A 40th is different from a 30th. You probably have kids, a partner you want to look after, and friends across decades you want to mix gracefully. A private boat handles that — quieter than a club, more sophisticated than a backyard, and the photos look incredible. Most 40ths run 4-5 hours with chef catering and a sunset window.
From a $500/hr 4-hour plated catamaran cruise for 18 guests, to a $2,000/hr 5-hour superyacht with full chef service for 40 — Boatique books the full Sydney Harbour fleet. Quotes back in under an hour.
Find Your Perfect Boat
40th party boats lean toward the premium end of the fleet — proper galleys for plated meals, climate-controlled saloons, more refined finish. We’ll match you to boats that suit the mix of friends, family and partner.

Why a 40th on a private boat (instead of a restaurant booking)
🍽 Chef on board, not waiting in line
Most 40ths book chef catering — plated 3-course or buffet — not BYO platters. Means the night feels more like a private dinner than a party.
🥂 BYO premium drinks
BYO that bottle of Penfolds you’ve been saving. Most boats allow BYO drinks — way cheaper than a restaurant wine list, and you get the bottle you actually want.
👨👩👧 Easy with kids and parents
Bring the kids early, drop them home, then the adults stay. Slow pace works for parents-in-law. Sound system handles soft until late, party-mode optional.
📸 The photos you’ll actually print
40th photos on Sydney Harbour with the Bridge in the background are the kind that go on a wall, not just Instagram.
How 40th party cruise pricing works
Most 40ths book at the mid-to-premium end — proper boats, chef catering, longer cruise. The honest pricing answer: a 4-hour 40th for 30 guests on a function vessel with plated 3-course catering and BYO drinks usually lands around $5,500–7,500 all-in.

Frequently asked questions
How is this different from your general birthday party boat hire page?
Our /birthday-party-boat-hire/ pillar covers all ages. This page is specifically for 40ths — boat recommendations and pricing lean to the premium end (plated catering, climate-controlled saloons, etc.). Both can quote the same boats.
Can we book chef catering for a 40th?
Yes — chef catering is the most common format for 40ths. We brief our partner caterers on your boat’s galley constraints, dietary needs, and the kind of menu you want.
Can we BYO drinks?
Yes on almost every boat. Bring your own wines, spirits and beer. The corkage savings cover a meaningful chunk of the boat cost.
Can we bring kids?
Yes — many 40ths bring kids for the first 2 hours, then drop them home before the dinner / late-night portion. Boats with safety nets on the bow and child life-vests are best.
What’s the minimum number of guests?
No minimum. A 40th for 12 guests on a luxury motoryacht with a private chef is a very popular high-end format.
Can we have speeches?
Yes — most function boats have AV setup. Mid-cruise during dinner is the usual slot. We can coordinate with the captain on timing.
Where do most 40ths depart from?
King Street Wharf and Rose Bay are the most common for 40ths — easy parking, walkable from the city, premium feel. Some 40ths depart from Balmoral or Watson’s Bay if guests are based in those areas.
What if someone has dietary requirements?
Our partner caterers handle vegetarian, vegan, gluten-free, halal and kosher with notice. List dietary needs in the quote enquiry — we brief the caterer.
