Hi Perry,
firstly thanks for your welcome to the fold!
Regarding Dyneema for shrouds and forestay, I do know of one Broads river cruiser with an enormous spread of sail using Dyneema for all standing rigging and works very well. Apart from the weight saving, (probably insignificant on a Seahawk), is has less stretch than wire and gentler to handle.
The jib furling usually consists of a luff spar with slot for the sail, which the forestay runs through, a top swivel which the halyard attaches to, and a bottom drum which the furling line runs round. The forestay comes out the bottom and is then either attached to a bottlescrew or a stainless plate which in turn attaches to the stemhead fitting. On a couple of boats I've worked on, I designed an 'A' frame which has a prong on the end of it which has a pin and 'R' clip attaching it to the stainless plate. A simple block and tackle attaches to the bottom of the frame and by releasing the plate from the stemhead fitting the tackle can be played out to lower the mast. Once down, the 'R' clip is released, the frame and luff spar are lowered to the deck. If you know what I mean!
cheers
Mat
