I have for sale my model fishing boat which was scratch built from a model boat magazine plan, forgot who designed it though. it is built from balsa for the hull sides covered in a pair of the bosses tights before sealing and painting.The stern and deck are ply then painted to seal. all the deck and cabin fittings are scratch built from photos found on line.
it is quite heavy about 10Lb of lead if I remember correctly, the length is 30" by 16" to keel bottom and beam 9", fitted with a 12v to 14V motor, 70 mm prop. Batteries and 320 amp fan cooled speed controller included, currently running off 12v 6 amp batteries.
space needed for new project £150 or reasonable offers collection from Lincoln would be advisable due to size and weight. But could arrange delivery if required.
