When I first purchased a Rave, I managed to find someone selling the wand de-latching kit and purchased it. The point of de-latching is to reduce the drag of the wands with the foils lowered while the boat is sailing but not foiling. In the meantime, before installing the de-latch kit ...
After just a couple times sailing a Rave, I began to think that the Rave designers meant to rely on lift from the foils to raise them prior to a shallow water landing, or to have crew walk to the amas and raise the foils manually. But if sailing alone and not feeling that the boat would behave without someone actively piloting, the way to raise the foils would be to pull and hold the foil lock in its released position, sail forward at sufficient speed, and the foil will lift to a higher position instead of the foil lifting the boat. Once at the higher position, allow the foil lock to engage and hold the foil up. But what if the wind speed has fallen off by the time one wishes to land? Due to lack of forward speed, there won't be sufficient foil lift to raise the foils.
A few Rave sailors before me had devised foil uphauls/outhauls/cranes to allow a seated pilot to fully raise the foils. This not only allowed for shallow landing preparations in times of low wind, but allowed for the reduction of wand and foil drag when sailing at lower speeds. If I added 'cranes' to the Rave I felt I wouldn't need the wand de-latching kits.
Here's a short video of one of the cranes lifting and lowering a foil while the boat is on its trailer: YouTube: A Hydrofoil Uphaul/Outhaul Crane for the Windrider Rave Sailboat
Here are a series of images describing the build I used: Pinterest: Windrider Rave Foil Uphaul Crane
I realize there's not much interest in this these days, but there may be one or two Rave sailors who might benefit from this.
