I power washed my boats yesterday. sitting around outside all winter and they grew some green foliage. In spraying off the hulls with mega pressure I determined that:
- there is alot of friction on scratches in the hull. A L O T !!!
- composite scratches are WAY less friction creaters thsan roto.
- roto scratches with burrs still attached are the worse…d’uh.
- the visual is GREAT.
I have a Tsunami 140 I use for heavy duty rock gardening on rough basalt rocks and whew…I promptly got out a razor knife and trimmed off all the burrs. I have a number of composite boats that were used for basically the same terrain and the little and BIG scratches created very little friction.
