Two questions bring people to this page. Which are the biggest boats at the Perth Boat Show 2026, and does size actually matter when you are choosing a boat — or is it just spectacle? Both deserve straight answers, because the answer to the second decides how you should spend your hours in the halls.

The short version first. Motoryachts Australasia’s display is set to be the biggest boats at the show: the 17.13-metre Sunseeker Superhawk 55 and the 12.4-metre Saxdor 400 GTS, the first of its model in Western Australia. Both will be on display at the Perth Convention and Exhibition Centre, 21 Mounts Bay Road, from Friday 4 to Sunday 6 September 2026.

As for whether size matters — it does, but not for the reason people assume. A big boat at a show is not there to impress. It is there because size is the one thing a photograph cannot show you, and standing aboard is the only honest way to judge it. This article explains what to look for, what else the show holds, and what to do about the boats too big for any exhibition hall.

What size actually buys you — and why photos hide it

Every boat looks roughly the same size on a screen. A phone photo of a 12-metre boat and a 17-metre boat, each framed to fill the shot, tells you almost nothing about the difference between them — and the difference is the whole point. Boarding is the only way to measure the things that decide whether a boat suits how you will actually use it.

  • Interior volume. Length is the headline figure, but usable volume grows with beam and headroom as well, and it grows much faster than length alone. The Superhawk 55 carries a 4.93-metre beam; the Saxdor 400 GTS a 3.55-metre beam. What that means inside a saloon or a cabin is something you feel within seconds aboard and never from a brochure.
  • Cabin count and layout. A floor plan shows two cabins; it does not show whether the second cabin takes an adult comfortably or whether the en-suite works at sea. Walk through with the people who will actually sleep aboard.
  • Deck space. Cockpits, side decks, swim platforms and sunbeds are where Western Australian boating actually happens. Stand on them. Rehearse the moves you will make every trip — helm to bow, galley to cockpit, stepping aboard with your hands full.
  • Systems and tankage. Bigger boats carry more plumbing, more electronics and bigger tanks — the Superhawk 55 holds 1,800 litres of fuel and 430 litres of fresh water — and those figures shape how far you go and how long you stay out. On the MYA stand you can put systems questions to the team that services these boats as well as sells them.

None of this requires a deposit. It requires an hour in the halls with the boats open and staff free to talk — which is exactly what a boat show is for.

The biggest boats expected in the halls

At 17.13 metres, the Sunseeker Superhawk 55 is expected to be the biggest boat at the show. It is an open sports yacht from Sunseeker’s performance series: twin Volvo Penta IPS 950s — 725 PS each — driving pod propulsion for up to 38 knots, a sociable aft cockpit with a wet bar, and an open-plan lower deck with two cabins and two en-suites. Displacement is 26,100 kilograms, beam 4.93 metres, draft 1.43 metres. We have written a full guide to what to inspect aboard in our Superhawk 55 show preview, and the builder’s figures are on the Superhawk 55 model page.

Alongside it, the Saxdor 400 GTS makes its WA public debut — the first of the model in the state. It is a 12.4-metre open walkaround with a glass-shielded helm, folding side terraces, convertible sunbeds and modular seating, rated for up to 850 horsepower of Mercury V8 and V10 outboards and up to 50 knots on its twin-stepped hull. The full story of the boat and its debut is in our Saxdor 400 GTS show article; specifications are on the 400 GTS model page.

The two make a useful pair precisely because they are different answers to the size question. The Superhawk is the volume answer: weight, cabins, en-suites, tankage and pod drives. The 400 GTS is the speed answer: outboard power, a stepped hull and a deck that converts between fishing, swimming and entertaining. Walking from one to the other in a few minutes is exactly the comparison a show exists to make easy.

One honest caveat, because we would rather earn trust than a headline: other exhibitors’ line-ups are not published at the time of writing, so “biggest” is expected rather than settled. What is settled is the boats themselves — 17.13 metres and 12.4 metres are the builders’ own figures, and both boats will be open to walk through.

The rest of the show: six pavilions, 80-plus exhibitors

The top end is one slice of the show, and deliberately so. Across Pavilions 1 to 6, the Perth Boat Show 2026 brings together more than 80 exhibitors, and the range runs from family trailer boats to high-performance craft, with marine technology, on-water gear and marine services alongside the boats. If you are weighing a big boat against the alternative of a smaller one — a genuinely sensible comparison — the show puts both ends of the market under one roof on the same day.

The practical details, condensed:

  • Dates and hours. Friday 4 September, 9.30am to 7.00pm; Saturday 5 and Sunday 6 September, 9.30am to 5.00pm. Sunday is Father’s Day.
  • Venue. Perth Convention and Exhibition Centre, 21 Mounts Bay Road, Perth.
  • Tickets. Adults $22.50 online plus a booking fee, or $26 at the gate; children five to fifteen $10; under-fives free. A family pass — two adults and two children — is $55 online plus booking fee and valid Friday and Saturday only. Friday evening entry from 3.30pm is $12.50 plus booking fee for adults and concessions.

