Why is anchoring on the flow a separate science?

Parking on the PVC boat's current is not just about anchoring and forgetting, but even a small stream of water creates a load that can move the boat, twist the shaft, or even break the mounts, unlike standing water, where there is enough minimal weight, over the course of the boat. The anchor must hold the boat against dynamic pressure.The technique of throwing and fixing the fag requires a special approach.

Mistakes here are not only fraught with drift. For example, if the anchor crawls down the bottom, the tile can wrap around the propeller of the outboard motor, which will lead to the failure of the gearbox. And if the bottom is rocky, the wrong anchor risks getting stuck or breaking the PVC tank of the boat. anchor quickly, reliably and effortlessly.

Choice of anchor: which type reliably keeps the PVC boat on the flow?

For PVC boats on the current is not so much the weight of the anchor as its construction and method of clinging to the groundLight mushroom anchors (popular among anglers) often slide on sluggish or sandy bottoms, and heavy Admiralty anchors can damage cylinders when jerked.

  • πŸ† Danforth anchor Its legs are buried in the ground, providing a holding force 10 to 15 times its own weight, suitable for sand, silt and small pebbles.
  • βš“ Bruce's anchor (peck-shaped) - versatile for rocky bottom, but requires accurate throw. Weight: 1.5-3 kg for boats up to 4.5 m.
  • πŸͺ¨ Folding cat anchor It's compact, but it's worse in strong currents, and it's also suitable for temporary parking.

The weight of the anchor is calculated by the formula: 1 kg for every 30 cm of boat length +20 percent of the current reserve. Frigate 360. (3.6 m) need anchor 1.5-2 kg (for weak current) or 2.5–3 kg (for quick flow).

⚠️ Attention: Do not use homemade scrap metal anchors (such as weights or rail trimmings) that do not sink into the ground and can damage the boat when snatching.
Type of soil Recommended anchor Weight (for boats 3.5-4 m) Features
Sandy bottom Danforth, Bruce. 2-3 kg The legs should be deepened by at least 10-15 cm
Ilisty bottom Danforth with wide paws 2.5–3.5 kg Additional use of stern pulling
Rocky bottom Bruce, cat anchor. 3-4 kg Risk of hook - toss at an angle of 45Β° to the current
Grass bottom Danforth with sharp paws 2-3 kg Before throwing "paddle" the bottom

Fail length: why does "3 times the depth" not work on the current?

The classic rule phala length = 3 Γ— depth This is true for standing water. During this time, this ratio increases to 5–7and with a strong flow, up to 8–10Why not?

Short-fault anchor not fall to the bottom at the right angleIt's almost vertical, and its holding force drops by a factor of 2-3, and it's also constantly rushing forward, and the thaw has to cushion the thrusts, otherwise the balloon's mounts will break.

Formula for flow: Fala length (m) = Depth (m) Γ— 5 + 2 m (stock per knot)

Example: at a depth of 4 m you need a fall 22-24 m (for flow 1-2 m/s).

πŸ’‘

Use a phala with tags through each meter (for example, colored tape) to quickly navigate how deep you stand without pulling the entire cable.

  • πŸ”„ Synthetic falla (polypropylene, nylon) stretches by 10-15%, softening the jerks.
  • β›“ Chain segment (1-2 m in front of the anchor) weights the structure and does not allow the faucet to rub on the bottom.
  • 🧲 Carbine with vertebrate prevents the twirling of the fala when changing the direction of the flow.

Anchor throw technique: how to avoid drag and hooks?

The wrong throw is the main reason why the anchor doesn't hold. not just throw, but "lay" to the bottom And then you have the flow direction.

  1. The counter-tide approach. Slow down the boat with your motor or paddles so that it almost stops relative to the water.
  2. Throw at an angle of 30 to 45 degrees. Don't throw the anchor down, it can lie down on its side, optimally, a little upstream.
  3. Smooth thrust of the fala. Do not drop the entire cable at once - release it as the boat drifts so that the anchor lies flat.
  4. Fixing on tension. When the tile is pulled, let the boat move back a little so that the anchor sinks.

Make sure the fag is not twisted |

Check the mounting of the faΓ§ade to the boat (node "average" or carbine)|

Evaluate the direction and speed of the current (throw up the stream)|

Prepare for aft delay (if the current is strong)

-->

If the bottom is uneven (stones, snags), throw anchor with feed-off - an additional cable attached to the back of the boat, which will prevent the boat from turning to the current and reduce the load on the main crumbling.

⚠️ Attention: Never anchor from the bow of a boat at full speed. A sudden stop can tear the cylinder mounts or knock passengers off their feet.

