A couple of punch holes in hull from bad trailer load.

Hi picked up a used hobie that has a couple of punches from the cap nut where it was incorrectly loaded onto the trailer.


I've repaired fiberglass before but wanted to know if anyone had any suggestions. Current plan is to sand out the holes with a margin and then patch with laminating layers of glassmat and cloth fiberglass. I've done similar repairs and they've come out well.

Any feedback here? (pics). The holes are small and I've considered just filling them and spraying on some gelcoat but probably should do it right...

thank you,

Fixed your links. You had the page... not the image URL

Check the image below. Right click on the image to see the copy image address popup option:

Image URL ends in .jpg or .png or similar.

Navigate to your image page. Right-click the image. This must be an image address (url) rather than a url to a page. Click the above image to test and look at options to copy the address (url).

Rather than a link to the page it was on. The address should end in something like .jpg or .gif

Use the buttons above the post text area to find the proper code.

Use [img]then%20the%20image%20url%20and%20click[/img] again.

Be sure to have the option " Disable BBCode " unclicked!

and you are done.

Some quick updates post repair.

Sanded out the punches till I found solid glass and then tapered off on each side to allow for repair material and good material for the repair to grab onto.

Used marine expoxy resin and 1 layer of glass mat and 3 layers of cloth topped off with some white gelcoat (which I did not color match).

Repair is solid and just needs a knock down sand and final sand of the gelcoat and then some wax. The green hue is from the PVA which I have since washed off.

I used epoxy resin due to no or little shrinkage during cure. It's been getting cooler here and it works at a lower temp than vinyl ester. It is also structural and makes the repair stronger. I probably overdid it but it's fixed now and stronger than it was new :)
