Baller jdk99 Posted May 11, 2016 Baller Share Posted May 11, 2016 Last August @OB1 and @Edbrazil provided some great input on permanent course installation here: So we have begun the process but I had a few quick questions for you experts on the cross course setup specifically in reference to the image below: How far from the 'shore pin' should the 'downpull weight' be located? (need for hypotenuse calculation) How deep should the lowest portion of the crossline be at high water given a 2-3 foot water level fluctuation? (hypotenuse calculation again) How many pounds for the 'downpull weight'? Is the "compensator float" necessary? Any reason 1/2" hollow nylon twine couldnt be used instead of cable (much cheaper)? Once again, many thanks for all your help. Link to comment Share on other sites More sharing options...

Baller Edbrazil Posted May 12, 2016 Baller Share Posted May 12, 2016 This system was developed for the Miami courses, all 5 of them. Where it is deep-deep and uneven on the bottom. At one time, I did a SCUBA trip to the bottom there, and it was a good bit scary. If other variations work for you, fine. No reason to use crossline cable unless you are planning for a 'record' course. Just need to make sure that nothing is 'grounding out' on you. Crossline courses are a good solution for a lot of places. Andy's tie of Jeff Rodgers' record happened in the main Miami canal in 1998, and it was all done in a very Kosher manner. And certified in a short time. I created a survey spreadsheet for that situation, along with the math that describes the method. Nice way, as once the shore pins are 'shot', only angles are needed.
