See inside a $4.7 million yacht with a huge master bedroom. The Sunseeker 76 shows you don't need a 100-foot vessel to set sail in luxury.

• Insider went on board a $4.7 million yacht at the Southampton International Boat Show.
• The Sunseeker 76 has four cabins that can sleep up to eight people.

The Southampton International Boat Show is the largest showcase of all things aquatic in the UK.

It's host to a range of watercraft, from jet skis and dinghies to huge motor yachts. Insider went along to the 54th show last month check out some of the luxurious vessels on display.

They included the Sunseeker 76, with upgrades and customizations such as teak decking and a barbecue grill. It'll set you back a mere £3.85 million ($4.7 million).

Step on board to see inside its three guest cabins and huge master suite, plus the view from the flybridge.

One of the highlights of the Southampton International Boat Show was a Sunseeker 76 yacht worth $4.7 million.

It's 77 feet long and has three decks, with four cabins that can sleep up to eight people.

I boarded at the stern, where there was a small outdoor seating area on the middle deck.

Leading up to the flybridge is a narrow staircase, which had me gripping the handrail.

But it's luxurious once you're up there.

The bar area features a barbecue grill, a fridge, and a sink ...

... plus plenty of seats to entertain guests.

Including some comfortable-looking chairs at the helm.

You get a great view of the water from up here, as well as being able to keep an eye on anyone at the bow.

The front features a u-shaped booth similar to the flybridge, as well as some cushioned sun loungers.

The main deck interior is spacious and has a classy decor.

The kitchen has white marble countertops and a Miele oven.

The dining area can seat eight people.

The luxury details reminded me of Dassault's $75 million private jet, the Falcon 10X.

The main deck only feels bigger as you move through to the living area with two comfortable sofas.

Insider/Pete Syme

There's another console here too ...

... and another couch next to it, underneath large windows which would be ideal for a sunny day.

It initially feels a bit cramped downstairs, but corridor space is sacrificed for cabins, and mirrors make it feel larger.

At the bow, you'll find the VIP guest cabin.

Insider/Pete Syme

It's not easy to move around here due to the room's shape and double bed, but there's still space for a small dressing table and plenty of storage...

Insider/Pete Syme

...plus a television to the side, next to the ensuite bathroom.

Insider/Pete Syme

It's one of four bathrooms onboard the yacht. They all come with a toilet, shower, and sink, and are similarly sized except for the master bedroom's ensuite.

On the port side, you'll find the smallest guest cabin which features two twin beds.

And on starboard, another guest cabin with a double bed...

Insider/Pete Syme

...as well as a TV, wardrobe, and dressing table, albeit smaller than in the VIP cabin.

Insider/Pete Syme

The size of the biggest cabin surprised me compared to the principal bedrooms on Sunseeker's other yachts on display.

Insider/Pete Syme

There was enough space for this table where you could enjoy a coffee with a view of the water (or in this case another yacht).

Insider/Pete Syme

The dressing table, replete with storage space, made the equivalent feature in the other cabins look tiny by comparison.

Insider/Pete Syme

Set back from the rest of the room, you'll also spot plenty of closet space...

Insider/Pete Syme

...which leads round to the bathroom...

Insider/Pete Syme

...which has two sinks. This cabin felt more like being in a hotel room than onboard a vessel.

Insider/Pete Syme

We're used to ogling superyachts with all the bells and whistles, like helipads. But these smaller yachts show the wide range of luxury boating.

I stepped on board a yacht for the very first time, a sleek Champagne-colored vessel for sale at an undisclosed price. Here's a look inside the 150-foot, Bugatti-designed superyacht.
