Bit of a long story how we came to get the net, but by looking at their website they are in to bigger vessel rescue systems in the main. Their web address ishttp://www.markusnet.com/product.htm
Main man is an Icelandic guy Petur Peturson who lives in Glasgow-so thats two accents to sort out if you talk to him! Best to e mail him from the site and mention that it is the one we have on our boat.
Really good bit of kit, but not cheap. Stows away in its own velcroed bag out ouf the way between tube and deck so that you forget its there-til you need it! You have to supply your own blonde to practise with!
