Re: Aluminum hull
Im recognize those "dents."
I'd put money on that being a Spectrum or Fisher welded hull.
Mine was totally rippled, worse than that, in about 5 years.
Never hit anything but waves with it.
The little ridges are from the internal support structure.
And yes, the hull is made from some mighty thin sheets of aluminum.
I figured a hull should not ripple from hitting water.
The rippling, and the poor turning of that hull, are the major reasons I sold it.
That and the fact that I could own 3 use specific boats for what I had tied up in that one.
