The Captain requested a new line bag to hang off the boom attachments. You know for reefing and outhaul lines. The bag needed to be sturdy and be able to stand up to weather. He requested a 14” square bag with pockets on both sides. Here’s what I came up with.
D Rings or Buckles
– Measure size of backing panel and add an 1” for seams. Cut 2 out of Phifertex Plus. Measure and cut 2 panels out of the mesh the same size. Measure and cut sides and bottom out of mesh 3” wide plus an 1” for seams. Cut enough for both sides of the bag so you have two pockets. Since my bag is square I was able to cut 6 of the same size for the sides. You will want a paper patterns because you just can’t mark the mesh well.
– Sew the 2 mesh sides to the mesh base with 1/2” seams so you end up with three mesh segments to make the U shape for the sides. Be sure your seams are facing the same way! You can make one side first to be sure you have it right or sew the pieces for each side at the same time. Your call.
– Sew the 3 sides to the mesh front panel for each side. Secret Trick: You may want to use the binder clips to hold the mesh in place as you get ready to sew.
– Cut with a hot knife a piece of webbing the width of the top less 1” of the bag for both sides. Stitch to the top of the mesh starting 1/2” in from the edge. Starting in from the edge will reduce the thickness on the sides by stopping before the seam. Fold over the webbing and stitch down. This will reinforce the top of the opening of the bag.
– Add a piece of webbing to the top of the Phifertex backing panel 1/2” down from the top edge and 1/2” in from the side edge. This will also provide some stability across the top of the line bag while reducing extra thickness in the seam area.
– Decide how you will attach the line bag to the boom. Stitch webbing to the back panel. I made the straps the length of the bag less 1/2” so it ended before the bottom seam and 2 feet of webbing to use for the attachment points. Position with Seamstick tape. Stitch on both edges.
– Attach the front mesh piece to the Phifertex backing panel with binder clips and/or masking tape. The mesh piece should be right sides out on the right side of the Phifertex panel. You will bind the outside edge so the seam will be covered by the binding. Not often that you sew right sides out, right?
– With both sides completed, attach the back panels using the clips to hold the panels in place. Sew 1/2” seam around the 4 sides. Watch that you don’t catch the mesh or the webbing straps in your seam.
– With the binder attachment in place, feed through the bag edge so it is tight against the binder feeder area and is tight in the binding. Corners: I carefully turned the corners through the binder, but you could stop at each corner or cut round the corners for a cleaner look. Sailrite has a video showing how to put the binding on with or without the attachment and neatly position the binding with a 45 degree fold. Turn under at the end and stitch down or carefully cut or hot knife the end and stitch it down.
– You may want to stitch in the top of the opening about 1” in at the top tapering about 3” down to the side seam to shore up the opening.
– Test the bag on the boom for attachment points. Add plastic D rings, buckles or clips.
Secret Tricks: Double stitch seams for durability. And give a bit of a pull on the mesh as you sew it so it doesn’t pucker.
Update: Version 2.0 Captain requested a revision for the buckles instead of swivel hooks attaching to the boom D rings. With my trusty friends, the seam ripper and hot knife, I took off the straps. I moved them closer to the edge and added a buckle. Much better now.
