Yep, I have seen this trip for a couple of years now on the Dutch beaches.



It does have the drawback of requiring a rather small diamerter line for the spi halyard when used.



However the technic use (lineair springs) is easy to homemake. Actually I was planning to make a setup myself for my own F16. I was also planning to make a document out of it and place in the Tech Corner of the F16 website. For I really dig the fact that F16 class has for some reason attracted innovation ex : Tramp launched spi, T-foil rudders (stealth), two piece Carbon masts (Bimare-Riba), lightweight Thrust bar rudder kick-up system and daggerboard raising setups (Taipan 4.9). I think it is thrilling to see ALL of these new things, as well as aspects of other classes like selftacking jibs, to be features on designs in a single class. The class is really going with the trend and presenting the newest in sailing. I would very much like to contribute to that.



I will post a few preliminairy pics I have on this page later.



Now lets hope to Bob develops the dolphin striker less beam from carbon succesfully.



Anyways



If you homemake it the retiever then it would probably costs somewhere around 20-25 Euros.



It would set on the outside of the rearbeam and coil up the excess halyard. The halyard would run over the trampoline from the cleat near the mast to the middle of the rearbeam and dive under the rearbeam to reach the winding coil. This line would constant be under slight tension and would wind up any excess line without pressing a button or anything.



See picture in next post.
