When inputting sizes please do so in metres including fenders, bowsprits, boarding ladders, davits including their loads, stern drives, out drives, rudders, anchors, pulpits, push pits and any other extension fore and/or aft of the boat. If you do not own a boat please enter estimated details as we use this data to determine if a mooring is suitable.

All measured from the water surface. Add 10cm (4in) to your sea water draught to compensate for reduced buoyancy in fresh water and allow for the extra weight of extra equipment, fuel and water which may increase your draught. Leave a safety margin for underkeel clearance and for fluctuating water levels, which may effect channel depth and headroom.