What if the boat is even with an anchor?

If the boat is drifting despite anchor, the problem lies in one of three factors:

  1. Inadequate weight of anchor (especially on a sluggish bottom).
  2. Too short a phala (The anchor does not lie horizontally).
  3. Wrong direction of throw (The anchor is drawn, not deepened).

Decisions:

  • βž• Increase the length of the phala If the depth is 3 m, release the 25-30 m of the fail.
  • πŸ”„ Add the aft delay - A second anchor or a load on the cable from the stern, which stabilizes the boat as it flows.
  • πŸ‹οΈ Weight down anchor chain (1-2 m) or additional load (for example, a bag with stones).

How to make a feed delay from improvised means?

Take a second anchor (or a load of 3-5 kg) and a cable 5-10 m long. Secure it on the stern of the boat so that it goes at an angle of 45 Β° to the main phala. This will create a stretch that will prevent the boat from turning across the current. For a temporary solution, you can even use a full canister of water (5-10 liters) as a cargo.

If the bottom is sluggish, try the technique of "anchor-plough": after the throw, let the boat move back 5-10 m so that the anchor "ploughs" the ground and sinks.

Typical mistakes: What will speed up the drift or damage the boat?

Even experienced water-engineers sometimes make mistakes that negate all efforts. 5 critical errors and their consequences:

  • 🚫 Use one anchor on a strong current.
    β†’ The boat turns on board, sailing increases, a coup is possible.
  • 🚫 Fixing the fax to the nose loop without depreciation.
    β†’ The current jerks tear the loops of cylinders or deform the transom board.
  • 🚫 Anchor throw from the side (not from the nose).
    β†’ The boat can capsize in a sharp jerk.
  • 🚫 Ignoring the aft delay.
    β†’ At the sluggish bottom, the boat will "walk" in a circle.
  • 🚫 Storage of the fag in the coil (not the cove).
    β†’ When unrolling, nodes are formed that weaken the tension.

Another common problem is that phalaTo avoid this, use it. cockpit between the thack and the anchor, and periodically check the cable for hinges.

πŸ’‘

For more than 1.5 m/s, always use two anchors: the main one from the nose and the aft bracket, which reduces the load on the cylinders and prevents the boat from turning.

How to get off the anchor quickly without any problems?

Incorrect removal from the anchor can lead to its loss or damage to the boat.

  1. Rinse the thunder until tension, but do not pull sharply - check if the anchor is caught.
  2. Get to the anchor against the currentSo the falter is weakened and can be pulled out without effort.
  3. If the anchor is stuckTry to rock the boat back and forth, relaxing the tension.
  4. Clean the anchor of dirt/grass before stacking so that it does not cling to the cylinders.

If the anchor is stuck between the rocks, use the "shoot to the side" technique: sail at an angle of 30-45 degrees and sharply pull the falt to the side, often helping to move the anchor from the dead point.

⚠️ Attention: Never wrap the phala on your arm when you pull -- it can amputate your fingers when you jerk it, use gloves and wind the cable on a winch or a switch.

FAQ: Answers to frequent questions

Can I use one anchor for two boats?

Theoretically, yes, but only if the boats are close to the river and connected by an extra cable, but in practice, it's risky: if you change the direction of the flow, one boat can turn around and collide with the other, and you'd better use separate anchors.

Which knot is better for attaching the faΓ§ade to the boat?

Best options:

  • The squat-knot It is easy to untie even after a heavy load.
  • Fishing bayonet - reliable, but requires skill to untie.
  • Carbine with vertebrate The fastest and safest way.

Do not use a β€œbaby knot” or β€œsimple bayonet” – they can untie when jerking.

What if the anchor is caught on the snag?

Don't pull the phala by force, it can break the mounts.

  1. Swim to the side and pull the phalo at an angle.
  2. Use a second anchor to turn the boat around and change the direction of tension.
  3. If nothing helps, cut the phala (but only in extreme cases).

To prevent hooks, drop anchor in areas with a clean bottom (check with a sonar or pole).

Do you need to anchor if you catch fish with the current?

Yes, even if you're constantly moving, the current may suddenly become stronger (for example, due to the opening of the locks or the wind), and the boat will blow. lightweight anchor (1-1.5 kg) with a quick-removal mount, so that it can be quickly transferred.

How to keep the anchor and the falters so that they do not rust and do not get confused?

Storage tips:

  • After use, wash the anchor and fala with fresh water.
  • Then, dry the rope in a straightened form (not in the sling!).
  • Keep the anchor in a bag of silica gel (moisture absorber).
  • Lubricate the metal parts WD-40 Or solidol.
