SUN SAIL 07
a fabric shade attached to the boom sail cover with zippers and supported by fiberglass poles on the outside corners. straps tension the cover over the fiberglass poles.
the sketches here are incomplete as of 6/29/2024.
Changes
- raised the top of the bimini to the top of the boom where it will zipper to the sail cover.
- changed the orientation of the forward fiberglass rods to accommodate dodger attachment at the front instead of the boom.
- lowered the bottom of the shade for more protection
- the dodger has tubing added to attach the sun shade at the front and provide visibility.
Notes
- fiberglass poles are light and flexible, easier to store
- fiberglass tubes are shown as a single line rather than with its actual diameter which tapers from about 5cm to about .5cm.
- straps to tension the shade over the poles and to the front at the boom are not shown.
- the forward attachment may be on the dodger or the deck
- The boom is only tensioned and not rigidly fixed. the bimini supported by flexible poles will "wobble" back and forth as the boat rolls and pitches, swinging the boom about. If this is a problem, two poles could be added from the sheet traveler to fix the end of the boom.
in the comments below, please record other changes that need to be made.

ReplyDelete1.Poles are too stiff. We broke them trying to get the correct bend.
2. Fix the boom in place so it doesn't swing.
3.
3. The poles are both too weak and too stiff. Too stiff to get the correct bend withouth breaking, too weak to hold the heavy fabric in the thin flexible sections.
Delete4. Canvas man suggests using the heavy, large diameter poles. They will be strong enough to hold the fabric and flexible enough to provide tension to keep the fabric tight
