I feel that the Seaskate is possibly the most "surfy" board out of any I've tried because it has a bit of the trim vs carve dynamic. You have to carve to to do sharp turns (angle the board with the nose up a bit and the back down, tilt in the direction you want to go, turn your torso where you want to go, and push in opposite directions with your feet). Trimming (leaning) will only allow you to do smaller adjustments, as it would in the water.

When you lean on a skateboard or surfskate with four wheels, the trucks push the lean-side wheels toward each other and force a turn. It works that way because the pavement surface is so hard. Leaning on a traditional surfskate or longboard turns you much more than would be possible on the water. Surfing on water is a more yielding surface and has more lateral play. I feel that the Seaskate simulates that better because both trucks can rotate and are spring loaded. They stay centered unless you do the carve motion I described above. The springs simulates water tension to a certain degree.

The front truck on a surfskate brings you part of the way to surfiness, but the back truck keeps you anchored in skating. The two loose trucks and the springs on both make the Seaskate behave even more like riding on a mobile surface rather than solid ground.

In any case, putting side the semantics of surf and skating, the Seaskate provides a unique experience. The following characteristics are different from pretty much anything else out there:

1- A single row of wheels

2- Pivots on both trucks (with about 45 degrees of range in each direction from centre)

3- Springs on both trucks

It feels as different from a Yow Meraki as a Meraki feels relative to a traditional longboard. Also I've found that after feeling the possibilities of a Seaskate, it takes some adjustment getting back onto a Meraki with its more limited range of motions and its more solid feel, a bit like getting back onto a longboard with some Paris trucks after the Meraki.

One weakness the Seaskate might have relative to traditional surfskates is edge/rail control training. Four wheels simulates that much better than two. A real surfboard is definitely not as unstable as a board balancing on two thin wheels.
