We just went thru adding a spin to our 6.0. It also was an old or ex-worrel chute in the 420 sf range and it sheeted to the back beam. We bought a used spin pole, chute, snuffer head and some miscellaneous parts. Then, added the rest. I have some pictures somewhere. The tramp is and will be a mess. Jake provided a diagram on how to run a one line halyard-tack-snuffer line and that is how we have done it. Rick Bliss told me to not locate the halyard height any higher than 28’ I think. We followed the NE Chute spec in case we decided to upgrade to a new NE Chute. I’ll follow this up, right now I have to keep my kids from killing each other in the shower!
