Stan, they must have some great "wacky tobaccy" in your area. You're joking, right?
The similarities between Westbay and Bayliner end with both being boats and both floating. There are more differences between these two manufacturers than similarities.
GFC, I think you are comparing the Westbay Sonship zillion dollar late model yachts with the Westbay boats that were built in the late 1980's.
They are clearly, from the photos of the one boat that is for sale in the PACNW, not in the same category. What Westbay became, and what they were are only similar in name.
In looking at the photos of the 45' westbay, it is the almost exact same interior layout as the Bayliner 45/47 series. I'm suspecting that the Westbay was built to compete with the Bayliners that were very popular, and built "just down the road" in Arlington Washington
I'm not going to knock the Westbay but to my eye the jointery, and the rest of the interior is about par with the Bayliners of that era. Nice but certainly not of the quality of say the Grand Banks boats of the same vintage. Truth be known I prefer the Teak of the older Bayliners over the Oak that it appears the Westbay was built out of.
Westbay isn't the only one that seemed to try to compete with the Bayliner Pilothouse models so popular in the PACNW. Delta (a name known for their fishing boats) also produced a few pilot house boats. They as well look nice, but in the end they did not sell as well as the Bayliners and were short lived models in terms of production years. To me, and I am much better familiar with the Delta "copies", they were nice, but somewhat lacking in engineering refinement. I think the intention was there but there just wern't the dollars spent on engineering, that the Bayliners had the benefit of.
It appears that Westbay later made a name for themselves in the giant yacht market, and that is fantastic, but again, that came later in time than the model the OP is looking at.
