Welcome to the forum mjcayman.
You don't say what
boat you have, but I presume a
catamaran as you refer to "one bow".
I wouldn't bring the attachment point back to the windlass as this is nearer the centre of the
boat, and will cause it to weave back and forth. The usual
catamaran setup is for a Y shaped
bridle, with the end of the Y attached to the rode about 5 metres from the bow. Each leg is attached at the bow. Often these are permanently attached below the forebeam, but if they are cleated on the
deck, they can be individually adjusted.
However, with 50' of nylon out, you may find the stretch is a bit much unless the rode is quite substantial. With a strong gust, the nylon strecthes like a rubber band (the benefit of nylon). As the gust passes, the elasticity pulls you towards the
anchor again. Then when the next gust arrives there is more distance to be blown back, causing increased momentum. This also increases the tendency to weave from side to side, and puts increased pressure on the whole system.
If you don't want to increase your chain length, you can mitigate this somewhat by having a longer
bridle, but made out of oversize nylon. Just be aware that if the nylon can lie loose on the bottom, it could foul/abrade on rocks,
coral, etc.
