Reviews from actual guests!

I recently had the pleasure of booking XTsea for my friend’s Buck’s party in Sydney, and I couldn’t be happier with the experience! We went with the catering option and I am very glad we did. We had lots of yummy food and the staff were able to cater for our dietary requirements. The friendly staff, beautiful boat and the breathtaking views made for a day out that my friend group will never forget. I would highly recommend.

David and Colleen were great hosts! We had a group of about 20 and they made it so easy by preparing our drinks on ice and food on the BBQ! They catered to all of our requests. Our favorite parts were swimming on the Lillipad and the harbour cruise! Very experienced and professional. Thanks!!

We had an absolutely amazing charter with Colleen and David on XTsea! No request was too hard for them, they were so easy to deal with at every step of the way in planning and ensuring we had the best experience with our charter. They were also such great hosts on the day. Could not recommend more!

XTSea is the perfect boat for a party on the harbour. Skipper Colleen and her husband Dave are super-professional and easy-going, the sound system is top-notch, there’s heaps of space for 20-30 people, and the eskis are huge and filled with ice!

Points of difference

There are plenty of charter boats in Sydney. Why should you choose XTsea?


XTsea boasts a stunning 2000W audio system pumping into 11 speakers. A 10 inch subwoofer gives the music a depth that will make you think you are front row at a rock concert. If you want it loud, it'll be loud!

Full Service

We always run a two-person crew and we do all the work so you can enjoy yourself. We do all the cooking and make sure everything runs smoothly. All you need to do is grab yourself a drink and just have a great day.

Watertoys. All FREE.

Fancy getting wet? We have on board the largest-sized Aqua Lilypad, a Hobie Stand-up stepperboard, a Stand-up paddleboard, and a one-person kayak. All toys are provided absolutely FREE!

Free Ice!!

We provide ice free to all charters! You don't have to lug melting bags of ice to your event because we do it for you. That's right.. FREE.

Tender available

We have a 3.2m tender which we use when needed. Late guests arriving? Guests leaving early? Shoe floating away? RIB to the rescue!

Free Water!!

We have beautiful chilled filtered fresh drinking water readily available on-tap. This reduces our plastic refuse and saves you expense and effort.

Curly the furbaby

Pets? We love 'em!

Your well-behaved furchild or companion animals can come and enjoy the day with you! You'll be responsible for their behaviour and safety, and make sure other guests are okay with them. Be prepared for your animals to be spoiled rotten and cuddled mercilessly by the pet-deprived crew.


We do everything we can to keep our eco-footprint as small as possible. Instead of cheap single-use plastic cups and plates we provide quality durable items. You'll have access to beautiful filtered drinking water from a tap instead of bottles, and everything electrical runs on solar instead of a generator.

LGBTQI+ welcome

We celebrate diversity and love nothing better than Kylie, Cher, or Lady Gaga bangin' on our sound system. Your lifestyle is your choice and we welcome you to celebrate on board with us in whatever way makes you happy. Some of our best events on board have been LGBTQI+ parties so bring it on!


Our calendar is available online 24/7 and is ALWAYS up to date. Click on the link to see what’s available.

If you are our first charter of the day, you get to pick the time! Unlike most charter boats, we don’t try to lock you into a time that suits us. Other bookings we get for the day will have to work around you!

Our maximum capacity is 30 guests and two crew, but that’s a very crowded boat if the weather isn’t great. If you are worried about rain you might like to limit yourself to 20-25 guests or so to make things more comfortable.

We can pickup or dropoff practically anywhere. As well as the popular Darling Harbour points, we can use any ferry terminal and even public jetties. Pick a spot that’s convenient to you and your guests and we’ll figure something out.

We don’t hold a liquor licence so you can supply your own drinks (at bottleshop prices!) and you can bring whatever you like. Spirits are not a problem, but if you are intending to have a lot of alcohol available you’ll need to supply an appropriate amount of food.
You can also arrange for drinks to be delivered to us beforehand by any of the online retailers.

Vaping is allowed OUTSIDE but smoking is not permitted.

Yes. Yes we do. Free ice and free chilled drinking water for all charters. You don’t have to lug extra weight to your party!

No. We supply absolutely everything except your food and your drink. We supply quality, sustainable drinkware.

You will be required to remove any footwear before boarding. We roll out the red carpet and you drop your shoes in a tub as you board. At the end of the charter your shoes are laid out in pairs to make things easy.

We have an enormous AquaLilypad swimmat, two Hobie Stepperboards (massive fun, easier than a paddleboard and so stable!) and a single person kayak.

All our toys are completely FREE to use.

Our advice is that there isn’t any spare vertical spaces to hang decorations, and trying to put up anything in a crowded boat is going to be a challenge. Usually decorations are returned at the end of the charter unopened, so save yourself some money and time and don’t bother.
Balloons are definitely discouraged. There is no space for them and they are very detrimental to the marine environment.

ABSOLUTELY NO SPARKLERS!! Sparklers spray off tiny pieces of molten metal which cause immense damage to the plastic coating of a boat. Candles we can handle as long as they are simple flames.
Unless you have a bunch of teenage kids, cakes generally don’t work too well on a boat. After a few drinks, the last thing people want is a piece of cake. However if you decide you do want a cake, we provide plates and servingware and after the guest of honour performs the first cut, we will expertly plate out the cake for you.

Awesome! How do I book?

It’s so easy to make a booking with XTsea. Our calandar is always up-to-date and you can see our availability 24/7. If we have a time open that suits you, just start the conversation by email or phone or text. We’ll discuss the options and help you plan what’s best for your event and pin down all the details. A deposit of 20% will secure your booking, and you’ll find our conditions very generous if things change for you.
The summer season is incredibly popular and most boats will be completely booked out for popular days four months in advance. Plan your event EARLY!
