For any owner of inflatable boats, the issue of reliable anchor fixation is in the first place, especially when fishing in windy weather or on the current. Fist anchor rum It's one of the most popular solutions for fastening the flogging and releasing it instantly if necessary, and unlike simple ducks or mooring stands, it provides a safe and controlled descent, which is critical for lightweight inflatable housings.
The device operates on a spring-drawn mechanism that holds the anchor line between two movable or fixed elements, avoiding overlapping and ensuring that the anchor line is not interlocked. anchor-line It will not slip out of the boat spontaneously even if the boat is vibrating, and a well-chosen model can withstand significant loads, maintaining the integrity of the sides and transom of your vessel.
In this article, we will discuss in detail the design features of various modifications, compare the materials of manufacture and consider the nuances of installation. 90-degree This is a key safety parameter, and how to avoid common mistakes when equipping your vessel. A competent approach to choosing fittings will prolong the life of your boat and make fishing more comfortable.
Design features and principle of operation of the mechanism
The backbone of the device is a body made of durable plastic or metal, and it has a movable cam inside it, and it's spring-loaded, which creates a constant tension that presses the cord against the stationary part of the mechanism, and when you pull the flap, the cam turns, letting the rope pass, but when the tension is relaxed, it instantly blocks its movement in the opposite direction.
Modern models are often equipped with additional protection elements, such as soft tabs or rollers, which minimize friction. Anchor rim block The cord must be smoothly operated so that the anchor is not sampled with excessive effort that could damage the hands or cause a loss of balance in the boat, and the quality of the spring should be given special attention, as it is responsible for the reliability of the anchor.
An important aspect is the geometry of the cable exit. A properly designed mechanism directs the load strictly along the axis of the attachment, eliminating lateral jerks that could damage the board. Some advanced versions have a rapid uncoupling system that allows you to drop the anchor with a single movement of the hand, which is vital in emergency situations on the water.
- 🔩 High-strength polymer housing, resistant to ultraviolet and salt water.
- 🌀 Spring-loaded cam with a return mechanism for automatic fixation.
- 🛡️ Built-in rollers or smooth surfaces to reduce the wear of the anchor cord.
- ⚓ The ability to quickly unlock the cable without complex manipulations.
⚠️ Attention: Never use a rupture block with damaged springs or a cracked body. At the moment of jerking when lifting a heavy anchor, the mechanism can collapse, leading to loss of cargo or injury.
Manufacturing materials: plastic, aluminum or steel
The choice of material directly affects the durability of the fittings and its compatibility with the type of your boat. plasticsIt's a PVC boat that doesn't corrosive, has low weight, and doesn't scratch the sides when touched by accident, and it's ideal for PVC boats because it doesn't oxidize in salt water and it retains its properties when it's at a temperature differential.
Metallic variants made of anodized aluminum or stainless steel have greater strength, but require caution in operation. Aluminum alloys are lightweight and strong enough, but they can oxidize upon contact with other metals. Stainless steel It is the most expensive and reliable option, but its considerable weight can be excessive for light inflatable small class vessels.
When choosing plastic models, you should consider that they often have a metal axis or inserts in areas of high friction, which is a compromise solution that allows you to combine the lightness of the polymer with the strength of the metal, the main thing is that all metal elements have a high-quality corrosion coating, especially if you plan to operate a boat in a marine environment.
Comparative table of materials will help to determine the choice:
| Materials | Weight. | Corrosion resistance | Strength | Price. |
|---|---|---|---|---|
| Engineering plastic | Very low. | High. | Medium | Low. |
| aluminum | Low. | Medium (anodizing required) | High. | Medium |
| Stainless steel | Highly | Very high. | Very high. | High. |
| Silumin | Low. | Low (fragile) | Low. | Low. |
Where and how to properly fasten the poultry on the PVC boat
The installation site plays a crucial role in the efficiency of the anchor system. cleft They're mounted on a transom, slightly above the waterline, or on bow reinforcement, if the boat design involves anchoring from the nose. When you attach it to the transom, it's important to take into account the angle of departure of the tile so that when you sample the anchor, the cable does not rub against the side of the boat or the engine.
For installation on the soft side, special reinforcement platforms or models with a wide base that distributes the load are used. If you install the device on a rigid transom, you need to use stainless screws with press washers, after drilling holes of a smaller diameter. Glue of extra nickels from PVC fabric under the place of attachment will significantly increase the reliability of fixation on inflatable elements.
☑️ Checklist for installation
inflatable tubes are often fitted with a two-part polyurethane glue, the surface of the balloon and the base of the cone are thoroughly cleaned and degreased, and the glue is applied and dried, and a monolithic compound is produced that withstands severe tear stress without damaging the PVC fabric.
