Sena Cruise

Sixteen cabins, and the two grades you can actually choose between are $24 apart. Of the eighty-one boats we hold more than one double rate for, only four put less distance between cheapest and dearest room. The middle boat on that list charges half again as much for its best double. Sena charges eight per cent more.

Sixteen is corroborated and three guests reach it independently: a Korean review from May 2020 that counted sixteen rooms and called the vessel newly launched, which props up our single-source 2019 launch year; an Italian in February 2023; a German in September 2025. One disagrees: a five-star German in December 2025 puts it at twenty-four rooms and about fifty people. Everything else at ship level is thinner: steel hull and Lan Ha on one source each, nothing for capacity, decks, length or the pier. Keep sixteen in proportion: 133 of the 142 ships we track publish a cabin count, the median is twenty-one, forty-eight are at sixteen or fewer. How many people on board has more.

A spa, kayaking and balconies are verified, and both published grades name a balcony, better support than most boats give the tick. The gym rests on one source. A pool and a jacuzzi are mentioned by nobody we read, which means nobody publishes them rather than that there are none aboard.

What the $24 buys, and it is not floor area

Balcony Deluxe and Balcony Executive carry identical published specs: 25 m², a double or twin bed, a sea view, a balcony, every field of it on a single source. The one recorded difference is the deck: six Balcony Deluxe on the first, eight Balcony Executive on the second, fourteen of the sixteen. The other two are Terrace Suite Balconies, sleeping three, with nothing in the record. So the $24 buys a flight of stairs. The French guest writing in May 2026, critical of most of the trip, singled out the second-deck cabins as better kept.

The cabin size printed for this boat is 25 m², and you will meet it ranked below a bay median of 34. It is the winning side of a draw rather than a measurement: three sources say 25, three say 40, one says 50. It holds for the fourteen rooms whose grades also say 25, and says nothing about the two Terrace Suites. What your cabin gets you is the page on that.

Three grades, read on 6 August 2026, quoted by the room rather than the head, for the single night: Balcony Deluxe $286 for two, Balcony Executive $310 for two, Terrace Suite Balcony $525 for three. Each caps what you should be asked.

The per-person figure listings advertise, $143, was swept on 7 August 2026 and nothing corroborates it; the widest we have seen it quoted is $308. A guest in October 2025 found ten per cent of tax added to the drinks at settlement, not printed on the menu. What is not included has the rest.

The evening is a group evening

Karaoke appears in ten of the 148 reviews, dated 2022 to 2026. Five of those ten are five-star reviews, two are four, two are three, one is a single star, and none of them is a two. Three five-star guests credit the guide Kent for making the singing fun. A guest in October 2025 records that nobody on their sailing wanted to sing. A guest in June 2025 was told before booking that this was not a party boat, then spent the evening under loud singing from a drunk group and watched a light fitting come out of the ceiling.

The complaint and the praise are about the same feature. Six reviews between 2022 and 2026 put dinner on the partially covered top deck, and a four-star adds an indoor dining room and a covered outdoor dining area, so there is other seating. The June 2025 guest’s point is that the noise took the whole boat, top deck and balcony. Ask what is scheduled after dinner; what to expect on board has the usual shape.

Which bay you are actually in

The record says Lan Ha. The guests disagree, and the weight leans one way. Five reviews between 2023 and 2026 describe sharing the water, reporting twenty ships in the overnight anchorage, dozens at one stop with overtourism blamed for the dirty sea, ten to twenty at every stop, a hull parked mid-Ha Long apart from one quick Lan Ha cave, and a July 2026 sailing never far from a dozen ships. Three say the opposite, among them the 2020 Korean guest and a French five-star in April 2025 who found Lan Ha calmer, though the Korean guest still finished by recommending a different bay to a first-timer. The quietest bay puts numbers on all three.

Where it costs you

We read all 148 reviews: 114 five stars, sixteen four, six three, five two, seven one. Twelve at one or two stars is 8.11 per cent, and three of those carry no complaint, putting the substantive low tail at nine, or 6.08 per cent. The listing’s average rests on a review total smaller than our own count, so we drop it and use the distribution.

The boat’s condition divides that file. Sixteen reviews between 2022 and 2026 call the cabins or the boat clean. Five push back between 2023 and 2026: a dated exterior, rooms not very clean, a boat called vétuste with a dirty broken minibar, a hull older-looking than its online pictures, dirty sheets and a flooded bathroom. Four of those five are 2025 or later, another reason to pay the $24.

Pace is next, in four of the 148. A September 2025 guest says the schedule is packed with almost no downtime, kayaking is called at eight, and lunch on day two was at a quarter to eleven because the boat’s permit expires at noon. The French guest was woken at six and left at eleven; a March 2026 guest was off by half past ten. The programme says half past eleven. Plan it shorter.

Two guests, in September 2025 and January 2026, say the extra day happens elsewhere: one onto another company’s day boat pooled with other ships’ guests, the other looping the same water. Weigh two days or three against that fare. Six reviews between 2022 and 2025 report rubbish or an oil slick in the water, which no operator here controls; kayaking has the rest.

Two 2022 reviews describe the booking rather than the boat, and we cannot test either: one guest says they were put on a lower-class hull and charged in full, another that an offer was withdrawn a day later. A guest in December 2025 says their young son fell through a high chair that gave way and hit his head, and that the manager blamed an unfastened buckle. One family, one afternoon, and we cannot check it. Anyone travelling with a small child should read the low reviews, and we sort the grievances that recur on every boat here from the one-off ones in what guests complain about.

Against all that, eighty-seven of the 148 mention the crew, almost all favourably, Mike named in four and Kent in three. Cat Ba Island comes up four times, one guest calling it the best part of the trip; Cat Ba and Ha Long City says what is on it.

Who it suits

Two people or a small party who want sixteen cabins rather than forty, who will pay the $24 for the upper deck, and who would rather join the evening than hide from it. Six of the eighty-one rate sheets we hold have a top double at or under $310, Sena’s exactly on $310 next to Renea’s. Hence its line on the small boats, under best value, and among the Lan Ha boats on this water.

Who should look elsewhere

Anyone who wants the second night to take them somewhere new. Anyone booking for quiet water should read those five reviews against the three quiet ones. And nobody publishes the pier, so if you drive yourself, get it named in writing before you read which harbour you leave from.
