Love Inflatables ISS  seriesos the best packrafts for improved speed because of the longer waterline and streamlined shape.

We have been devoted in improving the model  for a long time.

The narrower hull not only reduces water resistance, but also lets you paddle the packraft with less effort.

We also use detachable fins to reduce water resistance and increase the overall stability and tracking. This also improves the speed of the  ISS  series

Although it  has a narrow hull, it is specially equipped with a high seat cushion to avoid paddlers getting squeezed in between the tubes. Eventhough the inner width of the raft is narrow, you still have plenty of space on top of the high cushion seat.
