Haven't found a plan - yet 🤔
I take it you mean the Scimitar class FPB, Fast Patrol Boat.
At 52' 6" a 1:72 model would work out at 8.75" !!
Not impossible but not easy 😉
For 17" LoA you're looking at ~ 1:37.
Soon as (if🙄) I find a plan you'll be the first to know (along with anyone else Online😁).
Maybe Halmatic can help you?
Cheers, Doug 😎
