Sea animals collide with motor boats occasionally but this Seaglider would be even more likely to do so because:

- It doesn't produce as much underwater noise as a motor which would normally serve to alarm sea animals.

- It goes a lot faster, giving sea animals less time to react.

Then there is the concern about what a collision would cause to the Seaglider itself if the hydrofoil broke off or worse, didn't break off and caused the Seaglider to plunge, nose first, into the ocean.

The other thing to be concerned about are sub-surface rocks. If a boat goes over a rock that's hidden just below the surface, it can badly damage the boat and motor and can cause death, but again, the faster you go, the more damage can be done.
