Wind generator
Wind generators on yachts: charging in breeze, noise and mounting survey points, and FairHelm limits on claiming year-round amp-hours.
Vad det är
A wind generator is a small marine turbine that converts wind into DC charge for the battery bank, usually on a pole or arch aft, with a regulator to protect the bank.
Anchor
In windy Nordic anchorages output can help; in light summer air it may idle. FairHelm notes neighbour complaints, blade condition, and whether the unit is safely reachable for service.
FairHelm judgment
FairHelm judgment: wind is a useful supplement, not a free power plant. Noise and failing mounts sink deals faster than missing a few amp-hours. Pair expectations with real site wind, not brochure curves alone.
Limits
We do not invent average knots for your cruising ground. Cut-in speed, furling, and regulator type vary by model. Confirm service access before purchase.
Vanliga frågor
Q: Is wind better than solar?
A: Different patterns. Wind can charge at night or in gales at anchor. Solar wins in long sunny days. Many boats use both.
Q: Why do neighbours hate some units?
A: Blade noise and vibration. Ask how the boat sounds in 20 knots before you buy.
Q: Can a wind generator overcharge batteries?
A: A failed or missing regulator can. Confirm dump load or charge control matches the bank.
