This is a dutch fishingboat.
With a ship like this,they catch all kind of fish.
The yellow ,,arms" can turn outside to drag nets behind the ship.
Chains and weights keep one site of the nets on the bottom of the sea.
Floating buoys keep the nets open on the other site,so the fish can go in the nets.
This model still doesnt have nets,because we still cant find any who fits.
wauw, my friend is playing with miniature boats too, he let them on battery driving on water and if you film that it looks like a real big boat... I love to see him playing with that :-)
