Don't even think about it ... please
Samson Amsteel is wonderful suff no doubt, but not for lifelines on a boat. C Sherman Johnson has a line of fittings for using 1/4" Amsteel for lifelines. From their Catalog: "Johnson now offers its popular Life Line Fittings with eye ends for today's high-tech, low stretch line. Johnson recommends and sells 1/4" dia. AmSteel in grey from Samson. This line is a 12 strand single braid, 1/7th the weight of 1/4" 1x19 cable, offering the same strength for about the same cost. Johnson recommends changing out the line at three year intervals. Professional splicing recommended."Note two highlights, *change out at three year intervals* and *Professional splicing recommended*Cost Comparison:Amsteel: $147 Hardware, $70 Amsteel, 6 Splices @ $20 (if you can get a pro to do it for that) $120 = $337 for 1 lifeline on a 30-35 foot boat. Every 3 Years, you spend another $190 for line and splicing.3/16" 1x19 SS Cable: $160 Hardware, $39 Cable, 6 swages $60 = $259The Amsteel system works out to $78 more than SS Cable. The Cable will go 10 years. So after 10 years, the Amsteel option is $648 more PER lifeline.If anyone still thinks that it is a good idea (you do save 70% of the weight of the wire), consider this:3.14.6 Lifeline Minimum Diameters, Required Materials,Specificationsa) Lifelines shall be stranded stainless steel wire ofminimum diameter in table 8 below. Lifelines shallbe uncoated and used without close-fittingsleeving.**Notwithstanding 3.14.6 (a), temporary sleeving maybe fitted provided it is regularly removed forinspection**b) Grade 316 stainless wire is recommended. **c) A taut lanyard of synthetic rope may be used tosecure lifelines provided the gap it closes does notexceed 100 mm (4 in).**d) All wire, fittings, anchorage points, fixtures andlanyards shall comprise a lifeline enclosuresystem which has at all points at least thebreaking strength of the required lifeline wire.Note that coated lifelines are not legal for racing, neither is Amsteel.Don't even think about it, they are Life Lines.Randy
