart also allows you to access beaches easily and stop for swimming breaks whenever the mood strikes. Its powerful waterjet engine, with a shallow draft, makes the Seakart incredibly versatile, allowing you to operate it in shallow or deep waters.


Safety, of course, is important.

Unlike a jet ski, the Seakart 335’s passengers aren’t seated in line. In the event of a mishap, the fiberglass parts and inflated tubes around the vessel create a protective cocoon, helping ensure that the driver and other passengers are safe. As the Seakart is also suitable for all seas up to 2m, you can enjoy an exhilarating adventure whether the water is calm or (within reason) rough.


Given that the Seakart is being launched at the Festival of Speed, then a word or two about speed is inevitable.

Top-notch performance, together with safety, was a priority for the designers of the Seakart. They have powered the Seakart with an economic and reliable Yamaha jet engine – so no potentially dangerous rotating propellers to contend with (or indeed, nothing for any loose lines to wrap themselves around.)

All this together gives the Seakart a top speed of up to 65mph, depending on the engine options of either a 110 bhp or 180bhp engine.

The aim is whether you’re accelerating to achieve maximum speed or slowing down to explore the ocean and surrounding scenery, the Seakart 335 gives a fast, fun thrill ride.


Yes, comfort matters as well.

Although the Seakart 335 is compact, it’s designed to be both ergonomic and spacious. It comfortably seats up to 5 people. Three are seated at the stern; and two slightly forward of midships.

It is also designed to be incredibly easy to operate. It gives you power and control - control is completely yours so that you’ll always feel comfortable and in charge.

It might be small, but it’s a potentially aggressive craft offering boating almost without limits.


Although it is called a 335, the actual length is 3.5 metres, with a beam of 2 metres. The dry weight is 430kg; so is easily towable behind most vehicles.

There is a choice of two 4 stroke, petrol engines giving either 110 hp with maximum speed of 45mph or a massive 180 hp with a maximum speed of 65mph.

Importantly, the tubes are Hypalon - which, as I am sure that you know, is chlorosulfonated polyethylene (CSPE) synthetic rubber (CSM)! Hypalon is rightly regarded as the best material for this type of application, and the better RIBs all tend to standardise on this material.

Key Features

What else do you get? Each Seakart comes with:

    • Under seat storage
    • A 12 v DC socket
    • Upholstered seating
    • Piped deck drains
    • Automatic fire extinguisher
    • Speedometer
    • RPM gauge with a digital hour meter
    • Fuel gauge
    • Behind steering wheel paddle accelerator
    • Bathing Ladder


The Seakart is certainly a new generation of small vessel that is notable for its flexibility of use. It would not be out of place on the back of a small trailer or in the tender garage of a superyacht. However, its real place is, of course, out on the water.

Have fun!
