After several days of rotating testing and exchanging opinions, as well as dismantling and analyzing the skeleton and skin of the Pengyi Yu ship after testing in the wave zone, the following conclusions have been drawn:
1. The skin of the boat is sturdy enough, and there are almost no visible scars on the bottom of the boat after intense friction with the beach;

2. The boat handles well in the wave area below 1.5 meters, and there is no significant difference compared to the hard boat;

3. The skeleton undergoes slight deformation under beach impact, so it is recommended not to directly impact hard ground as much as possible, including beaches, reefs, embankments, etc...

     In summary, it is recommended that the optimal range for the folding kayak of Pengyi Yu boat is within 1 meter of the wave zone. When approaching a beach with large waves, it is advisable to actively disembark and land to avoid direct impact on the beach...
