Products You Never Knew Existed

[Lamplighter]

Obviously, we do like it...

The link you posted for the video of assembly of the Greenland model shows the main problem
... it is somewhat complicated and time-consuming.
Ours is sort of heavy and awkward, and it's easier for 2 people to share the carrying of the two bags.

Cross winds are the biggest issue in actual use.
The newer models have rudders (optional ?), but not ours.
Otherwise, we feel the wide bottom makes it a very safe craft.

But we still never allow a kid to take it out without an adult,
It has never been overturned in the water, even during the few battles of "water-warfare".
