How did sailing ships sail up rivers?
Depends which way the wind was blowing! With the wind behind you, no problem. With the wind against you, 4 possibilities: 1) Tack; most vessels, especially if fore-and-aft rigged, which river boats usually were, can sail at a wide angle into the wind; in a wide river, one can thus go from side to side, put about and go back towards the other side, constantly gaining headway. 2) Club-hauling. Sail across the wind, getting up speed; at the end of the run, drop all sails, turn upwind, and coast for as long as possible. Then up sails and do it all again. 3) If the worst comes to the worst, kedging. Put a small anchor in a boat, send the boat upstream to the length of your cable, drop the anchor, haul in on the cable until you reach the anchor. Meanwhile, the boat has gone ahead with another anchor, and the process can be repeated. 4) If the river is not very wide, tow with horses or oxen (or, in many cases, the wife) from the bank. On particularly fast-flowing rivers, like the Dordogne in France, you simply didn't sail upstream. You built a raftlike boat at the headwaters, loaded it with trade goods, floated down the river, and at the mout sold the trade gooda AND the timber from which the boat was made. Then you got on the horse you'd taken with you and went home.
Why was the triangular lateen sail an improvment over the old square-rigged sail?
The lateen sail was used at the same time a square sail was used, but has different uses.
The square sail is fine if you have a heavy boat and always fiind a wind that is blowing in the direction you want to go. Under such conditions, a lateen sail isn't much of an improvement. It was only once boats were made lighter (to faster get from the Atlantic to the Orient) that the triangular sails were an advantage.
Also, if the wind is often blowing sideways to the way you want to go, a square sail, even if angled, doesn't work as well as a lateen sail. A triangular sail actually has a bit of lift to it so you can point your boat closer to the eye of the wind and still sail. This makes it ideal for sailing in and out of harbors and along the coasts. So small boats orginated the lateen sail for dexterity.
Depending on the size, type and rigging required they can cost many thousands for a large vessel.
A piece of string or rope?! You are probably asking about the 'knots' used at sea as a measure of speed. One knot = one nautical mile per hour. Don't ever say 'knots per hour', the word 'knot' encompasses the whole thing.
A power driven vessel is often understood to be a mechanically driven boat. Human power as in rowing or wind driven power is not usually considered power driven.
Would you please use 'aft' in a proper sentence?
Get aft before the bow sinks any further!
Let's go aft!
The aft anchor will be found in the aft locker.
Where did Sir Peter Blake go to school?
Sir Peter Blake was from Auckland, NZ, and went to school there. He later attended Auckland Technical Institute, but I believe he quit to sail professionally before finishing.
What is a small one-masted vessel with mainsail and jib?
a dinghy would be a small (6 to 16 foot) sailboat, these can have almost any sail rig. the type of rig you described is called a sloop. a sloop is a sailboat with a triangular mainsail and a jib (this sail configuration is called a marconi rig, or bermudian rig), and are very common. so a small, one masted vessel with a mainsail and jib would just be called a sloop, or dinghy.
How long does it take to sail from Miami Florida to Severna Park Maryland?
That's about 950 nautical miles. Because the trip is heavily dependent on the winds as well as help from the Gulf Stream, an accurate time frame would not be feasible. However, if you can manage travelling 24 hours per day at about an average of 2 knots and no weather troubles, you calculate 950 nmi divided by 2 knots to get 475 hours or almost 20 days. However, a prudent sailor will add half of that for guestimation, call it a month. Of course, It's entirely possible, with everything going your way, you could average 5 knots which would be about 8 days, call it 12 days to be safe. Quick ball park wild guess: 2 to 4 weeks.
What is opposite of windward-sailing term?
That would be leeward, pronounced 'loo-ard'.
Sometimes crossword puzzlers are more tricky than that, not wanting an exact antonym, so 'alee' might also fit.
How fast does a sailing boat go?
------------------------
A sailboat's speed is directly proportional to wind speed and hull design. The longest distance in 24 hours and the fastest circumnavigation are currently held by a trimaran and the short-course speed record is currently is currently held by a multihull built specifically for the attempt.
For you and I sailing our fiberglass monohulls on the weekends, we are having a great day if we hit 10 or 12 knots.
------------------------
A sailboat can reach 30 miles per hour. There are two general types of sailboats, displacement type (monohull) and non-displacement type (catamarans, trimarans). The top speed of a displacement sailboat is based upon its waterline length because it sits in the water and cannot climb above the wall of water in front of it as it travels. This is calculated by taking the square root of its waterline length and multiplying by 1.3. The top speed of a non-displacement sailboat is limited by the sailboat design, the speed of the wind, and their point of sail - these sailboats can go much faster than the speed of the wind that is powering them, and are the fastest sailboats.
Is a 1974 Johnson 9.9 boat motor 2 stroke or 4 stroke?
The 1974 is a two stroke and weighs approximately 72 lbs. The four stroke equivalent from Johnson today is a little over 100 lbs.
1971 35ft Coronado Sailboat from California to Hawaii?
no problem, if your equipment is good, and you have ocean sailing expierence, go for it.
Heaving line is a relatively light line than can be thrown from aboard a vessel to the shore, to another vessel or from the shore to a vessel.
The heaving line is connected to the actual line/hawser/rope that we wish to transfer between the endpoints but is too heavy to be thrown by itself.
Once the heaving line is transfered, it is used to transfer the heavy line between the two end points.
It is customary to weigh the throwable end of the heaving line to facilitate the throwing process, with a weight, e.g. a 'monkey fist' knot.
Sailing was invented for transport purposes at first. When the land ends, in order for ancient tribes and civilisations to expand their howizons, they had to somehow get over oceanic areas. It is impossible to trace exactly who first came up with the idea of tying pieces of wood together in order to float. It is thought that pieces of wood would have been used to propell the boat through the water as a conventional version of rowing. At some stage, large sheets of canvas were hung up to capture the and use the power of the wind to speed up movwement. That, to my knowledge, is why sailing was invented. So ancient civilisations could gain an advantage on others by moving through the water the fastest and for the longest.
sailboat spars include the:
mast
boom
sprit (if the boat has one)
