Private Charter: Customizable Big Island Boat Adventure
Kona’s coast is best seen from the water, where a private boat lets you choose between snorkeling near Captain Cook Monument, searching for dolphins, watching whales when in season, or simply tracing the black volcanic shore. The captain and crew shape the outing around your group instead of running a fixed sightseeing script.
I like the small-group privacy and the crew’s gentle way with mixed-age families. I also like the practical touches: shade on the boat, bottled water, snacks, sandwiches, fresh fruit, and full snorkel equipment. The main catch is the price, which makes the most sense when several people share it, and the afternoon start leaves less flexibility than a morning trip.
Key points to know before booking

- Private Kona coast boat: Your group has the boat and crew to itself, with a four-hour plan that can change with your interests and sea conditions.
- Snorkeling is the main draw: Masks, fins, safety jackets, and wetsuits are supplied, and one group spent close to two hours in the water.
- Captain Cook Monument may be part of the route: The exact stops depend on conditions and what you want to see.
- Simon, Kenny, and Adam have earned strong praise: Their local stories, sea-life explanations, and calm help with nervous swimmers add real value.
- Family groups fit well: The boat has worked for groups with children, grandparents, and parties as large as 15, though the stated age limits need careful checking.
- Plan around the rules: Check-in is at Honokohau Marina at 12:30 p.m., hotel transport is not provided, and cancellation terms should be confirmed before payment.
A private afternoon on the Kona coast

This is not a standard boat ride where everyone follows the same route and schedule. Hang Loose Boat Tours gives your party a private four-hour charter from Honokohau Marina, then builds the afternoon around your priorities.
You might spend much of the time snorkeling, cruise along the black volcanic shoreline, look for dolphins, or watch for whales during the appropriate season. You can also mix these goals, though the captain will need to balance travel time, sea conditions, and the time available at each stop.
That freedom matters most when your group has different energy levels. Strong swimmers can spend longer in the water while someone who prefers the boat can stay aboard in the shade. Families with children and grandparents do not have to match the pace of a large shared excursion.
The listed start time is 12:30 p.m., and the activity returns to the same meeting point. Since hotel pickup is not included, you need to arrange your own ride to 74-381 Kealakehe Parkway in Kailua-Kona. Allow enough time to find the marina and complete check-in, which is scheduled for 30 minutes before the boat portion.

What happens at Honokohau Marina

Honokohau Marina and Small Boat Harbor is the starting point for both check-in and the return. This keeps the logistics simple: you meet the boat there, spend about four hours on the water, and finish back where you started.
The marina portion is not a sightseeing stop in its own right. Think of it as your launch point. Have your group together before check-in, and make sure everyone knows that the boat will not collect you from your hotel.
The operator provides a mobile ticket, and confirmation is issued when you book. The tour is offered in English, though the guide may sometimes be multilingual. If your group needs a particular language, ask before reserving rather than assuming it will be available.
A four-hour route shaped by your group
Once aboard, the day becomes flexible. The captain can help you decide how much time to give each activity, based on what your group wants and what the ocean allows.
For many people, snorkeling will be the centerpiece. The boat carries masks, fins, safety jackets, and wetsuits, so you do not need to bring a full set of gear. One family spent nearly two hours in the water at a snorkel site, while another group visited the waters near Captain Cook Monument.
That does not mean Captain Cook Monument is guaranteed on every departure. Your route is customized, and the captain must consider conditions and timing. Ask at the start what is realistic for the day, especially if a certain location matters to you.
You can also ask to search for dolphins or watch for whales. Wildlife sightings are never promised, but the private format gives your captain more room to respond to what your group hopes to see. If snorkeling is your priority, say so clearly. If you prefer a relaxed cruise and coastal views, that is useful information too.
The black volcanic shore gives the ride a strong sense of place. Rather than seeing only beaches and resort frontage, you get a closer look at the rugged Kona coast from the water. The boat’s route and the captain’s local commentary help turn the coastline into more than a backdrop.
Snorkeling gear, food, and comfort aboard
The included equipment is a real convenience. You receive snorkeling gear, safety jackets, and wetsuits, which cuts down on packing and rental errands. If you already have equipment that fits you well, you can still ask the crew about using it, but the provided gear covers the basics.
The boat also carries bottled water and snacks. Lunch includes sandwiches and fresh fruit, a welcome touch on a four-hour outing. Special diets are not covered by the provided meal, so you should bring your own food if you have specific requirements.
Comfort can matter as much as the scenery on a private charter. One group specifically appreciated the shade on the boat, and another noted that the boat remained comfortable even when the ride out was a bit rough. That said, the sea can still feel active. If you are prone to motion sickness, plan accordingly, although no medication advice is supplied with the tour details.
The crew can adjust the experience for people who are hesitant in the water. In one especially useful example, a young boy tried snorkeling, became scared, and returned to the boat. The guides kept him involved, offered encouragement, and gave him time to decide what he wanted to do. He eventually returned to the water and enjoyed himself.
That is a good sign for families, but you should still be realistic. A private boat does not remove waves, wind, or water anxiety. Children must stay with an adult, and the stated minimum age is four.