If you want unhurried time aboard rather than a shuffle through, the Friday session is worth considering — the show trades until 7pm that day, with discounted entry from 3.30pm. Our full Perth Boat Show 2026 guide covers times, tickets and what to see in more detail, and the organisers publish event and exhibitor information at perthboatshow.com.au.

Bigger than any hall: the range runs to roughly 134 feet

Here is the part of the size story a show cannot tell. The Superhawk 55 sits near the bottom of the Sunseeker range, which at the time of writing spans approximately 55 to 134 feet across about 19 models. No exhibition hall holds a 134-footer; yachts at that scale are viewed at Motoryachts Australasia’s base at Rous Head Harbour in North Fremantle, where viewings are arranged seven days by appointment.

So treat the show as the entry point rather than the whole catalogue. If the Superhawk 55 feels like the right idea at the wrong scale, that conversation continues in North Fremantle with the larger models in the Sunseeker range. The boats currently available to view or order in WA, across both brands, are best checked against the current fleet, which changes as vessels arrive and sell.

The same logic runs down the range, too. The 400 GTS at the show is one of three Saxdor 400s — the open GTS, the enclosed-wheelhouse GTC and the open-wheelhouse GTO share the same 12.4-metre platform — so an hour aboard the GTS is also groundwork for choosing between the three.

Start with the biggest boats on the floor

If size is on your shortlist — or you simply want to calibrate what 17 metres feels like before deciding whether you need it — the Motoryachts Australasia stand is the place to start. The Superhawk 55 and the first Saxdor 400 GTS in WA will both be open to walk through, with the MYA team aboard to answer the specific questions: layouts, systems, servicing, and what ownership at each size actually involves in Western Australia.

Buy tickets through the official Humanitix page — online prices carry a booking fee — and check the show’s website for exhibitor details before you go. If you would rather talk before the show, or the boat you have in mind is bigger than anything a hall can hold, call Motoryachts Australasia on +61 499 770 180 or reach the team through the contact page. Viewings at North Fremantle run seven days by appointment — before the show, and after it.

Frequently Asked Questions

What are the biggest boats at the Perth Boat Show 2026?

Motoryachts Australasia's display is set to be the biggest boats at the show: the 17.13-metre Sunseeker Superhawk 55, an open sports yacht with twin Volvo Penta IPS 950s and a top speed of up to 38 knots, and the 12.4-metre Saxdor 400 GTS, the first of the model in Western Australia. Other exhibitors' line-ups were not published at the time of writing, so treat biggest as expected rather than confirmed. Both boats will be open to walk through at the Perth Convention and Exhibition Centre from 4 to 6 September 2026.

When and where is the Perth Boat Show 2026?

The show runs Friday 4 to Sunday 6 September 2026 at the Perth Convention and Exhibition Centre, 21 Mounts Bay Road, Perth, across Pavilions 1 to 6. Doors open at 9.30am each day; Friday trades until 7.00pm, Saturday and Sunday until 5.00pm. More than 80 exhibitors cover everything from family trailer boats to high-performance craft, alongside marine technology, on-water gear and services. Sunday 6 September is Father's Day. Tickets are sold online through Humanitix, and the organisers publish event and exhibitor details at perthboatshow.com.au.

Why does boat size matter when choosing at a boat show?

Because size is the one thing photographs flatten. Usable interior volume grows with beam and headroom as well as length, so two boats that look similar on a screen can feel completely different aboard. Standing on the actual boat lets you judge whether cabins take adults comfortably, whether decks suit the way you fish, swim or entertain, and what the tankage and systems mean for time away from the marina. Ten minutes aboard the 17.13-metre Superhawk 55 and the 12.4-metre Saxdor 400 GTS tells you more than any brochure, which is the strongest reason to visit in person.

Can I see Sunseeker yachts bigger than the Superhawk 55 in Western Australia?

Yes, but not in an exhibition hall. At the time of writing the Sunseeker range spans approximately 55 to 134 feet across about 19 models, and the Superhawk 55 sits near the bottom of it. Yachts at the larger end are far beyond what any pavilion can hold, so they are viewed at Motoryachts Australasia's base at Rous Head Harbour in North Fremantle instead. Viewings are arranged seven days by appointment through the office on +61 499 770 180, before or after the show.

How much do Perth Boat Show 2026 tickets cost?

Adult tickets are $22.50 online plus a booking fee, or $26 at the gate. Concessions are $17.50 online or $20 at the gate, children aged five to fifteen pay $10, and children under five enter free. A family pass covering two adults and two children costs $55 online plus booking fee, or $60 at the gate, and is valid on Friday and Saturday only. Friday evening entry from 3.30pm is discounted to $12.50 plus booking fee online, or $15 at the gate, for adults and concessions. Tickets are sold through the official Humanitix page.
