When you consider a catamarans speed you will need to keep in mind the boats weight and narrowness.
Is 30 knots fast for a boat. Knots Miles per hour. On the other hand for boats such as a trawler tug dingy sailboats and ski boats the speed of 30 knots is too fast unsafe and uneconomical. But boats such as yacht and ferry its fast safe but uneconomical.
So it depends on whether 30 knot is fast for your boat or its just average speed. But if youre talking about average speed for different boats. Yes 30 knot is fast enough to give the thrill.

However using a planing hull will make it ride like the wind at unbelievable speeds between 35-58mph or 30-50 knots or 55-92kmh. The planing hulls in racing sailboats are a key reason for their incredible speeds.
Is 30 knots fast for a boat. All of the above sre xorrect answers depending on your design intent. If you are considering fuel economy yes.
Racing sailboats can reach speeds of 30 - 50 knots 35-58 mph or 55-92 kmh. The record is set at 6545 knots 75 mph or 121 kmh. They can beat wind speed because they have a planing hull instead of a displacement hull making them a lot faster than average sailboats.
The reason that top-rated windsurfers can only do 30 knots where they live and not the 50 knots of the world record is wave action. Sailings world speed records are set on a stretch of water in France with a long sandy spoils beach that keeps wave action down in strong winds. The worlds fastest sailing catamaran formerly known as Orange and more recently Gitana 13 has been converted into a fast cruiser that is still capable of 30 knots under sail.
She has set quite a precedent for gobbling up nautical miles taking 43 days to sail New York to San Francisco 11 days from San Francisco to Yokohama and 41 days from Hong Kong to London. Keep in mind that one knot means a nautical mile per hour. Light wind has a wind speed between 1 and 4 knots.
Moderate wind means 15 to 19 knots of wind speed while strong winds are between 20 to 33 knots. A gale involves a wind speed of 34 up to 47 knots. Once the wind speed goes up to 48 to 63 knots this indicates a storm.

We couldnt believe it. With a max of 28 knots wind behind us from about 120 degrees we surfed down one wav. However some exceptional racing-designed cruising catamarans can reach up to 30 knots in the right wind conditions.
Factors That Impact Speed Weight Size. When you consider a catamarans speed you will need to keep in mind the boats weight and narrowness. Knots is how the speed of aircraft and boats is measured.
Both miles per hour and knots is a speed which is the number of units of distance that is covered for a certain amount of time. 1 knot 1 nautical mile per hour 6076 feet per hour 1 mph 1 mile per hour 5280 feet per hour.