⚠️ Attention: When drilling a hard transom, be sure to use a drill with a depth limiter so as not to damage the internal structure of the material or make a through hole in an unintended place.
Choosing an anchor cord and its compatibility with the fry
The effectiveness of the cam mechanism depends on the specifications of the used anchor-failThe best choice is a wicker cord with a diameter of 4 to 6 mm, which has sufficient flexibility to pass through the mechanism, but is not too thin to be easily grasped with wet hands.
The cord material also matters: nylon pulls well and cushions jerks, but absorbs water and sinks. Polypropylene ropes do not absorb moisture and float on the surface, making it easier to find them in case of falling overboard, but they are less resistant to abrasion. Anchor cable must be selected so that its puffiness does not interfere with the free passage through the fixator.
To facilitate the sampling of the anchor from a depth of more than 3 meters, attach a small buoy or foam float to the end of the anchor cord. This will keep the main flounder in a strained state and will not allow it to get tangled at the bottom.
The length of the cord should correspond to the depths at which you plan to fish, with a margin of 10-15 meters. It is recommended to have a vertebral vertebral at the end of the anchor cable, which will prevent the cord from twisting around the axis of the rump block when rolling the boat, this will prolong the life of both the mechanism and the rope.
Common errors in operation and maintenance
One of the most common problems is the periodic lubrication of the mechanism: sand, silt and salt deposits over time clog the moving parts, making the stroke tight or completely blocking the cam. Preventive services involves washing the device with fresh water after each trip to the sea and lubricating it with silicone spray or lithium lubricant.
Another mistake is to try to misuse the ruffle block, such as mooring to heavy objects or towing, specifically designed to hold the vertical load of the anchor, rather than horizontal jerks when the boat is moving. Excessive lateral loads can break plastic latches or deform the hull.
- 🧼 No fresh water washing after use in salt water.
- 🚫 The use of a cord diameter is less than recommended by the manufacturer.
- 🔨 Mechanical damage to the body when hitting the side or stones.
- ❄️ Operation of the mechanism during icing without prior defrosting.
Regularly check the condition of the spring inside the mechanism, if it weakens or rusts, the fixation will become unreliable. In heavy use, the spring or the entire unit should be replaced every 2-3 seasons, even if external damage is not visible.
What if the anchor is stuck dead?
If the anchor is jammed and the usual thrust is not helping, try changing the angle of the boat's approach. Swim to the anchor point from different sides to change the load vector. If that doesn't work, use a webbing or a special buoy system if it was provided in advance. In extreme cases, you can tie the phala to a powerful winch, but act carefully so as not to turn the boat over.
Comparison of popular models and brands
The market has many modifications, from budget Chinese analogues to products of famous brands like MarineMaster or FlagmanBudget models are often made of lesser quality plastic, which can become brittle in the cold. Expensive counterparts use reinforced composites and metal sleeves, providing a margin of safety.
When choosing, pay attention to the availability of quality certificates and warranty period. anchor It should have smooth edges without burrs that could rub an expensive anchor cord, and it is also worth assessing the ease of grip: some models have ergonomic notches for fingers, which makes it easier to control with one hand.
⚠️ Attention: Cheap models labeled "ABS plastic" without a specified grade can collapse at the first serious spurt on the current.
A properly selected and installed cam crum ensures that you do not lose anchor and maintain the integrity of the boat during maneuvers.
In conclusion, there is no universal solution: for small inflatable boats, a simple plastic model is enough, while for heavy PVC catamarans or hard bottom boats, it is better to choose a combined version with metal elements, the main thing is regular monitoring of the condition of the equipment before each outing.
Frequently Asked Questions (FAQ)
Can a cam rum be used to anchor the boat to the nose?
Yes, it is possible, but it requires proper installation: the bow poop should be fixed to a reinforced pad or a special anchored fry bolt so that the load is distributed correctly and does not deform the balloon. Make sure that the angle of the cord escape allows the anchor to fall freely down without touching the side.
What is the best cord diameter for a standard plastic rift?
For most standard models found on sale, the optimal is considered to be a cord with a diameter of 5-6 mm. 4 mm cord can slip or crash too hard into the mechanism, and 8 mm can simply not fit into the hole or jam the cam.
How to prevent the mechanism from freezing in winter?
Use silicone lubricant, which does not thicken in the cold and pushes moisture out. Before storing, be sure to dry the mechanism. If you have already frozen the fry, do not use force - warm it with a hairdryer or warm water, so as not to break the plastic cam.
Do I need to lubricate the spring inside the roe?
Yes, regular lubrication is necessary, but only with special formulations that do not corrode plastic (for example, silicone or Teflon lubricant). Lithium lubricants can be aggressive to certain types of plastic, so read the instructions for a particular product.
