To be fair, how are these boats being used? Racing or cruising? What are the relative speeds. A modern boat has a WL as long as the length overall or nearly so - reserve buoyancy in the bow be dammed. Those that plane have to be super light.Whilst I prefer the build quality of some not so new boats would it be fair to say the new boats handle more dingy like so have that fun element ?
Some of these 42ft boats are claimed to be doing speeds in light winds faster than I could ever go !
If you don't have a penchant for freeze-dried food & the scintillating ambiance of plastic crockery, like to carry a modest wine selection around with you, tools to fix something if it breaks, a proper dinghy with an outboard, business-like ground tackle, perhaps with an all chain rode, some form of land transport and not to mention, supplies & gear for a nice, say, three month cruise, I doubt that you will find that relative speeds are at all that different and you are likely better off with a hull designed to carry that load in the first place.
Of two boats with the same sail area/displacement ratio, the heavier one will actually be faster in light airs; up to a relative speed of 0.7 certainly and up to 1.0 probably.
We've had these discussions before. The fact that you can sleep in the back of your zippy Audi station wagon does not make it an RV, to use the much-loved automotive comparative.
A fortnight holiday charter in the Med is a completely different thing from a two month expedition to the Shetlands. For the latter give me a solid sea boat that will look after me when I'm down or just being stupid, a bow that keeps most of the water off the deck and a roof over my head so that my hands don't go all numb and shrivelly.
