Hi folks I don't know if this is good or bad ldea but. Going to post anyway I am attempting to build the tug boat Portgarth belng a newbi I asked what Skegness's was I know but everybody as to start somewhere deep diver put me right,my apologies for mistakeing him for someone else on a different forum sorry Fred.right back to my idea lt add got two cheeks witch you had to a shape so I decided to cut 1 inch dowling down the middle then cut it to fit the Skeg because I am led to belief that it is to displace water. Hope that it works. Regards Tom
