Scope vs catenary (Rocna Knowledge Base)
I wholeheartedly agree that a bigger digger is not to be sniffed at.
I would however say that a traveller will soak up energy in a different way to stretchy line. Nylon stretches to absorb energy. Moving a weight vertically does mechanical work (1N through 1m etc.etc.), thus absorbing energy out of a snatch. I agree that when things are really tugging it won't help the angle of lay but it will lessen the sharp tugs. It's a slightly different thing to the size of the spade but all part of a system.
The problem with discussions like these is that there are years of experience, tips and tricks to communicate. There is no one rule and everyone tries to argue about oversimplifications. Seamanship, it's all about judgement, which of course is based on..............
I'd debate the some of the Rocna article a bit over a mug of tea. The hardest bit is getting rid of the last bit of curve, which is there in their data but they kinda move on quickly. I've worked a fair bit with catenic curves in my life, from long wire survey baselines (old school), sidescan tows and multi point anchor lays.
Ahem! I note Rocna says something encouraging about 8:1.....
