Replacing Sea Rig Hardware with Swages or Compression Fittings
 

We have recently bought our Stevens 47 (predecessor to the Hylas 47 and 49) in preparation for a long term cruise with the kids. The present standing rigging has been up for approx 14 years (3/8 on lowers, 1/2 dyform on cap shrouds and forestay/backstay). The lower fittings are pretty slick looking Sea Rig turnbuckles (screwjacks ?) and the upper fittings are swages.

Unfortunately Sea Rig advised that their fittings are only good for seven years so we are looking to replace them as well as the wire.

The present thought is to use the same dimensions for the wire except just 316 1x19 vice dyform.

The main question is on the lower fittings: we have been recommended to use a regular swage fitting on the top and bottom fittings whereas my research (and research only - no practical experience in the matter) touts the virtues of the various compression fittings (Norsemen, Sta-Loc, etc). For the additional cost, is it worthwhile going with a compression type fitting ? The local rigger indicated that the swages on his machine would be more reliable than what could be done with a compression fitting. While I understand that the compression fittings can be redone in the field, is it worth going to them for increased reliability ?

Already gone to the expense and hassle of pulling chainplates. Would be frustrating to lose the rig because of the fittings.

Much thanks in advance.

Hello,
First, there is nothing inherently "more reliable" about a swage. Far from it. Whatever terminals you go with, just make sure they are assembled correctly.
As for value, the cost difference is typically a wash once you change out the rigging a second time. This assumes we are talking about rotary swages (I definitely unrecommend Kearney"s), and that you get a fair price on the compression terminals.
If you don't plan to sail South, don't bother with compression terminals. If you do, in addition to the long-term cost savings of Sta-Lok and similar, you get inspectability, invertability, and the ability to put everything together yourself.
So, what kind of swaging machine are we talking about? Whose wire? What is a recent batch test of ultimate strength? What does a recent metallurgical report say? If your rigger can't or won't answer all these questions, there might be reason to look elsewhere, regardless of terminal type.
Fair leads,

Much thanks. South is most definitely the destination and Sta Lok or Hi-Mod it will be.
