A small boat moves on the lake as if by magic. The secret lies in a special chain drive under the lake, which is magnetically connected to the boat. Complete kit with motor (for connection to 14 - 16 V AC voltage, 60 mA), drive chain, sea foil, sea paper and 2 rowing boats (1 for H0 and 1 for N / TT). The edges of the banks only have to be "camouflaged" with grass. Base area: approx. 260 x 180 mm, installation depth (including motor) 35 mm.
