Boats are not cars. Changes in lubricants for cars are made allowing for increasing motorway use, higher engine temperatures, long periods at high speeds, increasing power outputs. In consequence there is increasing emphasis on boundary lubrication, oxidation resistance, viscosity improvers, anti-foaming, etc., etc.

In contrast, yacht engines are used in a totally different way that for many has not changed for decades. Run engine briefly to leave berth, turn off, go sailing. Reverse process when returning. Maybe a bit of battery charging and running at about half to two-thirds maximum revs to get back to berth when the wind drops. The additives and suchlike in car lubricants are not needed and may well be harmful in these circumstances.
 
I bought tractor oil at our local farm store. Good price too for 20 litres. My Perkins engine is basically a tractor engine with bits stuck on for boats. I think it is CD or the slightly later CF.
 
I haven't been able to find CD anywhere but Tesco and ASDA (and probably other supermarkets) do CF or CF-4 and any motor factor or agricultural merchant is likely to have similar. No need to go ebay and pay postage unless you are very isolated!
Halfrauds seem to have CC or mono 30 for vintage cars then jump to much higher spec stuff and all expensive, no luck there.
 
Don't drive yourself mad, as has been said any 15/40 mineral oil will be great. Much better to have new, very slightly different spec oil than black treacle or none at all :)

The OP asked for an explanation. The reference provides exactly that. I suggested Halfords basic Diesel engine oil, not the fancy stuff.
 
I had a shufty at the oils in Kip Marina chandlery today. There were two Yanmar branded oils for diesels: one was mineral to CF-4 at £32 the gallon and one was semi-synthetic.
 
The VP manual and Vyv Cox web site both recommend CD oil for these engines if you can find it. The OP has shown where you are able to get it from at a reasonable price. I also asked the same question about Exol Victory some time ago, but did not hear from anyone using it. The answer to the OP would seem to be yes, it is the correct oil for the 2000 series. There seems to be no other UK source of CD?
Whether or not other grades would suffice is academic if the preferred one is available at a reasonable cost.
