is installed outside the cured
boat. This process does not require gel coat, no painting, no grinding,
repairing, and re-grinding, and no
grinding dust and water pollution during grinding are generated. Synthetic
fiber cloth is easy to dye and
has bright colors. It can also print pattern trademarks, and computer
embroidery trademarks and fonts.
The cockpit on the hull is made of waterproof fiber cloth sewn into the
cockpit cover, which is low cost,
light weight, small in size, easy to transport and store; a balance board is
set behind the cockpit, and the
balance board is higher than the set distance from the water surface. This
setting does not affect the
normal operation. The rowing speed, because the setting is in the air, when
the boat body is inclined to
the set angle, the end face of the balance plate is immersed in the water to
generate a reverse force, so
that the boat body is restored to balance. Because of the balance device, the
boat body can be made
narrower. thereby increasing the speed.
