As far as I’m aware, unfortunately the RNLI turned most of them into bags, keychains etc...
If you are willing to consider new, Crewsaver currently have two hybrid offerings:
The “Evolution 250” 60N Foam + 190N Inflatable
https://crewsaver.com/uk/9326/commer.../Evolution250N
This is probably the equivalent of the Baltic above. I really like them, it’s well cut and comfortable. Costs around £250
The “Inshore 380” 90N foam + 290N Inflatable
https://crewsaver.com/uk/9326/commer...55/Inshore380N
This replaced the original design hybrid ones (like in your photo). You can buy one, but you have to get it special order. Not cheap though... around £550 last time I checked!
