Re: Catalina 27 or Pearson 28 or Ericson 32
I don't know much about each sailboat's characteristics but I find the Ericson 32 to have nice lines. And they have good reputation in terms of construction too.
Diesel is definitely a piece of mind. When you replace a fuel filter and under-tighten the hoses by mistake and fuel starts leaking into the bilge, you'll feel better knowing it's diesel.
