USEFUL SAILING HINTS, TIPS, METHODS, GADGETS & DODGES


These have been culled from various sources over many years and are listed here in no particular order and may prove useful to YOSC Members. Some are from that delightful old book "The Yachtsman's Weekend Book" by John Irving and Douglas Service, some from the Internet with kind permission from Lou Lancaster and others from miscellaneous sources including YOSC Members. I am sure that our Members will be able to add to these, so let me have them for inclusion in the next edition.

Maximum Hull Speed for Displacement Craft:

Take the waterline length in feet, double it and take the square root. The result will be the maximum hull speed in knots. E.g. Waterline length = 24ft 6in doubled to 49 - the square root is 7 . So maximum hull speed is 7 knots.

Another method reckons maximum hull speed in knots to be 1.6 times the square root of the waterline length in feet which gives a slightly higher figure. Stick to the lower one and you will be less likely to delude yourself about your speed.

Making Landfall:

According to YOSC Sailing Guru - Keith Watts, you should always try to make landfall on Starboard tack as the wind will free as you approach. I have tested this on several occasions and it seems to work - something to do with the wind sheer at the land/sea interface.

Dutchman's Log:

The distance in feet (between two marks on the vessel) times three and divided by five times the number of seconds (of floating object between marks) equals knots of speed. Best to use a small plastic bottle partly filled with water so that it just floats and attached to a small line for retrieval. Throw it forward and wait for it to come alongside the first mark, start stopwatch (or count one, one thousand..two, one thousand..) and turn off watch when object comes alongside second mark. The distance between objects should be as much as possible on any particular boat.

A Few Tips on Sailing Techniques:

More Sound Advice:

When in doubt, stay out!

Give yourself searoom and wait to enter port after making a landfall if night has fallen or entering a strange harbour or port. Come in the daytime when all marks have been identified, try to have the sun behind you to prevent glare on the sea and to identify underwater objects. Don't relax at this point. Most shipwrecks are because of celebrating, sleeping and not keeping watch after the landfall.

Stay out, stay alert, stay sober, stay awake, stay afloat, and stay alive!

Stream an anchor to maximum depth if you're alone and absolutely know you will fall asleep. Then the anchor will hopefully take a bite in the bottom when you drift toward that reef...it just might keep you off the hard bits.

There's nothing dangerous about the sea, it's the hard stuff around the edges that you have to watch!"

Anne Hammick, RYA Ocean Yachtmaster who has crossed the Atlantic eight times, said in "Ocean Cruising on a Budget", "Remember that at no time during a sea crossing is a seaworthy yacht so vulnerable to human error as when the sharp bits are close by, so don't relax the watch system or be tempted to break out the bubbly until you are safely tied up".

The Best Time to Enter and Leave Port:

Tristan Jones recommends leaving and entering port at right angles to the shore and get as much offing (sea room or distance from shore) as possible as soon as possible. Leave on an easterly course in the evening to have the sun at your stern. Enter on a westerly course at sunrise with the sun at your stern. Never enter at night.

RDF Bearings:

Port bearings always decrease going in any direction. Starboard bearings always increase going in any direction. If you're taking an RDF reading off the starboard beam and it keeps decreasing..…then you're really aimed at a station on the port side and you're taking a back bearing off the null.

Single-handed Sailing:

Sailing by oneself for longer than you can easily stay awake is bad seamanship. A proper watch cannot be kept and this alone is reason enough not to do it - also it's illegal! See International Rules for Prevention of Collision At Sea. Captain Bob Griffith on "Awahnee" said, "…but if you contemplate sailing alone, my advice is, don't. A single-handed voyage is often lonely and joyless; you will be without any reserve of ability, strength, or watchfulness. A single-hander must be ready to die, scared or not, each time he lays down his head to sleep. Self-steering rigs keep no lookout."

Some Well-Whipped Ropes Ends:

These are from "The Yachtsman's Weekend Book" by John Irving and Douglas Service. Although it was written in the Thirties when yachts were made of wood, sails of canvas and fittings of brass, the fundamental principles still hold good. Here are just a few snippets that have appealed to me:-
