I have never used Cajun Ropes, so I don't know anything about them directly. But as I understand it they use Nova Braid as a manufacturer, and they have an exallent reputation. Their prices seem to be very reasonable, and the options seem to be reasonable.
Before I did anything though, I would highly recommend you consider getting rid of double braided polyester lines (sta-set and the ilk). While polyester has been a good standby for cruisers for decades, modern lines are much stronger and much cheaper than many realize.
For most applications a modern dyneema/spectra line can actually be much cheaper than the polyester lines it might replace. My new halyards for instance cost 2/3 as much by going to tapered endurabraid as the sta-set would have cost. And have a fraction of the stretch, are thinner so they run through blocks easier, are much more uv stable, and don't absorb water.
I'm Glad to hear. I just re-rigged a Cal 36, all hallyard's, sheets etc. We saved over 500 dollars buying a spool on some web-site. It came to about .20 cents a foot. All 5/8. I'll check on Cajun next time I just need one line or what ever.
Capt. What did ou need 5/8 for on a Cal 38? That is massive stuff for that boat. Heck you could pick up the entire boat with a piece of that line, without coming close to breaking strength. I would be concerned that none of the other hardware would be sized appropriately for something that big (blocks, sheaves, clutches, ect).
