(7) Mid-pole Snuffer Bag [I use SNU from Dennis @ Barefoot Sailing]

Spinnaker Issues That I'm Running Into:

(1) How to run the Spinnaker Halyard? The spreaders and front diamond wire are in the way.
[I ran it through the spreader. -- No problems so far.]
Looking up the right side of the mast where the Spin. Halyard will Run

(2) How does the Main Halyard Make its way through the trampoline and into the Spinnaker Bag?
[The SNU bag, at its end towards the boat, has a grommet and two openings. I've not got a good system yet for routing the main halyard which must traverse from under the left side of the pole to the right, over the front right side of the front-crossbar, and then to the right side of the mast where I have my halyard block. It's the most challenging problem so far.]

(3) How to attach the mast Spinnaker Halyard Block?
 [ I chose to use a hard fixture instead of the line loop methods that I've seen online. I use a Bow shackle to allow the block to traverse around the mast. My block is approx. 26ft from the crossbar.]

Hobie 20 Mainsail Halyard Ring and Masthead Hook:

One common problem with Hobie Cats is how to hook/unhook the mainsail halyard ring on the masthead hook. In order to get this system to work well:

(1) The halyard knot must face the mast like the image below. [Center of the picture shows the main halyard, the halyard ring which sits on the hook, and the mainsail headplate]

Mainsail Headplate. Note the halyard knot facing towards the mast.
(2) The hook is on the right side of the mast, and the mast rotates. To hook the halyard ring, the mast must be rotated under the ring by a clockwise (when viewed from above) mast rotation. Haul up the mainsail the last 12 inches while pushing the mast rotation bar left. The opposite must be done when lowering the halyard -- a counterclockwise rotation to rotate the hook out of the way of the halyard ring as it is lowered down. This means pushing the mast rotation bar to the right.

Masthead hook. Located on Right hand side. This determines direction of rotation required.

(3) When raising and lowering the mainsail, the boat must be pointed directly into the wind. It is very important to have the boat de-powered and not have the mainsail cross-winded. Taking breeze from a-beam greatly increases track friction, and leads to a very difficult to hoist sail.

Here is the "Mast Rotator Bar" [Picture Center -- Detach the Mast Rotation Line from the Shackle 1st]

Here is a description of how the mainsail is supposed to be hoisted:

    Two shackle system for holding down tack and Jib Halyard. I want to switch to a soft shackle that I can tension somehow.

    Trampoline Track - Riveted to the boat and keeps jib car slug captive.
    I ground away the track towards the rear to pull my car slug out (not shown here)
    Very slim Hull cross section compared to the Hobie 18.
    The Hull is also seamless on the top side giving the boat a sleek, modern look.


    Current Two Shackle Method.
    Goal is to replace the halyard shackle with a soft-shackle.
