Post subject: | Variation of the double bungee method |
Hi, after reading about fellow forum members solving floppy akas with double bungees, i decided to try it myself. my front akas now have 3/8 bungees with tubular nylon sleeves to reduce UV deterioration. I also made them MUCH tighter. my rear akas have a much different and involved method. using the screw in pad eyes, i drilled a hole, and inserted the oem Hobie bungee. in addition to the oem bungee is tubular webbing. one end is doubled over and run though itself. the other end is zip tied together. the oem bungee is inside the webbing and the webbing pulled very tight have yet to try it, but very excited... cheers, j |

Kayakman, I really like your idea of experimenting with the tubular nylon sleeve. It should provide both an additional layer of UV protection and possibly even chafe protection. What are your observations? |

Finally had the boat out and got to test the new bungees. They were bomb proof in light weather with lots of boat wakes, but the real test will come when I try it in some heavier weather. Cheers and Happy New Year! J |

I have only had my new TI for a month but already found the bungee on the armas is stretching far too much as well as most of the other bungee has stretched and lost it's tension. I am mostly sailing in windy conditions 15 to 20 knots is common and Ihave been in 25 to 30knots on the way home from a long trip. I might have to try your idea. |

Post subject: | Re: Variation of the double bungee method |
it's actually two ideas. one is merely a thicker bungee with a suncover and the other is the stock bungee with webbing tightened up to provide some (maybe all) resistance to movement. not sure which will work best. i haven't been out in the sort of weather that stresses them yet. they are both exceptionally tight, i never remove them. i need a lever to encourage the bungees into place. j |

Thanks kayakman7, Yes I see on having a closer look at your photos, that you have only needed to replace the screw-in plugs to loops on the rear. These things take a long time to get hold of over here in West Aus (several weeks) and if I needed 8 (to replace all the plugs) there would be 50 bucks or more. I thought about using rope to replace bungee but see that it needs at least some flex in order to turn as the arma folds in. I also noticed on my last sail that it is mainly the front end of the arma that is coming loose when I have it up out of the water. Last Sunday afternoon, I went for a quick sail with my son in 20 to 25 knot afternoon sea breeze, there was swell of about 2m (6 feet) and waves or wind chop of about 0.5 to 1.m (2 to 4 feet). I had the outriggers out of the water for a lot of the time and almost lost the front of one when the bungee stretched so far that the arma pulled part way out and stuck there as a big wave came through. We came in at that stage. So I am now thinking that the semi rigid tube with bungee through (like you have on the rear), might be my best bet for the front. |

I had several opportunities to use the TI in bigger waves and more wind and I've found that either method works superbly well. I haven't heard the ama's bounce since I changed the mountings. j |

Georde - You don't need to buy more srew in fittings just rearrange the many you have. I don't use half the fittings supplied. |

For now, you can pinch the padeye fittings off the front and rear of the amas, but it's good to have them there as well as potential tiedowns. Clear hydraulic tubing works great to cover a single bungie line. Even surgical tubing. I have found that using redundant bungee lines, each going to a separate Aka retainer post is a safe and reliable way to keep the floats on your boat. One bungee can be detached for easier folding. While your at it, you might try adding one of those nylon strap loops that hobie supplies on their paddle holder side bungees. They act as bungee pull tabs and will make quick work of stretching the Ama bungees, without crushing your knuckles. |

I added the second bungees to the original fittings. I stretched the original bungee to make it thin. I then looped heavy (50#) fishing line through the hole and then back again the capture the new bungee. I then pulled hard and popped the new bungee through and tied an overhand know and trimmed. Then placed the knots so they both would fit. Seven more times and I was done. Just watch your knuckles when the new bungee pulls through the hole as the fishing line pulls free leaving your hand to go flying into anything within range. |

Bob, Nohuhu, Thanks glad you like it. You know in the last year or so, we've all benefitted greatly from reading articles about how we're trying to solve this particular problem. Folks like you, Stringy, Yakass, Roadrunner, KayakingBob, Kayakman and several others who freely contribute their knowledge and expertise is all well appreciated. viewtopic.php?f=75&t=30065&p=122622&hilit=double+bungee#p122622 I'm sure I must have had some of these previous ideas kicking around in the back of my head when I came up with this solution. I just like the simplicity of it and it works. I'd be curious to know what the design engineers at Hobie think about it though. Might they consider implementing it in their production line or offering the necessary parts as a repair kit. Matt, Jbernier what do you think? |
