Just to let you know Spin-Tec has a halyard
accessory that takes the sail up and down. It is a very slick, perfectly engineered device that hooks the sail to the top bail and releases the sail just the same.
It's quite simple. When you want to get your sail down you attach the bitter ends of a halyard to the halyard accessory that is mounted on the forestay, hoist it up and it releases the hook with the sail attached and the sail comes sliding down along with the halyard accessory.
When you want to raise the sail back up you feed the head
of the sail with the hook in to the halyard accessory that is attached to the forestay and hoist it with the bitter ends of a halyard attached, it hooks on at the top bail and the halyard accessory is brought down with the messanger line. At that point both ends of the halyard are free and are able to be released. The halyard accessory can stay on the forestay or easily be removed and stored.
The design is similar to what is used on the America's Cup boats.
No halyard wrap, no moving parts
aloft, less compression
loads imparted on the system. Sails
last longer and no need for heavy reinforcement patches and large grommets. There are no maintenance
issues with this system...EVER.
About the tack point: the drum is adjustable making the tack point adjustable to fit your needs.
Hope this helps.
