After reviewing in detail the Para-Tech’s instruction manual on the additional components needed to properly rig the Para-Tech sea anchor we ordered the following items on 14 October 2015 from Defender's and Go2Marine's websites.

  • For the trip line we selected yellow R&W Polypropylene Floating 3-Strand Rope with diameter 1/4" x 150' long, at a cost of $22.99, with rated strength of 1250lbs.
  • For the sea anchor primary float buoy selected a red Polyform A-2 Commercial Grade Buoy size 14.5" x 19.5", at a cost of $43.99, with buoyancy of 68lbs which was within the manuals recommendation of buoyancy of 60lbs.
  • For the sea anchor trip line recovery buoy we selected a red Polyform A-0 Commercial Grade Buoy size 8" x 11.5", at a cost of $25.99, with buoyancy of 13lbs which the manual did not state a specific recommendation.
  • For the anchor rope we selected a full spool of white Continental Western Nylon Double Braid Rope with diameter 5/8" X 600' long, at a cost of $451.01, with rated strength of 13200lbs which matches the manuals recommendation of 5/8" size rope.
  • For the anchor chain, to increase the "catenary effect", we selected Acco G-4 Hi-Test galvanized chain size 1/2"x10' long, at a cost of $60.60, with Working Load Limit (WLL) of 9200lbs. This chain weighs 2.54lbs per foot, so a 10 foot length adds about 25lbs to system weight for catenary effect.  The manual recommended a 3/8" chain size however the WLL is only 5400lbs for that size.
  • To connect the ends of the chain we selected two 1/2" Crosby G-209A Series Forged Alloy Anchor Shackles, at a cost of $19.31 each, with WLL of 3.3 tons.
  • To connect the sea anchor float line to the primary float buoy we selected one 3/8" Suncor Stainless Steel Jaw & Jaw Swivel, at a cost of $22.99, with WLL of 1540lbs.
  • To put line eyes in the 5/8" anchor rode we selected two 5/8" Sea-Dog Heavy Duty Thimbles, at a cost of $7.19 each, and two 5/8" Sea-Dog Nylon Thimbles, at a cost of $1.99 each.
  • For the bridle connection we selected two Lewmar Size 3 Snatch Blocks, at a cost of $268.24 each, with WLL of 4750lbs.

 

These were shipped to our balikbayan box consolidator and forwarder Manila Forwarder in Los Angles, California and all items were received there by 22 October 2015. We received these items in Naga City, Cebu on 28 December 2015.
