Many suppliers of U bolts of that type - just google it. Seasure, Wichard, 3is are just a few.

However that is almost certainly an obsolete type as most are now metric both in spacing and bar size, so if you want a direct replacement you will have to get it made. Typical price of a standard U bolt of that size in 316 stainless is in the range of £10-15 and a custom made one around £30-40. Prices based on my recent experience of buying such a thing - fortunately I was able to use a standard one!
 
The problem with most of the standard U bolts is that they are much narrower centres of the legs than most of the older (and probably custom made) items such as the OP has.

At a guess that looks like 3/8" legs at 2" centres and most 10mm legs are at 30-40mm centres.

They are at 2.5" centres

Definitely custom made then. You will need to go up to M12 and then the centres will likely be 70mm.

Would make sense to have the legs metric with metric thread but you may have to enlarge the holes in the deck a bit.

I've been to see a man who says he can make new ones. They are M8 (or 3/8)

Personally I would avoid having the deck-plate welded to the Vee because the characteristics of the Stainless steel are easily affected by the heat of welding - if not properly done. I would prefer something like this:

Whatever your choice, your best bet re safety is to go for a manufacturer with a good reputation, even if more expensive, like Wichard.

p.s. check whether the 'U' or 'V' part is straight or whether it is angled. Sometimes they have a 5o angle to be more in line with the shrouds.

Agree about not welding the plate. I like the Seasure one that I used as it has a separate plate and a nut with a rubber cover above it.

V part is angled - I have specified 8 degrees. Going to get it welded because the original was . . . all the working has been around the stud where it goes through the deck and the backing plate, the welds are fine.

Going with 'a manufacturer with a good reputation' h m m m . . . the local metal shop I am using has an excellent reputation.

That's OK. :)

Whatever I can do, I do myself, especially machining and fabrication. However, when welding of stainless steel or aluminium is involved I go to the engineering works of an old friend (have known each other for around forty years) who has some employees who are real experts. The only 'problem' I have is that he always refuses payment; that's when a bottle of single malt come in handy when later I pop in to say hello because I 'happen to be in the vicinity'. ;)

Bottles of single malt are my favourite currency :D
