2001 Nacra Inter 20 Restoration - Side Hoop Spinnaker Pole and Hoop Upgrade

Erik Lassen · 2021-01-03T19:06:00Z

Fellow Inter 20 CatSailors! The boat is currently setup to use the original end-pole spinnaker snuffer design. I'm trying to gather all the parts to upgrade the boat to use a mid-pole snuffer setup. So far I've already found a local metal tubing shop that sells 1.5 OD aluminum tube with .065" wall thickness out of 6063-T6 and is 12 feet long. I found a side hoop snuffer ring off ebay, and I've bought a spinnaker setup with the patches setup for a side pole hoop. I've also found and bought a side hoop spinnaker sock made by performance sails. The remaining items I need to find and figure out are: 1. The aluminum pole is raw and non-anodized. I've searched high and low trying to find a local source for a sunfish upper boom, and I've tried to order a new one off of the internet, but the freight shipping cost of a single boom makes it un-economical to order a single anodized pole. For the other Inter 20 folks who have made this swap do most folks find an anodized pole or do they paint them? Pay to anodize them? Or get the pole powder coated? I'm pretty sure the pole will oxidize pretty quickly if I leave it raw and primarily sail the boat in the ocean. 2. Does anyone have the dimensions conveniently available on what distance from the front cross beam the side hoop should mounted on the new spinnaker pole? I can make a guess based on the length of the sail sock, but I'd love a dimension from someone who has their side hoop setup sweet. 3. The end-pole plastic fitting that inserts onto the bracket mounted to the front crossbeam, is that a standard Nacra part I can order for the aluminum pole? I can machine one out of nylon at work, but that will take extra work and if I can simply order a part of the internet that is likely the fastest solution to get setup 4. On the bridle wires-spin pole bracket, my current bracket is sized for a 2" OD Carbon pole. Is there a similar standard Nacra part that replaces the old bracket for a pole with a 1.5" OD? I thought about machining a spacer to accommodate the new pole in the old bridle bracket, but I'm guessing this is also been previously solved. 5. Lastly, the current end pole snuffer is setup with a common spinnaker halyard that is also the snuffer retrieval line. There are a number of blocks and bungees under the tramp that I'm pretty sure are setup to route this halyard/snuffer line, but I haven't been able to figure out the rigging of running this line so that the bungees suck up the slack in the line. I've looked online and through the original I20 assembly manual, but I couldn't find anything. Anyone have a simple drawing or series of pictures that shows how to route the halyard under the tramp?

Want to high jack the thread here for just a minute since there are many I20 owners on here. I'm looking for the part number for the stud assembly that holds the mast rotator?
Mahalo!
And now back to spin poles...

Depends on what you have. Is it a carbon mast with the rotator near the goose neck, or is the rotator on the bottom . . . or do you have the newer aluminum wing mast?
