Posts: 3,114 BANNED | I crossed paths with a furling drum and swivel in a box of spare parts from our club. Since harken parts # 434 and 435 are identical dimensionally but differ in load tolerances, I emailed them and asked them if there was a way to find out. They said take it apart, and look at the color of the bearings, if they are green, then its the highload, if they are white or black, then the drum is the standard 500lbs load.
Now I openned it up, and the bearings were not green, they were not white, and they were not black, but rather a rather unfavorable shade of puke-brown. It looks like it may have been green at some point in time, but considering that these bearings aren't exposed to UV light, then I'm less inclined to believe that they got faded.
I was wondering if it was a good idea to put this on my H17 that has no furling hardware for the jib. If the max load of the drum is 500lbs, does that mean that the forestay is gonna break free, or does it simply mean that the drum will not turn, therefore eliminating the furling action?
Thanks for your help!

Sounds like you have the high load furler. I would agree with your assessment that the worst case is that the thing won't rotate - but I would check elsewhere as a) I'm no expert in this area and b) that would be an ugly demasting.

Thanks

Posts: 342 Lake Murray, SC,USA | Any reason you can't just buy a 17 Sport Forestay? How did you convert your old forestay bridle to the new length? If you just added a couple short wires without the foil, I'd be real concerned that you were putting extreme stress on the hulls. The 17 hull is light, would increase the risk of fracturing/collapsing a hull with loading the stress in the direction pulling inward instead of up. The factory front foil is the same stock as a H-17 boom, but I would think any sort of reinforced aluminum tube would work just as well the only point of the foil on the 17 is to keep the working loads on the hulls in the directions for which it is designed, not pulling both hulls inward. If you coupled that with the pressure of the water pushing in the same direction that the forestay is pulling, you have drastically increased the load and are probably looking at a stress failure of the hulls at some point when you're having the most fun.
