Sighting Drills That Keep You Swimming Straight in Open Water

Swimming in a perfectly straight line sounds simple — until waves, currents, and the absence of lane ropes turn a 1,500-meter swim into 1,800 meters of wasted effort. Every unnecessary meter costs energy, time, and mental focus. The solution is sighting: the skill of lifting your eyes to check direction without destroying your stroke rhythm. The good news is that sighting is entirely trainable, and the best place to start is in the pool.

 

🎯 Why Sighting Is the Most Underrated Open Water Skill

 

Most swimmers spend months refining their freestyle technique, building endurance, and perfecting flip turns — then jump into open water and immediately swim off course. Research from sports science institutions confirms that open water racing demands sustained effort at 80–90% of VO2max. Swimming even 10% extra distance at that intensity can mean the difference between finishing strong and struggling through the final stretch.

 

Efficient sighting does three things simultaneously. First, it keeps the total distance swum as close to the actual course distance as possible. Second, it preserves body position and minimizes drag. Third, it maintains stroke rhythm so that the swimmer doesn't lose momentum every time they look up. Achieving all three requires deliberate practice — not just occasional glances during open water sessions.

 

🐊 Drill 1: Crocodile Eyes — The Gold Standard of Efficient Sighting

 

The crocodile eyes technique is widely considered the most energy-efficient sighting method among open water coaches and experienced ocean swimmers. The concept is exactly what it sounds like: lift only the eyes above the water surface, just as a crocodile exposes the minimum amount of its head while scanning for prey.

 

How to practice it:

⚡ Swim normal freestyle down the pool. At the midpoint of each length, press your chest slightly forward and lift your head just enough so your goggles — and nothing more — break the surface.

⚡ Keep your mouth and nose submerged. This is critical. The moment your mouth clears the water, you have lifted too high, and your hips will drop.

⚡ Hold the sighting position for less than one second, then immediately return your face to the water and continue your stroke.

⚡ Practice this 2 times per 25-meter length for 4 × 100m as part of your warm-up or cool-down.

 

The key insight with crocodile eyes is that the lower the head stays, the less the hips sink. Every extra centimeter of head elevation creates exponentially more frontal drag. In calm water conditions, crocodile eyes provides all the visual information needed to maintain course direction while barely disrupting the stroke cycle.

 

🏊 Drill 2: Polo Drill (Water Polo Freestyle) — Power Sighting for Rough Conditions

 

When waves get bigger and crocodile eyes no longer gives a clear line of sight, the polo drill builds the strength and coordination needed for full head-up sighting. Water polo players swim entire matches with their heads above water — this drill borrows that capacity for open water purposes.

 

How to practice it:

⚡ Swim freestyle with your head fully above water, eyes looking forward. Your chin should sit at or just above the surface.

⚡ Maintain a strong flutter kick — the kick must increase in intensity to compensate for the elevated head position and keep the hips from sinking.

⚡ Focus on a fixed point at the end of the pool (a clock, a sign, a lane marker on the far wall) and swim directly toward it.

⚡ Start with 25-meter repeats. Build to 50 meters as strength improves.

 

The polo drill is deliberately exhausting. That is the point. It strengthens the upper back, builds kick endurance, and trains the neuromuscular pattern of swimming with an elevated eye line. In race conditions with choppy water, a swimmer who has done regular polo work can lift their head comfortably for one or two strokes, get a clear sighting, and return to normal position without fatigue accumulating rapidly.

 

🔄 Drill 3: Head Up / Head Down — Building the Sighting Rhythm

 

This drill teaches the transition between sighting and normal swimming — the exact movement pattern used in open water races. It develops the ability to sight quickly and return to an efficient body position without hesitation.

 

How to practice it:

⚡ Swim 4 strokes with your head up in polo position, eyes locked on a target ahead.

⚡ Swim 4 strokes with your head down in normal freestyle position, face in the water, exhaling steadily.

⚡ Repeat this alternating pattern for the entire length.

⚡ As the drill becomes comfortable, reduce the head-up phase to 2 strokes while keeping the head-down phase at 4–6 strokes. This more closely mimics real open water sighting ratios.

 

The progression matters here. Starting with equal 4-and-4 builds confidence and body awareness. Gradually reducing the sighting strokes teaches efficiency — the goal in open water is to gather directional information in the fewest possible strokes with the head elevated.

