Model perahu listrik ini terbuat dari polystyrene (gabus) dan lembaran plastik. Motor dc kecil di suplai dayanya oleh baterai 9 volt. Baling-baling kapal terbuat dari pelat bekas kaleng minuman. Poros baling-baling terbuat dari sedotan plastik. Untuk mencegah kebocoran air ke dalam perahu, poros baling-baling ditutupi dengan selubung (stuffing box). Stuffing box terbuat dari sedotan plastik.

Rata-rata kecepatan di jalur pertama segera setelah start adalah 40,8 centimeter per detik (1,5 kmh = 0,9 mph). Dengan baterai yang lebih bagus dan dengan motor dc berkinerja tinggi, kapal ini potensial untuk mencapai kecepatan maximum yang lebih tinggi.

Jadi jangan buang polystyrene, sedotan plastik, dan kaleng bekas minuman. Anda dapat membuat perahu yang indah dan kencang dengan sisa barang-barang rumah tangga tersebut.
