Nope no issues yet, well...leaking portlights and deadlights, which I will be rebedding with butyl and Dow Corning 795.
As for the chainplates I like the design. If I am not mistaken this is what Catalina has done as well. Very visible and the end is securely fastened to the hull via an encased fiberglass tab. See
Note the leaking deadlight:
had this chainplate been fastened to a wooden bulkhead I believe the strength would have been compromised.
Which Precision 27 are you looking at? Is it online?