 

🙈 Drill 4: Swim Blind — Discover Your Natural Drift

 

This is arguably the most revealing drill in open water preparation. Every swimmer has a natural drift — a tendency to veer left or right when swimming without visual cues. Most swimmers do not know which direction they drift, or how severely. The swim blind drill exposes this hidden asymmetry.

 

How to practice it:

⚡ Choose an empty lane (safety first — make sure there is no risk of collision).

⚡ Close your eyes and swim normal freestyle for 25 meters.

⚡ When you reach the wall (or a lane rope), open your eyes and observe where you ended up relative to where you started.

⚡ Repeat 4–6 times and note the consistent pattern.

 

Experienced open water swimmers in online communities consistently report that simply knowing their drift direction solves about half of their navigation problems. If a swimmer knows they naturally veer left, they can consciously aim slightly right during open water swims, or increase sighting frequency when conditions make drift worse. This self-knowledge is foundational — all other sighting techniques work better once a swimmer understands their own asymmetry.

 

🦈 Drill 5: Tarzan Swim — Full-Length Head-Up Endurance

 

Named after the classic movie character's swimming style, the Tarzan swim takes the polo drill concept and extends it to build serious endurance in the head-up position. This drill is not about technique refinement — it is about building the physical capacity to sight comfortably even when fatigued late in a race.

 

How to practice it:

⚡ Swim an entire 50 or 100 meters with your head above water, maintaining a strong forward gaze.

⚡ Focus on keeping the kick powerful and consistent throughout.

⚡ Maintain a high elbow catch even with the altered head position.

⚡ Use this sparingly — once or twice per week in sets of 4 × 50m with generous rest intervals.

 

The Tarzan swim builds the back arch strength, sustained kick power, and shoulder endurance that make brief sighting efforts feel effortless by comparison. Think of it as the heavy lifting that makes the actual race-day sighting feel light.

 

⚖️ Drill 6: 3 Right / 3 Left / 6 Regular — Bilateral Sighting Balance

 

Many swimmers breathe exclusively to one side, which creates a subtle but persistent directional bias. This drill forces balanced body rotation and sighting capability from both sides.

 

How to practice it:

⚡ Swim 3 strokes breathing to the right side.

⚡ Swim 3 strokes breathing to the left side.

⚡ Swim 6 strokes with normal bilateral breathing (every 3 strokes).

⚡ Repeat this 3R/3L/6 pattern continuously for 200–400 meters.

 

This drill corrects the one-sided rotation habit that is one of the primary causes of veering off course. When a swimmer can breathe and sight comfortably from either side, they gain the flexibility to adapt to wave direction, sun glare, and competitor positioning during open water swims.

 

🔑 The Critical Rule: Separate Sighting from Breathing

 

This is the single most important principle in open water sighting, and it is the mistake most swimmers make when they first leave the pool. Sighting and breathing must be two distinct actions.

 

The correct sequence:

1️⃣ Lift eyes forward (mouth stays in water) — this is the sighting phase.

2️⃣ Rotate head to the side to breathe — this is the breathing phase.

3️⃣ Return face to water and continue swimming.

 

The common mistake: Lifting the head forward AND breathing at the same time. This forces the head much higher out of the water, which causes the hips and legs to plunge downward, creating massive drag and breaking stroke rhythm. Over a 1,500-meter swim, this combined movement can add minutes to a finishing time.

 

Practice this separation in the pool until it becomes automatic. During crocodile eyes or polo drills, consciously keep the mouth submerged during the forward look, then rotate to breathe as a separate movement on the next stroke.

 

📋 The 2-3 Sight System: A Race-Day Protocol

 

U.S. Masters Swimming recommends a structured sighting pattern that many elite open water swimmers use as their default navigation system. Rather than sighting once every few seconds, the protocol calls for 2–3 consecutive sightings followed by 20–30 seconds of head-down swimming.

 

How the system works:

👁️ Sight 1 — Position check: Where am I relative to the target?

👁️ Sight 2 — Angle adjustment: Am I heading directly at the target, or do I need to correct?

👁️ Sight 3 — Direction verification: Confirm the correction is taking effect.

Then swim head-down for 20–30 seconds before repeating.

