I replaced the PVC tubes on my Zodiac Yachtline 530 this summer and have the old ones sitting around. They'll need to have the bolt rope re-glued but they hold air well and are in pretty good condition (at least the parts that were cleanable while mounted to the boat). If you could use them, let me know. I'm in the Philadelphia, PA area...
Unfortunately they are not. FWIW I learned that the medline 550 used the same hull mold as the yachtline 530. The medline tubes have a bow mounted anchor roller that just barely fits under my railing mounted bow nav light. I’d prefer it didn’t have this but I’m happy with the new tubes.
