I have been building a freelance tug,based on the looks of the New Castle RTR model ,but this is bigger I have used a fibre glass hull from thr Holmsider ,and raise the bulwarks forward, fitted a 4" kort and 5 bladed prop, the superstructure and decks are from 1/16th and 1/8th ply, she is nearly finished and almost ready to get wet, I will post more pics later. geo
