Re: RIP Cornelis van den Adel

Sad news indeed... He was a frequent and well liked participant at many swedish comps and will be missed. RIP.

Re: Q: How does hauling work?

Hi Bernd Why would rsp have to be in the same position? I agree it would be if the rod is stopped completely and immediately at the same position. But the rod is not stopped completely and immediately. The rod rotates a bit further after the "stop" in the hauled cast before it reaches rsp, because i...

Re: Covered topics /how it works

Hi Joakim I roughly agree 😉 try laying the line on the ground behind you, fully straight, make a slow forward cast throwing what starts as a super tight loop, and watch it morph bigger at the end of the cast. Cheers Lasse You opened my eyes :p I might give it a go this weekend. If I can arrange it ...

Re: Q: Why does a cast “collapse” if the casting stroke is started before the previous loop has straightened?

If the rodleg/straight line have some negative velocity when the forward stroke starts, then there could be a "kinetic capture" I agree. But pulling line through the loop is never going to give a higher linespeed in the end of the forward stroke. There is atleast one possible benefit though - slack ...

Re: Covered topics /how it works

Loops also morph the other way, ie. from small to big... just throwing that into the mix here 😉 And that has to do with line velocity and where the flyleg is coming from. Cheers Lasse Well.. if the line has more then one velocity just before loopformation anything could happen :sorcerer: ;) But i d...

Re: Covered topics /how it works

This tension, at the top of the loop, that is pulling the flyleg. How does it relate to loopsize? Does it increase or decrease with smaller loops?

What I understand is that the energy you spend to « pull back » the backward cast by an early restart is lost for the next forward one.
I am correct Joakim?

Merlin
I think so yes.

Re: Q: Why does a cast “collapse” if the casting stroke is started before the previous loop has straightened?

First of all - this isn't a problem in my casting. It is instead a branch off from this thread: https://www.sexyloops.co.uk/theboard/viewtopic.php?f=11&t=3323#p54992 I don't think my answer is the complete or best, but I do think it is a good starting point in to a discussion about it. I already see...

Q: How does hauling work?

There are two main reasons for hauling. * Distribution of work input between hands. * Maximum total work input. To keep it simple: Hauling adds linespeed directly to the line. The effect on the rod is somewhat counterintuitive though. In the distribution case of the hauled cast the rod hand does les...

Q: Why does a cast “collapse” if the casting stroke is started before the previous loop has straightened?

A: A part of the force in the casting stroke that should have been used to generate linespeed was instead used to stop/reverse the line. Remaining force was not enough to generate sufficient linespeed for the intended cast.
