To wear:
Wearing or veering is the opposite of tacking. In a heavy sea when there is danger of a boat miss-staying it is better to wear. To wear, get your sheet in flat, then put the helm up slowly and as she pays-off, ease the sheet gradually. To wear a yawl ease off the mizzen, keep the mainsail flat, and haul the jib a-weather. In a centerboard boat haul up the board. In a catboat if she refuse to wear drop the peak.
To anchor:
The one prime rule of anchoring is never to let go the anchor until the boat has stopped going ahead and is beginning to go sternwards. In this way you prevent the anchor being turned over, and brought foul of the hawser. Always give an anchor plenty of line or scope as it is called. Six times the depth of water is sufficient under ordinary conditions. In bad weather give all you can spare.
To get underway:
If at anchor before making sail heave in short on your hawser or chain, but be careful not to take in enough to trip the hook, then cast loose and hoist the sail, when ready heave in and break the anchor out of the bottom.
To cast:
To cast a vessel is to turn her head from an anchorage or mooring so as to make her go off on a chosen tack. This is sometimes necessary when anchored between other vessels or close to shore. Supposing it is necessary in order to clear to take the port tack: Haul your mainsail over to starboard, putting your helm the same way. This wall cause her to make a sternboard and her bow will fall off to port. A surer way if at a mooring is to pass a light line to the buoy; carry this aft outside of the rigging to the starboard quarter, then let go the mooring warp and haul in on the spring line. This will cause her head to pay off to port; when on the course let go the spring. To cast her to starboard reverse these proceedings.
