Hello, 
the cockpit of my Nelo racing kayak has broken off. I've attached some pictures. 

It needs to be quite strong as I pull myself up holding on to the broken part when getting out.

The appearance is not important.

What is the best way to fix this?

Thank you in advance, Jurgen

As said above, way too soon for exposure to water, especially this time of year.  Although initially hard within 24-48hours, epoxies remain hydroscopic throughout the main cure which can be 7 days or more depending on ambient temperature, post cure etc.

In your case, try and get the boat somewhere as warm as possible to see if it is still green enough to drive out the moisture with warmth.  You might be lucky and get rid the whiteness that way.  Otherwise you will need to sand away the bad resin and add fresh.

Also bear in mind that you can get similar issues with poorly mixed  resins too as it won't fully cure  and remain vulnerable to moisture, so it is key to keep close eye you measuring and mixing accuracy.
