hello and welcome.
As you know leaks are sometimes hard to find. I would start by re bedding the chrome trim along the sides. Or at least be sure all the screws are there and tight.
The other place is any rails or seat fasteners at your upper helm. This is more common than you might expect but it is also serious. I am not sure on your year but there is a core between the floor and the ceiling of your salon. If any of these fittings leak and water gets in, the core can dissolve and you are left with a pretty serious fix.
You know there is water somewhere and you need to get it stopped as soon as possible.
If the core becomes wet it will be like mush and you will notice your upper helm floor will get spongy when you walk on it.
Many feel re bedding the rail mountings is normal maintenance on these boats.
Sorry I can't be more specific.

I have noted the same issue on both boats I have owned, regular maintaince includes the reseating of the rails and deck fittings to avoid leaks

Thanks guys for your advice, I have tried in vane all the things you guys have said, my next option is remove the radar arch and check the base to see if it may have cracks there, not an option i relly want to do because it is quite a lot of work.

Does the leak show up during heavy rain, light rain ? Would it be possible to add some non staining food color to some water, try it around some likly areas to try to trace it ?

It only leaks at heavy rain and windy on either side this why I'm thinking it is coming in under the radar arch base, I'll know soon. I'm planning on removing the arch as soon as I can arrange a crane to remove it.