 

This clustered approach is more efficient than evenly spaced single sightings because it provides a complete navigational picture in one burst, then allows a long stretch of uninterrupted, efficient swimming. Online triathlon and open water swimming communities consistently confirm that this pattern feels more natural and produces straighter lines than the commonly taught "sight every 6 strokes" approach.

 

🌊 Adapting Sighting to Conditions

 

One size does not fit all in open water. The sighting technique and frequency should change based on conditions:

 

🔹 Calm water: Crocodile eyes every 20–30 seconds. Minimal energy cost, maximum efficiency. Eyes barely break the surface.

🔹 Light chop: Crocodile eyes with occasional polo lifts. Raise the head to nose level when small waves block the view at eye level.

🔹 Rough water with significant waves: Full polo sighting, timed to coincide with the crest of a wave. Sighting from the top of a wave provides the highest vantage point and the clearest view of distant landmarks.

🔹 Strong currents: Increase sighting frequency. Australian ocean swimming coaches recommend sighting every 4 strokes in strong current zones and every 8 strokes in weaker current zones. This dynamic adjustment prevents large deviations without wasting energy on excessive sighting in calm sections.

 

🏗️ Building Sighting into Weekly Training

 

Sighting drills do not require a dedicated workout. The most effective approach is to integrate them into existing pool sessions using a simple framework:

 

📌 Every workout: Include 2 crocodile eyes sightings per length during warm-up (200–400m total). This takes zero extra time and builds the habit automatically.

📌 Every 2nd or 3rd workout: Add a dedicated sighting set — 4 × 100m alternating between head-up/head-down drill or 3R/3L/6 regular pattern. Total addition: 400 meters and about 8 minutes.

📌 Once per week: Include one Tarzan swim or polo set (4 × 50m) for strength building.

📌 Once per week: Run the swim blind drill (4–6 × 25m) to monitor drift patterns and track improvement.

 

Within 2–3 weeks of consistent practice, most swimmers report that sighting begins to feel natural rather than disruptive. The key is frequency and consistency — short, regular practice beats occasional long sighting sessions.

 

💡 Bonus: Catch-Up Drill Meets Sighting

 

One advanced strategy that experienced coaches recommend is combining the catch-up drill with sighting practice. In the catch-up drill, one hand waits at the front while the other completes a full stroke cycle. This creates an extended glide phase — and that glide phase is the perfect window for a quick crocodile eyes sight.

 

By timing the sight during the glide, the swimmer maintains forward momentum while getting directional information. This combination teaches a crucial race-day skill: sighting without slowing down. Practice this as 4 × 100m catch-up freestyle with one sight per length during the glide phase.

 

⚠️ Common Mistakes to Avoid

 

🚫 Lifting the head too high: If the chin clears the water during a sighting in calm conditions, the head is too high. Practice crocodile eyes until the minimum-lift habit is ingrained.

🚫 Breathing and sighting simultaneously: This is the most common error and the most damaging to body position. Always separate these two actions.

🚫 Skipping pool practice: Triathlon and open water communities consistently warn that attempting to sight in open water without pool preparation multiplies energy expenditure by 2–3 times. The pool is where technique gets refined; the open water is where it gets applied.

🚫 Sighting at a fixed interval regardless of conditions: Rigid "every 6 strokes" rules waste energy in calm water and leave swimmers off course in rough water. Learn to adjust frequency dynamically based on conditions.

🚫 Ignoring natural drift: Without doing the swim blind drill, swimmers remain unaware of their built-in directional bias. This hidden asymmetry silently adds meters to every open water swim.

 

✅ Putting It All Together

 

Sighting is not a talent — it is a trainable skill that improves predictably with structured practice. Start with the swim blind drill to understand personal drift tendencies. Build the crocodile eyes habit during every warm-up. Add polo and head-up/head-down drills for strength and transition smoothness. Use the 3R/3L/6 pattern to eliminate bilateral asymmetry. Then, when race day arrives, deploy the 2-3 sight system and adjust technique based on wave conditions.

 

The swimmers who swim the straightest in open water are not the ones with the best eyesight — they are the ones who practiced sighting as seriously as they practiced their stroke. Every meter saved is energy preserved for the finish. Make sighting a non-negotiable part of training, and the open water will feel far less chaotic and far more like home.
