Power boats from Brave Borderer

This Super8 cine film footage was taken by my father - the late Lt Cdr Brian Henry Millica - during the time (1966-1968) he was chief engineer on these boats.
Quality is not as good as some of his others - seems very grainy - possibly due to relatively low light at maximum zoom because it seems better when he zoomed out.
Very brief footage of the two Dark Class FPBs P1114 and P1115 but quality not so good.
Also some brief detail of Brave Borderer's helm and senior crew.
