Designed for optimum range at 7.5kts she achieves this at about 800rpm in flat water, and uses a little over 1L/mile. Cruising range is conservatively 3500 miles. To sail well needs 18-30kts of wind, but decks stay very dry and in all conditions she is easily handled by 2 people and not hard to single hand.
