Seaisee — a spacious Indonesian yacht built around diving

Seaisee suits divers who want the Indonesian route without giving up room to spread out between dives. The yacht offers a large outdoor deck, shaded dive areas and several cabin layouts, so the trip can work for solo travellers, couples and families. The reason to choose it is the combination: a spacious platform for a full week of diving, three speedboats to handle the water work, and a liveaboard setup that also welcomes snorkellers and non-divers. Nitrox, technical diving, rebreathers and sidemount are part of the operation rather than an afterthought. Step aboard for Banda Sea diving, but expect the boat itself to shape the trip as much as the route.

Seaisee makes the impression of a purpose-built luxury yacht rather than a compact dive boat. The open deck gives divers room to move after boarding and between dives, while the upper-deck cabins keep accommodation above the busiest working areas. Its 2019 renovation matters here: the boat combines the character of a vessel already used at sea with facilities designed for longer stays, including air-conditioned lounges, outdoor dining and a dedicated observation area. Movement around the boat is straightforward, with the dive platform kept separate from the living spaces. Three speedboats handle transfers to and from the sites, so the main yacht can remain a comfortable base while the dive operation moves independently.

Seaisee carries a close crew-to-passenger ratio, with local and international crew members speaking English, Chinese and Indonesian. That language mix is useful on a boat where the dive briefings, meal service and transfers all happen in a shared space. The crew's role is most visible in the working transitions: getting divers to the tenders, keeping the dive area moving and resetting the boat for the next return. Evenings can move from outdoor dining to the bar, a barbecue or quieter time in the lounge. The boat is large enough to offer separate corners, but not so large that the people running the week disappear from view.

The recorded route is the Banda Sea, running from Ambon back to Ambon. Trips last six or seven nights, with departures listed as either seven days and six nights or eight days and seven nights. No individual dive-site descriptions are attached to this itinerary here, so there are no verified site names, depths or site-specific features to add. The route is therefore the clear starting point: choose the departure length first, then confirm the exact site plan for that sailing.

The crew speaks English, Chinese and Indonesian, and the vessel carries oxygen, first-aid kits and crew trained in first aid. Courses and private guiding can be arranged as optional services, while the diving operation also supports technical, rebreather and sidemount divers. The available information does not give a guide-to-diver ratio, the qualifications held by individual instructors, a minimum logged-dive requirement or a specific recall system. Those details matter more on a current-heavy Indonesian itinerary than a generic promise of guidance, so they should be checked against the chosen departure before booking.

The dive deck is built for more than standard recreational diving. It has a shaded working area, a dedicated platform, rinse tanks and separate rinsing for cameras, with support for technical diving, rebreathers and sidemount configurations. Three speedboat tenders carry divers to the sites and collect them after the dive, keeping transfers away from the main yacht. Nitrox is available for certified divers as an extra, and rental equipment is offered separately. Oxygen and first-aid kits are carried on board. The setup is strongest for divers who bring specialised equipment or cameras and need a proper place to prepare, rinse and store it; tank volume, tank material, filling system and compressor details are not stated here.

Between dives, Seaisee gives the trip more than a place to sit and wait. Divers can choose shade on the dedicated outdoor areas, the observation deck, the air-conditioned interior lounge or the jacuzzi, while the large deck leaves room for cameras, towels and people who simply want quiet. Stand-up paddleboarding and fishing are available when the boat is settled, and beach barbecues can take the group ashore. The separate camera-rinse area is useful for photographers who do not want wet equipment mixed into the general dive routine. Wi-Fi, a library, audio-video entertainment and laundry service cover the practical gaps without making the boat feel like a resort catalogue.

A fixed onboard timetable is not given, so the exact sequence of dives and meals should not be assumed. The boat's setup is designed for a repeated dive rhythm: divers prepare in the shaded dive area, transfer by speedboat to the site, return to the main yacht and use the rinse facilities before eating or settling into the lounge. The large deck, jacuzzi, observation area and outdoor dining space fill the gaps between water time, while fishing and stand-up paddleboarding offer alternatives when the schedule allows. On a Banda Sea trip, the boat's movement between Ambon and the dive areas becomes part of the day, but the number and timing of dives depend on the selected itinerary.

Food is one of Seaisee's stronger points, with both local and Western cooking, vegetarian and vegan options, snacks throughout the day and meals served as part of full board. Outdoor dining and beach barbecue add variety when the route allows it. That matters on a liveaboard where meals have to work around several dives: a plate arrives when divers can actually eat, not as a formal interruption to the day. The galley combines Indonesian dishes with more familiar Western choices, giving a mixed group room to eat well without turning every meal into a negotiation. Tea, coffee and non-alcoholic drinks are included, and the bar gives the evening somewhere to gather after the last dive.

The cabins are air-conditioned and have private bathrooms, with categories ranging from single and triple cabins to twin and double master cabins. Sea-view options add a more open feel, and selected cabins have accessible balconies; one sea-view category includes a private jacuzzi. Panoramic windows bring daylight into the upper-deck accommodation, while the interior lounge provides an enclosed place to cool down. The practical advantage is choice: a solo diver does not have to book around a couple's layout, and groups can look at family or triple arrangements. Outside the cabin, the boat offers a jacuzzi, bar, library and observation deck rather than forcing every quiet hour into one indoor salon.

The itineraries depart from and return to Ambon. Airport and hotel transfers are included, covering the journey to the boat from those starting points. Arriving in Ambon the night before is the sensible choice, leaving room for flight delays before embarkation and keeping the first day focused on boarding rather than a rushed connection.
