I have just looked at a 45 foot boat built in 1979 and described as being a solid glass hull.
When I rub my hand over the hull there are some very noticeable ripples 3/16ths to 1/4 inch deep over 3 to 6 inches just under the turn of the bilge. I think they are both front to rear and top to bottom
I can not believe the boat came out of the mould like this.
Before I go to the expense of a survey does anyone know what this might be and how serious it is.
I do like the boat but I suspect something serious could be wrong.
