The Torresen Marine Rigging Department is consistently expanding it’s rigging services and techniques. The research and development for cordage and splicing is undergoing constant change. The opinion here is that this segment of the marine market is undergoing significant technical growth. The sky is the limit when it comes to cordage materials. Splicing techniques are only limited by a rigger’s imagination. In this article we explain basic selections for halyards based upon the size and use classification of different boats. In addition we explain the different splicing techniques that are commonly available. These are listed as Torresen Marine part numbers with description.
The Torresen Marine web site is being re-developed to include a new rigging web page. This page will reflect specific rigging services. Included in this site will be a halyard and control line selection guide. This guide will allow a customer to simply navigate through the selection process with their mouse. There will be an extensive boat selection library. One simply selects their boat, a specific halyard or control line, owner’s used shackle or new and any special splicing techniques. Once these selections are made, recommendations then will appear complete with pricing. Every step of the way the customer will be able to opt out of the process and go directly to the Torresen Marine Rigging Department e-mail where questions will normally be answered within the hour.
Here is an example chart to explain line recommendations for halyards. Cordage recommendations are Samson Rope Technologies specific. Other manufactures available are Yale, New England Ropes, and Gottfredi Mafioli to name a few.
Multiple halyard choices are boat size dependent. For instance, the first main halyard recommendation is for the smaller boat in the boat size range and the second recommendation is for the larger boat in the boat size range.
A note on eye splicing; splicing a shackle to a halyard maintains 90% of the lines safe working load. In contrast tying a shackle to a line with a halyard knot such as a bowline reduces the lines working load at the shackle by roughly 50%.
CLASS1 Splice: This is a core-to-cover eye splice for lines that have polyester covers and polyester cores. Samson XLS is an all polyester line in stock at the Torresen Marine Ship’s Store. The core and the cover are the same strength so they can be spliced together as an eye.
CLASS2 Splice: This is a core-to-core eye splice for any line that has core material that is stronger than the cover. High modulus polyethylene (HMPE) cores such as Technora, Vectran, DSK60, DSK75, and Spectra are such core materials. Lines of this variety that we stock at Torresen Marine are Samson’s Validator II, Warpspeed, XLS Extra, and Ultralite. The covers on these lines are merely polyesters for UV and abrasions resistance. Therefore the core must be spliced to itself in order to maintain the lines load capabilities.
TAPER Splice: This splice is used to strip the cover material from the halyard or control line in order to save weight. Lines that are taperable have core materials that are urethane coated for UV resistance and are color matched to the lines tracer color. Tapered lines use a TMISPLICESOLID for shackle attachments.
SOLID Splice: This splice is for HMPE 12 strand line (core less). This splice can be “luggage tagged” to the shackle thus making the shackle easily removable.
FLEMISH Splice: This splice is used to tie a “reeving” line onto the halyard tail so it can be pulled into the mast. This splice is not load bearing. It can only hold the weight of the line itself. This splice makes for a nicer termination to the line end than standard end whipping.
12S/COV Splice: This splice is for tapered halyards using 12 strand luggage tag splices. The final 2′ of this halyard has a Spectra jacket tapered onto the shackle end for additional abrasion resistance at the sheave box. In the first picture below we see two eye splices. The top is a core-cover eye splice (tmispliceclass1) and below it is a core-core eye splice (tmispliceclass2).
The lower picture shows a shortened model of a tapered halyard featuring a Flemish eye splice (tmispliceflemish), a Tapered splice (tmisplicetaper), and a 12 strand eye splice with a spectra chafe cover installed (tmisplice12s/cov). The 12 strand splice is “luggage-tagged” to the Tylaska shackle.
Please feel free to contact either John Schumacher or Matt Noren in the Torresen Marine Rigging Department to discuss specific cordage and splicing needs.
just bought a 1989 Com Pac 27/2 in time to haul it out for winter. Need to replace main and headsail halyards. factory saus 3/8″ by 81′ for both halyards.
Please price WarpSpeed 3/8 halyard with splice & shackle and whip end.
