Thanks for the pictures, so here is what i am thinking and have gathered. We have the pole and the mast attachment. rig the pole to the mast and to the sail, use the topping lift (which we do have) to hold the pole up and use our normal sheet winches to hold the pole down and back. And on the boom we can let the boom out and then rig a preventer from the end of the boom up to a pully near the bow and then back to the cockpit to a winch or a cleat. Sound right? Now is this only really used for strait down wind correct?

When sailing wing & wing, I always position the whisker pole perfectly parallel with the mainsail boom, while maintaining a perpendicular orientation of pole and boom to the wind direction from astern.

You will increase the risks of an accidental gybe if the point of sail becomes closer to a broad reach.

It's usually best to set a whisker pole when sailing wing 'n wing, as the others have suggested, but I often sail wung out without a whisker pole when I'm cruising shorthanded, and occasionally when racing. Sometimes in a race I want to head directly downwind on a puff for a short distance, so that, when I turn to head for the next mark, I'll be on a faster point of sail. In that case, we might not be sailing wung out for enough distance to justify setting the pole and taking it down. Setting the pole and preventer are good practices if you're going to be on that point of sail long enough, and especially if the wind is light, but you can also make small gains simply by jibing either the main or the jib and sailing wung out for shorter distances without a pole, especially in winds that are strong enough to keep the jib filled without a pole to hold it out.

I should note that rigging a whisker pole and rigging a preventer is a bit time consuming and if you are only going downwind for a short time, then typically you can free fly the jib (without a pole) and run wing and wing without rigging a preventer, as long as you pay attention.

I should also note that on most boats, in light to moderate winds, it is faster and safer to stay on a broad reach with your jib filled to leeward rather then run dead downwind.

I would also note, that few whisker poles are rigged to take a pole lift. Unlike a spinnaker pole which can be double ended, since most traditional whisker poles are single ended (meaning a latching hook at the mast and a non-latching pin or hook at the clew of the jib) and the pole is too long to do a dip pole jibe under the jib, jibing a whisker pole that does have a lift is a major pain in the butt and so since whisker poles are generally significantly lighter than spin poles, even on boats with whisker poles rigged to use a lift, a pole lift is generally not used with a whisker pole.

Lastly, since the death roll that can occur, if you accidentally jibe with a preventer set in heavy air, is more dangerous than the accidental jibe itself, preventers need to be easily eased. And since there are huge loads imparted into the boom and mast if the boom tip hits the water with a preventer rigged, preventers need to be resillient to absorb the shock. Offshore racers generally mount the preventer blocks on a resilient mounting. The use of a comparatively light nylon line (one size smaller than your jib sheet) is recommended for cruising boats.

Respectfully,
Jeff

This is one reason I like boom brakes over preventers... boom brakes still allow the boom to move, but keep the speed it can move at slow enough to avoid serious injuries. They don't require the user intervention that a preventer generally does.

One caveat on preventers—using too light a line can be more dangerous than not using a preventer at all, since the sail can really load up and if the preventer line lets go unexpectedly, it can have a lot more stored energy in it than if it had been free to move by itself. So, don't go down too much on the line size for the preventer.

You know what the first rule of sailing is? ...Love. You can learn all the math in the 'verse, but you take
a boat to the sea you don't love, she'll shake you off just as sure as the turning of the worlds. Love keeps
her going when she oughta fall down, tells you she's hurting 'fore she keens. Makes her a home.

Hi

here is a pic.

I use a preventer on my main, using the same boomvang.

on the spinnaker pole, I use a tooping lift and a downhall. the ring is place 6 feet on the mast.

oh, one more thing, make sure the wisker pole latch hook and the ring you attach it to are matched in size correcty. It's entirely possible to break something due to binding if the mast ring is way too large for the latch. I think most wisker poles are designed to match with a certain diameter ring that transfers the forces correctly.
