No sails – maybe use of drift anchor or similar
For a new inexperienced crew, we do not recommend sailing in more wind than
max 16 knots or 4 Beaufort of true wind, before knowing the boat better!
IMPORTANT – If this diagram is not respected, Quorning Boats ApS and dealers
cannot be held responsible for boat, crew and/or gear. Beware that the boat can
capsize, if not handled correctly. For downwind sailing if "solid" seawater gets
over the center hull bow or float bow – this is the first warning to reduce sail. If
the wind is "gusty", make sure to be ready to release the sheets quickly – by
holding the sheets in your hands ready to let go.
