Rappelling, the controlled descent down a rope, is an exhilarating and practical skill used in various activities, from mountaineering and caving to rescue operations and tactical maneuvers. A crucial element of safe rappelling is a reliable harness. While commercially manufactured harnesses are readily available, knowing how to tie a Swiss seat rappel harness is an invaluable skill. It provides a reliable and customizable harness option, especially useful in situations where a manufactured harness is unavailable or unsuitable.
This comprehensive guide will walk you through the process of tying a Swiss seat rappel harness step-by-step, ensuring you understand each stage and the critical safety considerations involved. **However, it’s IMPERATIVE to emphasize that this guide is for informational purposes only. Before attempting to rappel using a Swiss seat harness, you must receive proper instruction from a qualified and certified instructor. Improperly tied or used Swiss seats can lead to serious injury or death.**
**Why Learn to Tie a Swiss Seat?**
* **Emergency Preparedness:** In unexpected situations, you might find yourself needing to rappel without access to your regular equipment. Knowing how to tie a Swiss seat can be a lifesaver.
* **Customization:** A Swiss seat can be adjusted to fit various body sizes and shapes, making it a versatile option when a standard harness doesn’t quite fit.
* **Resourcefulness:** It allows you to rappel even if your primary harness is damaged or lost.
* **Backup System:** Some climbers prefer to use a Swiss seat as a backup to their primary harness, adding an extra layer of security.
**Materials Needed:**
* **Rope:** A strong, dynamic or static rope, typically at least 12-15 feet long (3.5-4.5 meters). The rope diameter should be appropriate for rappelling (typically 9mm-11mm). **Never use a rope that is damaged, frayed, or has a questionable history.**
* **Carabiner (Locking):** A strong, locking carabiner, preferably HMS (pear-shaped) for easier rope management. Ensure the carabiner is rated for climbing and rappelling.
* **Optional: Rappel Device:** While not strictly required for a Swiss seat (you can use a Dulfersitz rappel), a rappel device like an ATC or figure-eight provides better control and reduces rope wear.
**Important Safety Considerations Before You Start:**
* **Rope Condition:** Inspect the rope for any signs of damage, such as cuts, abrasions, or discoloration. If the rope shows any signs of wear, do not use it.
* **Knot Security:** Ensure all knots are tied correctly and securely. Double-check them before putting weight on the harness.
* **Friction:** Be aware that a Swiss seat, especially when used with a Dulfersitz rappel, can generate significant friction and heat. Wear appropriate clothing to protect your skin.
* **Fit:** The harness must fit snugly but not be overly tight. It should allow for freedom of movement without being loose enough to shift during rappelling.
* **Supervision:** Practice tying and using the Swiss seat under the supervision of a qualified instructor before using it in a real-world scenario.
* **Back-up:** Always use a back-up, such as an auto-block on the brake strand of the rope.
**Step-by-Step Guide to Tying a Swiss Seat Rappel Harness:**
**Step 1: Finding the Center of the Rope**
* Lay the rope out on the ground. Find the middle point of the rope. This is crucial for ensuring equal leg loops and a balanced harness.
**Step 2: Creating the Initial Loop (The Girth Hitch Base)**
* Hold the rope at the center point. Drape the rope behind your back, bringing both ends forward over your shoulders. Imagine you’re putting on a very long scarf.
* Bring the two ends of the rope together in front of you, forming a large loop behind you. The loop should hang down below your waist.
* Pass the two ends of the rope *through* the loop behind you. This creates a girth hitch around your waist. Make sure the loop is snug but not too tight.
**Step 3: Forming the Leg Loops**
* Take one end of the rope and pass it down between your legs, from front to back. This creates the first leg loop.
* Repeat the process with the other end of the rope, passing it down between your legs, also from front to back, creating the second leg loop.
* Adjust the length of the leg loops so they are comfortable and fit snugly around your upper thighs. The loops should not be so tight that they restrict circulation, but they should be snug enough to prevent you from slipping out.
**Step 4: Securing the Leg Loops: The Tie-in Point (Critical!)**
* This is the most critical part of tying the Swiss seat. The next step creates the primary tie-in point where you’ll attach your carabiner and rappel device.
* Bring both ends of the rope *up* from between your legs, in front of your waist. The two ends should meet at your sternum (chest bone).
* **Crucially, create a Figure-Eight Follow Through with both strands.** A Figure-Eight Follow Through is created by tying a Figure-Eight knot with one strand, and then threading the other strand back through the knot in reverse. This distributes the load and creates a very secure tie-in point. (See detailed instructions and diagrams below for the Figure-Eight Follow Through).
