3 hour Dolphin and Seal Swim (NOV-APR)
Port Phillip Bay gives you two very different wildlife encounters in one trip: a close snorkel with Australian fur seals at manmade Chinaman’s Hat, followed by a search for resident dolphins. The best part is the animals set the pace. You may float near seals for a long time, while dolphins might swim around you or simply pass by.
I like the two wildlife stops and the practical setup. Moonraker has a café, bathroom, several seating levels, and snorkeling equipment, so you are not left sorting out the basics on a small open boat. The free repeat offer is another sensible touch if dolphins do not appear, though the stated return window varies between 30 days and three months.
The main consideration is that dolphin swimming is never guaranteed, and water visibility can affect the encounter. Some outings produce close dolphin contact; on others, you may see the pod more clearly from the boat than from the water. At $150.62 per person, this is a fair price for a three-hour wildlife cruise with gear and refreshments, but it makes the most sense if you are happy with a genuine search rather than a promised swim.

Key points to know before boarding

- Chinaman’s Hat comes first: Snorkel in shallow water near Australian fur seals of different ages and sizes.
- Dolphins are wild animals: The crew watches their behavior before entering the water, and each encounter can be short or prolonged.
- Small water groups: Up to 10 people enter the water at a time, helping keep the activity more controlled.
- Moonraker is well equipped: You get snorkeling gear, onboard bathroom facilities, café service, and different levels for sitting.
- Morning or afternoon departures: You can choose the time that fits your Mornington Peninsula plans.
- No dolphins does not always mean no second chance: A free repeat is offered, but confirm whether the applicable window is 30 days or three months.
Setting out from Sorrento Pier

The trip begins at the Esplanade in Sorrento, Victoria, with boarding at Sorrento Pier. You collect your equipment before stepping aboard Moonraker, described as a luxury vessel with room to sit at different levels. That matters on a three-hour trip, since you can change position instead of being stuck in one seat the whole time.
Once the boat leaves the pier, the snorkel guides explain the activities and help you get familiar with the boat. This introduction is useful even if you already snorkel. You need to know how the water entry works, where to return, and how the crew wants you to behave around seals and dolphins.
The advertised maximum is 30 people. That is not a tiny private charter, but it is a manageable group for a wildlife cruise. The dolphin water entry is handled in groups of 10, which limits the number of swimmers around the animals at once.
You can choose a morning or afternoon departure. Check the exact meeting time carefully when booking. One poor experience resulted from confusion between the time supplied by the booking agent and the actual boat departure, creating a long wait before boarding. That problem was tied to the booking information rather than the boat operation, but it is a useful reminder to confirm the final time and arrive at the stated meeting point.

Chinaman’s Hat and the fur seal swim

The first water stop is the shallow area around Chinaman’s Hat, a manmade structure in Port Phillip Bay known for its Australian fur seals. This is the most dependable part of the wildlife program because the seals use the area regularly, and the boat heads there before searching for dolphins.
You enter the water with snorkeling equipment supplied by the operator. The seals can be inquisitive, and you may find yourself face to face with animals of different ages and sizes. The appeal is not just seeing a seal from a distance. You are floating in the same water and watching how the animals move around the structure.
The shallow water also helps make this section feel more approachable. You are not being asked to swim far into open water before you know how the equipment feels. The guides walk you through the activity, and most people who can participate in the tour should be able to take part in this section, provided they are comfortable in the water.
Still, keep your expectations sensible. The seals are not trained performers. They may come close, inspect the swimmers, or keep their distance. Their behavior is part of the attraction, and the crew must avoid changing their normal habits.
This is where the tour’s strongest value appears. A standard bay cruise might offer wildlife viewing from the deck, but this outing gives you the chance to snorkel near the seals. The combination of shallow water, supplied gear, and guide support makes Chinaman’s Hat a strong reason to book even if dolphins never cooperate.
Lunch, cake, and a pause on Moonraker

After the seal swim, you return to Moonraker for food and a break. The itinerary describes lunch, while the onboard service is also presented as a café with drinks and cake. The exact meal details are not given, so think of this as included onboard refreshment rather than a full restaurant meal with a stated menu.
The pause has a practical purpose. You have time to warm up, change your focus, and regain energy before the dolphin search. The boat’s bathroom is useful here, especially on a three-hour trip with water activity. Different seating levels also give you options between stops.
One of the more positive details is the tone of the crew. Staff are described as friendly, safe, professional, and attentive. Those qualities matter more on a wildlife swim than polished commentary. You want clear instructions, calm handling of the group, and staff who watch both the swimmers and the animals.
Bring clothing suited to the weather, as instructed. Conditions on the bay can change the feel of the trip, and you will spend time both in the water and on deck. The operator may cancel in poor weather, in which case you are offered another date or a full refund.
Searching Port Phillip Bay for dolphins

