    Default Dimple repair

    Prior to my ownership one of the previous owners had taken the time to place (neatly laid out and drilled) dimples into the bottom of my boat. I would like to fill these dimples in and am looking for suggestions on what to use.

    The dimples are about the size of a button top "type" screw head and approximately 1/8" in depth.

    My thought was Sea Bourne epoxy followed up with a flat sand....

    Please note, there is no glass exposed in any of the holes and no issues with the hull.... I just see no benefits from having the dimples there, and in fact think the hull may perform better without them.

    Any input would be helpful

    Thanks

    surface modification or texturing often aids in friction or drag reduction (golf balls, shark skin), make sure the dimples are not factory prior to filling.

    I am in agreement. RPB seem to have a handle on this.

    Even if it isn't factory you are probably better off with the dimples. Just my opinion.

    If you fill the dimples in and make the bottom smooth you will lose top end speed.

    If you simply want to fill the holes, I'd use 3m marine filler, sand down and paint or gel coat over to seal it up. It'd be alot of work... but you can do it. Gel would work best on the bottom, as it takes lots of abuse (bunks on trailer etc).

    As people have said, it won't hurt leaving alone....may even hurt your top end speed to fill em up.

    Good luck,

    Ken