* Tighten the Figure-Eight Follow Through securely. It should be snug and close to your chest. There should be ample tail left from both ends of the rope (at least 6-8 inches) after tightening. This is crucial for safety; short tails can slip.
**Detailed Instructions: Tying the Figure-Eight Follow Through**
This knot forms the core of your Swiss seat harness. A correctly tied Figure-Eight Follow Through is essential for your safety.
1. **Create the Initial Figure-Eight:** Take one end of the rope and form a loop. Bring the end over the standing part of the rope (the part that isn’t being used to tie the knot) and then back down through the loop. This creates a basic Figure-Eight knot.
2. **Thread the Second Strand (Follow Through):** Take the *other* end of the rope and thread it *backwards* through the Figure-Eight knot you just created. Follow the exact path of the first strand, but in the opposite direction. Carefully trace the path of the first strand with the second strand.
3. **Tighten the Knot:** Once you’ve threaded the second strand completely through the knot, carefully tighten it. Work out any slack in the knot, starting from the center and moving outwards. Ensure the knot is snug and that the two strands are parallel and neatly aligned.
4. **Leave Adequate Tails:** Ensure that both ends of the rope (the tails) extending beyond the knot are sufficiently long (at least 6-8 inches). This is a critical safety measure to prevent the knot from slipping.
**Step 5: Connecting the Carabiner and Rappel Device**
* Clip a locking carabiner through both loops of the Figure-Eight Follow Through. Ensure the carabiner is fully locked.
* Attach your rappel device (ATC, figure-eight, etc.) to the carabiner. Follow the manufacturer’s instructions for your specific device. If you are using a Dulfersitz rappel (without a device), the rope will run directly through the carabiner.
**Step 6: Securing the Tails (Important Redundancy)**
* Take the two tails of the rope that extend from the Figure-Eight Follow Through. Pass each tail through the opposite leg loop.
* Secure the tails with overhand knots (or figure-eight knots) close to the leg loops. This prevents the tails from flapping around and potentially interfering with your rappel. It also adds an extra layer of security by connecting the leg loops to the main tie-in point.
**Step 7: Final Inspection: The Buddy Check**
* Before rappelling, have a partner (or instructor) thoroughly inspect your Swiss seat harness. This is a crucial safety step. The buddy check should include:
* **Knot Security:** Verify that the Figure-Eight Follow Through is tied correctly and tightened securely. Check that the tails are long enough and properly secured.
* **Carabiner Lock:** Confirm that the carabiner is fully locked.
* **Rappel Device Attachment:** Ensure that the rappel device is correctly attached to the carabiner and that the rope is properly threaded through the device.
* **Leg Loop Fit:** Check that the leg loops are snug but not too tight.
* **Overall Fit:** Ensure that the harness fits snugly and allows for freedom of movement.
**Important Considerations for Using a Swiss Seat:**
* **Friction:** Swiss seats, especially when used without a rappel device, generate a lot of friction. Wear gloves to protect your hands and be prepared for a potentially hot rappel.
* **Comfort:** Swiss seats can be uncomfortable, especially on long rappels. Consider adding padding to the leg loops or using a rappel device to reduce friction.
* **Practice:** Practice tying and using the Swiss seat in a safe and controlled environment before using it in a real-world scenario. The more you practice, the more comfortable and confident you will become.
* **Dulfersitz Rappel (Without a Device):** If rappelling with a Dulfersitz, the rope goes directly through the carabiner. Keep your brake hand below your body and use a fireman’s belay (another person holding the brake strand below you) for extra safety. Be EXTREMELY CAREFUL with this technique as it requires significant control and can be dangerous if not performed correctly.
* **Back-up System:** Always use a back-up system, such as an auto-block (Prusik hitch) on the brake strand of the rope. This provides a crucial safety net in case you lose control of the rope.
* **Dynamic Movement:** Be aware the Swiss seat will shift and tighten with dynamic movement. Practice adjusting to this shift in a safe setting before rappelling in a dangerous environment.
**Alternatives to a Swiss Seat:**
While the Swiss seat is a valuable skill, it’s important to be aware of other options:
* **Commercial Harnesses:** The safest and most comfortable option is a commercially manufactured climbing harness. These harnesses are designed specifically for rappelling and climbing and provide excellent support and safety features.
* **Improvised Harnesses:** Other improvised harnesses can be created using webbing or rope, but these are generally less comfortable and less secure than a Swiss seat or commercial harness. Only use these as a last resort and with proper training.
