Spider cracks in gel coat below waterline, fix or leave?

[CaptainBeachBoy]

While swimming the other day I noticed some ‘spider cracks’ on the transom of my Ribcraft 5.85 below the waterline. The hull is 2017.

They don’t seem to be very deep but as they are below the waterline do they need fixing or can they be left? I don’t want water getting into the fibreglass over time. I’m happy to get them fixed but the grp repairers I’ve emailed don’t seem to be interested in such a small job.

I will attach a photo but I appreciate it’s not amazing as it’s from my go pro under the water! Any advice would be amazing.

Thanks

Stress cracks my guess if through to the resin it will cause problems in time as resin isn’t waterproof

A job for Captain Tolley's perhaps?

The cracks look pretty narrow. If you are going to pay to fix it, why not just wait? If it bubbles it is still pretty much the same job. Grind, gel coat, sand, polish. If the boat is stored in the water often that is a different scenario.

The boat lives on water for most of summer, usually 3 weeks on water for every 1 week in dry stack roughly?

I’ll look into this, thanks

Maybe worth getting the manufacturer to take a look ? 2017 hull may well have not gone in the water till 2018 so may well be under 5 years service ,many of the new boats have 6 year warrantys and more
Surely worth a try ?