The second half of the trip is less predictable. The dolphins are resident to Port Phillip Bay, but resident does not mean guaranteed contact on every departure. The crew searches for the pod, then watches its behavior and position before deciding how to proceed.
That waiting and watching is important. The dolphin swim is not a simple stop where everyone jumps in on a fixed schedule. The crew aims to avoid changing the animals’ behavior or lifestyle, so the boat approaches with care and enters the water only when conditions are suitable.
Once the dolphins are located, small groups of 10 slide into the water and float on the surface. You wait quietly for the dolphins’ squeaks and whistles to become louder, which can signal that they may come closer and swim with the group.
The encounter can vary widely. Dolphins might circle the swimmers for an extended time, or they may glide past for a look and continue on. Sometimes they are easier to see from Moonraker, where you have a broader view and can follow their movement without water visibility getting in the way.
This is the section that demands the most patience. If your main goal is a guaranteed close dolphin swim, the uncertainty may frustrate you. If you value responsible wildlife viewing, the limits are a positive sign. The crew is not promising a staged performance, and the animals are allowed to decide how much contact they want.
The dolphin swim also depends on visibility. One account describes the boat viewing as better than the in-water view, while other outings have produced many dolphins and close activity. That contrast is normal for a wild encounter. Entering the water does not automatically give you the clearest view.

What $150.62 buys you

At the listed price of $150.62 per person, you are paying for roughly three hours on the water, the chance to snorkel with seals, the dolphin search, equipment hire, guide support, and onboard facilities. Lunch or refreshments are included in the outing, though the exact food offering should be confirmed if that matters to you.
The value is strongest when you count the whole day as a wildlife program rather than a dolphin-only ticket. The fur seal stop provides a substantial encounter on its own. The dolphin search then adds a second chance for a memorable moment without charging a separate fee for snorkeling equipment.
The free repeat policy improves the value if dolphins are not seen. However, the information gives two different limits: one says you can return within three months, and another says within 30 days. Confirm the exact period before relying on this option, especially if your Mornington Peninsula visit is short.
The price is less attractive if you want a guaranteed swim with dolphins and would be disappointed by boat-only viewing. No wildlife operator can control the pod, and this trip is honest about that uncertainty through its repeat offer and behavior-first approach.
With more than 20 bookings recorded in the previous month and a 4.2 rating from 43 reviews, the tour has clear demand and generally positive feedback, but it is not perfect for every departure. The strongest praise centers on the crew, the roomy boat, the seals, and occasions when many dolphins play near the swimmers.
Who will enjoy this Mornington Peninsula tour

I would recommend this to anyone who wants an active wildlife outing rather than a passive sightseeing cruise. You should be comfortable wearing snorkeling gear and entering the water, or at least willing to try with guide support.
It suits couples, families with older children, and visitors building a Mornington Peninsula day around Sorrento. Children must be accompanied by an adult. The maximum group size of 30 keeps the trip from becoming a huge boat excursion, while groups of 10 in the water make the animal encounters more orderly.
It is also a good fit if seals interest you as much as dolphins. Chinaman’s Hat offers the more reliable wildlife contact, and the seals can be very engaging. If you are booking only for the dolphin swim, read the conditions carefully and accept that the pod may not approach.
Choose your departure time based on the rest of your day, but check the confirmed time closely. The meeting point is near public transportation, and the tour returns to the same location at the end.
Practical details that affect the day

Confirmation is provided at booking. Wear clothing suited to the weather, and remember that the tour requires good conditions. If poor weather cancels the trip, you can choose another date or receive a full refund.
Cancellation is free when made at least 24 hours before the start time. Changes or cancellations within 24 hours are not accepted for a refund, and the cut-off follows local time.
The boat has a bathroom and café facilities, but the supplied information does not list a full menu or say exactly what lunch includes. If you have dietary needs, check before departure.
Snorkeling equipment is provided. The guides explain the activities onboard and organize the dolphin entry in groups of 10. Most people can participate, but the activity still involves swimming and floating in bay water, so consider your own comfort and ability before booking.
Should you book the Moonraker dolphin and seal swim?

Book it if you want a well-supported chance to snorkel with Australian fur seals and search for wild dolphins in the same three-hour trip. The seals, professional crew, roomy boat, supplied equipment, bathroom, and repeat option give the outing solid value.
Think twice if a dolphin swim is your only acceptable outcome. The dolphins may stay near the boat, pass quickly, or be hard to see underwater. The better approach is to treat dolphin contact as a welcome extra and Chinaman’s Hat as a major part of the day.
For most active visitors in Mornington Peninsula from November through April, I would book, but I would confirm the departure time and the exact free-repeat window first. Go ready for a real wildlife encounter, not a guaranteed photo opportunity.
