Ray 680 — By Capt. Bill Pike — February 2001
|Part 2: Sea Ray 680 continued|
The 680 is built.
Both hull and deck are cored with Baltek AL600 balsa and laid up with
pricey, high-performance vinylester resin. All-glass, hat-section stringers
and transversals make the hull strong and resilient, and Baltek-cored
fiberglass ribs and ring bulkheads further strengthen the hull-deck construct,
once they’re joined with through-bolts and fiberglass. Moreover, the sound/vibration
attenuation package is all-encompassing, with isolation mounts under all
mechanicals and an engine room buttoned up with multilayered acoustical
bulkheads and overhead panels ranging in thickness from two to six inches.
Check out the dB-A readings I recorded during our sea trial: They’re low,
even at WOT.