The crew makes the difference
Simon, Kenny, and Adam are the names most worth knowing before you go. The crew has been praised for careful navigation, local explanations, and stories about Hawaiian folklore. That kind of guiding can make a quiet stretch of coast or a snorkel stop feel more meaningful.
I especially value the crew’s role when a group has mixed abilities. They are not there only to drive the boat and hand out masks. The experience includes help with the water, conversation for people staying aboard, and explanations of coastal and underwater life.
A private setting also makes it easier to ask questions. You can ask about the volcanic shore, the sea life you see, or the places along the coast without competing with a large crowd for the guide’s attention.
The wording about the captain and crew should not lead you to expect a fixed team on every departure. Simon, Kenny, and Adam have been associated with the outings described, but the specific crew may vary. If a particular guide matters to you, confirm that before booking.
Who gets the best value from the price

The listed price is $1,882 per group, with capacity options that may cover 10, 15, 24, or up to 48 passengers. The booking information also says to book one adult for a voucher, so this is not priced like an ordinary per-person excursion.
That price is hard to justify for one or two people. It becomes more reasonable when divided among a family reunion, wedding group, or extended family party. A group of seven, for example, gets a private boat, crew, food, gear, and a custom route without sharing the afternoon with strangers.
The value comes from control. You are not paying only for four hours on a boat. You are paying for a private schedule, room for different swimming abilities, the chance to request specific activities, and a crew focused on your group.
Still, compare the price with your group size before you reserve. The product information uses several capacity levels, and the headline price says per group up to one, which is confusing. Confirm exactly how many people your chosen option covers and what the final total will be.
Age limits and family planning

The activity states a minimum age of four and a maximum age of 65. That upper limit is unusual for a family charter, especially since one account describes a group ranging from age 11 to 76. Because those details do not line up, you should ask the operator to confirm the current age policy for everyone in your party.
The boat has suited groups with young children, adults, and grandparents, but each person should judge their own comfort with a four-hour outing at sea. The crew can support a nervous child, yet no guide can guarantee that every child will want to snorkel.
Advanced pregnancy is listed as a reason not to take the tour. Most people can participate, but you should provide accurate ages and relevant health information at booking so the operator can advise you properly.
What to bring and how to prepare
Bring a swimsuit, sun protection, and any special-diet food you need. The operator supplies water, snacks, lunch, snorkel equipment, safety jackets, and wetsuits, so you can pack lighter than you would for a self-guided water day.
Wear clothing that can handle spray and bring a dry change if you have room. The supplied information does not promise storage, towels, or hotel transport, so avoid assuming those extras are available.
Your group should also agree on its main goal before boarding. If everyone wants snorkeling, tell the crew. If some people want wildlife searches and others prefer a coastal cruise, mention that early so the captain can plan a fair mix.
Timing, weather, and cancellation details
The scheduled start is 12:30 p.m., with check-in at Honokohau Marina. The tour lasts about four hours and ends at the same meeting point.
Weather matters. If poor conditions cancel the outing, you are offered another date or a full refund. For a normal cancellation, the supplied policies conflict: one section says seven days before departure for a full refund, while another says you can cancel at least 24 hours before the start time. Confirm the current rule directly when booking, and save the written terms.
The 24-hour policy says changes or cancellations inside that window are not accepted and are not refunded. Cutoff times use local Hawaii time.
Is this charter right for you?
Book it if you have a sizable group and want a private Kona coast day with a flexible plan. It is especially well suited to families who need space for children, older adults, strong swimmers, and people who may prefer to stay aboard.
I would also choose it if snorkeling near Captain Cook Monument, dolphin searches, local folklore, and a close look at the volcanic shore all sound appealing. The crew’s personal attention is one of the strongest reasons to pay for a private boat.
Think twice if you are a couple or a very small party facing the full group price. A shared excursion may cost less. Also confirm the age limits, passenger capacity, crew availability, and cancellation deadline before you pay. For the right group, this is a flexible and comfortable way to spend an afternoon on the Kona coast.
