You might email Wes Vermeulen at West Bay and see if he knows of any potential sellers. Harber Lights was a nice looking 48, sold back in September, I think for $165K. I emailed Wes back in October, mentioned the ones that were on the market (including the 45 you looked at) and got this reply:
"Only thing on market are the 2 but I know of maybe one other that had rumblings of maybe selling but his ask would be higher than the other but also better shape.
Will keep you posted,
