Yes the meaning and purpose of much of life is an enduring mystery. Jigsaw puzzles just deepen the conundrum.
As to the 1/4 toners of today(do such critters exist now they don't use IOR anymore?) they are just big skiffs. Even those Sydney 38's look very wet and uncomfortable ( I guess they would be 3/4 tonners in the old language). I sailed out to watch the start of the Gosford to Lord Howe race last year and most of the competitors looked liked stretched versions of an 18 footer. It was only blowing 15 knots and the crews on these boats already were in full waterproofs. Looks pretty easy to be swept out the slippery dip stern too, but it must be fun when they surf waves at sea and plane. Wet and wild - a bit like when I used to race around the harbour on my moth.
I used to love racing 1/4 tonners with the CYC in the 70s. It was close and exciting racing, but you could not say it was fast...Though at times we thought it was...
PS In the USA they have put the Dana 24 back into production, see
