Single-engine floatplane

Name not confirmed

What the community calls it

Widely identified as the Mammoth Streamer216.

GTABase files a GTA 6 floatplane as the Mammoth Streamer216 on a de Havilland Canada DHC-6 Twin Otter. The Twin Otter is a twin-engine aircraft, and the aeroplane in our frames has one engine, in the nose. Either their donor is wrong or their name belongs to a different aircraft than the one we are looking at, and we cannot tell which from here.

What supports it

  • High wing, two full-length floats on strut cages and a conventional single fin: a bush floatplane, which is the category their entry sits in.
  • The cabin door aft of the wing strut and the boarding ladder up the right-hand float match a passenger-carrying float operation.

What does not

  • Their donor, the DHC-6 Twin Otter, has an engine on each wing. Ours has one engine in the nose and a cowling ring around it.
  • No registration or name is legible on any of our four frames of this aircraft.
  • Two of those four frames show a blue and white livery and two a white and yellow one. We have been treating them as one type; nothing proves that either.

Read on GTABase, September 17, 2026. They name the vehicle but no picture, so they confirm that it exists and not that it is the one in our frame. The identification is theirs, not ours.

We have not confirmed this. Our confidence in the identification: low.

When the real name is confirmed, this page moves to that name and this address keeps working.

A single-engine floatplane banking over turquoise shallows, close enough to count the struts, held here with two more press stills at a marina dock and two trailer flypasts of the same type.

The aircraft is banking left over clear water with a wooded shoreline across the top of the frame, shot from above and behind. It is a high-wing monoplane: the wing sits on top of the fuselage, white with a yellow band and a pair of thin black pinstripes near each tip. There is one engine, in the nose, with a polished cowling ring around a yellow cowl, and the propeller is turning hard enough to blur into a disc.

Two full-length floats hang under the fuselage on cages of struts, with a boarding ladder running up from the right-hand float to the cabin door. The tail is conventional: one fin with a yellow top, a horizontal stabiliser either side. The cabin has square side windows and a door aft of the wing strut. Something dark is painted along the outside of the right-hand float and does not resolve.

Two more press stills show a blue and white aircraft of the same layout at a marina dock. In the wider one, moored at the stilt houses with people on the jetty, the operator's name reads on the nose in blue script, Brian's, and it is the name on <a href="/gta6/locations/brian-s-boat-works-marina/">Brian's Boat Works & Marina</a>'s own sign; the smaller line beneath it and the registration on the fin sit under this site's floor for lettering and are not read here. The close-up shows the tail of that script, a possessive s, and the end of a word, rina, at a size that leaves no doubt, with a pilot in the seat and a figure at the door.

The fourth sighting is from Trailer 1, over the same kind of water, with the yellow wing bands showing from above. The fifth, from Trailer 2 at 2:21.83, passes low and backlit: a high wing, a radial engine in a round cowling with the hub visible, twin floats on cross-braced struts, and a run of registration-style capitals on the underside of the wing that does not resolve in the motion blur. We are treating all five as one type. Nothing proves that, and two liveries are in play: white and yellow in the air, white and blue at the dock.

A community database names a GTA 6 floatplane the Mammoth Streamer216 on a Twin Otter, a twin-engined aircraft; ours has one engine in the nose, so either their donor or their aircraft is not this one, and the hypothesis block says so. GTA 5's floatplane was the Dodo, a single-engine high-wing on twin floats, and that is the counterpart in shape.

How to recognise it

  • High wing, white with a yellow band and black pinstripes near the tips
  • One engine in the nose, yellow cowl inside a polished ring
  • Two full-length floats on strut cages, ladder up to the cabin door
  • Single fin with a yellow top, conventional tailplane
  • Square cabin windows, door aft of the wing strut
  • Brian's in blue script on the nose of the dock aircraft

The frame it comes from

The frame is a still from the official Press pack, which carries no timecode. It is 3840 by 2160, and the vehicle occupies 1267 by 777 of it. Also in it: the Leonida Keys.

These figures come from the dataset, not from the prose above. We measure everything and claim what counts. How we work

What we still do not know

  • The lettering. There is a registration-style run on the wing in the Trailer 2 flypast and a marking on the float in the press shot. Neither resolves at full resolution, so we do not know whether the two carry the same registration, which is what would prove these are one aircraft rather than one model.
  • Whether it is an amphibian. We can see floats; we cannot see whether wheels retract into them.
  • Whether the blue and white aircraft at the dock is the same type as the yellow one in the air
  • The registration on the fin of the dock aircraft, under the floor at this size
  • Everything measured: top speed, capacity, price, where it spawns
