After witnessing the winging onslaught in the San Francisco Bay Area I have started to wonder if it might be possible to imporve our beloved "fins". What I think is good about winging is its free-ride appeal. It is slow, but it is also easy and it has a large wind range. It would seem that windsurf development got stuck somehow into high performance ... great, fast, extreme but still with limited range and very hard to handle. Is there something that can be done bring in some new ground braking development?
Maybe fins? Almost by chance I have been playing with very large fins set up with my FSW 90. 25 + 11 sides. with 5.4. That is quite massive at my weight but I am surprised by the increased uptake in upwind and low end. I loose about 1 knot of top speed, but my range of use is larger.
So, retractable fins? Dagger boards are retractable, is there a way to have fin boxes that do the same? Maybe just for the sides?
Hybrid foil-fins? Yes, they disappeared quick, but that might be because they did not show any advantage in racing conditions. Could they work as freeride range extender devices?
Board shapes? A modern 95 can handle the same wind of on old (say pre-2010) 85. Is there something more to do. Shorter, longer, wider in the tail ... whatever! Or shape shifting? Is it so hard to make a board tail that can change shape while sailing?
OR SOMETHING ELSE. I am no engineer. ANYTHING to make windsurfing EASIER AND RANGIER?
The variety of windsurfing gear is still huge. Each manufacturer has multiple wave, free wave, free style, free ride, free race, slalom speed and OD boards and sails with a bewildering combinations of rockers, concaves, rail shapes, width, length, fins and centre boards for boards and shapes, aspect ratio, battens, cambers / no cambers, leach and materials for sails.
Extending low wind range requires either wider boards / longer fins / larger sails or longer boards. Both have their advantages and disadvantages.
Extending range for one board / fin / sail is a function of design. Adjustable downhaul and outhaul increases the range of a sail. Rocker, concaves, bevelled rails and raked fins increase the range of a board of a given width and volume. There are compromises in terms of speed and agility associated with these design choices, but if you just want to mow the lawn, they still work.
There is still a lower wind limit associated with any design. At 88 kgs my 115 litre slalom board with 7.8m sail is about 13 kts. I can still use this gear in up to 20kts. Each of my 3 board / sail quivers have about a 8 knot range eg
115/7.8 13 to 20
97/7 16 to 23
80/6.2 20 to 27
I could increase this range with a 137/9 combo but I just don't enjoy using this gear. I prefer to Windfoil.
If you think of windfoiling and winging as an extension of windsurfing then these are the design development you are looking for. If it's not your thing then continue to enjoy your finning. I just don't think there is a silver bullet that will make windsurfing more accessible.
