Thanks for all the site to look at my wife hates you all now
The thing is I want one for both the broads and sea use.
You had asked about fuel economy i.e. what you could currently get out of your boat, pottering around, against the consumption of a big V8 doing the same. Therefore, I have to add, in as much a I love the Sea Ray models especially the Sundancer, Sealine built their boats with an economical diesel engine. The interiors are similar although my preference would be the Sea Ray, but there's very little in it but, what would win for the Sealine 23/24/25 would be the useability and then the re sale value.
The Sealine 23/24/25 are the same boat but different production years.
If you are ok with a boat on the broads with a petrol engine, go for it. They are smoother, quieter and generally easier to fix.
