Could anyone tell me history of this sail number. Asking for a friend who’s keen to rejoin the class! 

Miles James built it himself to his own design.
 
Ive never seen it, so I cant comment on performance I believe Keith Callaghan has sailed it.
 

Some nice information here -

Hi Hamish, Miles built her as per the link above, and she was originally a light persons boat then he did some mods to the hull to make her carry more weight IIRC. I don't think she's been seriously sailed since so possibly unproven. If it's Mr B then it's in his neck of the woods, sure he could ask for a trial sail?! 

Another good woody to consider is the Let it Ride 3553 on Apolloduck for 3K

3376 and 3236 will be at Largo once lockdown ends I think, but open to suggestions!
