Hobie 20 Front Hull Boat Covers - Revisting with Dimensions

Application: I currently have Jasmine sitting on a boat trailer in the yard - these covers install on that trailer. This is the first set, the front hull covers, port and starboard.

Salt spray on the sea coast has a way of rapidly erroding covers and testing fabric life. I remade my front covers and here are some images if you are thinking of doing the same.

1. Front Covers Bill of Materials: 
1. 10 Yards of "Sunbrella" or any Solution Dyed Acrylic . You will have a bit of extra material.
1. I have tried other China-sourced materials including "Ottertex" and others which failed rapidly. Go with the Solution Dyed Acrylic.
2. Safety Pins to Pin the material to your boat hulls
3. Sewing Machine (I use my great grandmother's Singer 301A)
4. Polyester Outdoor thread similar to this: "Coats 108552 Outdoor Living Thread 200yd, White"
5. Front Cover, 1 for each hull, consists of a sock which zippers closed
6. Qty 2, #10 YKK Separating Zippers 67284 - White, 84" (Sailmaker's Supply https://www.sailmakerssupply.com/)

Starboard Hull cover - flap comes inward towards center of the boat to zip close from crossbar

Procedure:

1. I cut material with scissors but see others using a hot knife to stop material from threading-out/shedding. Next time I will try this method.
2. 24 inches to Tang, 26.5 inches to start of zipper from tip of front hull.
3. Hull circumference increases towards the crossbar. Pin cover in the closed position to tailor to hulls.
4. 1 hull cover is the mirror image of the other. Both "flap" towards the inside and zip from fore to aft.

My Port Cover came out too tight compared to my starboard cover. Measure dimensions carefully to prevent this and allow sufficient closure space for zipper (don't pin too tightly)

84" YKK Zipper, zips fore to aft

Dimensions of Circumference

1. 45 inches around the bow
2. 65 inches around at Cross bar
3. Lower seam 93 inches
4. Top seam to crossbar 120 inches from tip of bow to overlap with crossbar
