Hi guys,
just wondering if i could get some advice on how to repair the deck on my sailing dinghy! The picture shows the area of de-lamination (the green rectangle) , the only stress that this section goes through is when I stand on it whilst sailing, however the top skin has come away from the foam core, and I have a feeling the bottom skin has split along the underside of the 'v', so as you can imagine, as you put weight on the section, it deflects around 1-2cm, and makes crunching noises as the foam deforms.
I have had a quick attempt at repairing this by drilling a series of holes, and injecting resin so that it saturates the foam, however this still hasnt worked, and the section still deflects when pressure is applied!
My current plans are: wet lay-up a ~20 x 120cm piece of heavy biax weave along the centerline and hope for the best, but i am now doubting myself as the top skin of the sandwich is not fully attached to the foam, sadly i do not have access to the underside so cant strengthen there! The direction of fibres is shown by the red lines (45-deg from top to bottom in picture)
I want to spend the least amount of work time (curing time is irrelevant) because i want to get sailing! so chopping out the section and replacing is a route i dont really want to take!
any help would be muchly appriciated!
- Henry

You could cut a hole in the side of the boat hull instead and repair the crack on the underside of deck keyhole style.
Then just glue set the repair hole back in place and carry on until you do a better fix later?
