Introductory guide to rocky‑shore fishing safety: perfect guide to life jackets, shoes, and escape routes

01Life Jacket – Why It’s Essential

Life jackets provide buoyancy by increasing surface area when immersed. The Korea Coast Guard’s ‘NEC (Durability·Buoyancy) 4.0 ton’ rating is sufficient to keep an average adult (70 kg) above water for more than 1.5 m.

Jackets below this rating dramatically increase the risk of sinking in rapid currents or heavy waves.

• Buoyancy ≥ 4.0 ton → Maintains a 1.5 m surface for a 70 kg adult
• Jacket weight ≤ 1.2 kg → Minimizes fatigue during prolonged wear
• Reflective strips ≥ 2 → Ensures visibility at night or in fog

When selecting, prioritize ‘Adjustable’ straps and a ‘Full‑body’ style. Adjustable straps help maintain buoyancy as body shape changes, and a full‑body cover prevents rapid weight gain when soaked.

Before wearing, conduct a buoyancy test (float in water) to verify that actual buoyancy matches the stated value.

02Anti‑slip Footwear – The First Line of Defense for Your Feet

Rocky shores become extremely slippery with waves and currents. The Ministry of Oceans and Fisheries’ ‘Shore A 70‑80’ hardness standard offers over 15 % more friction than typical rock surfaces (≈ Shore A 60).

At this hardness, the risk of slipping is greatly reduced even on rainy or highly tidal days.

• Sole material: rubber·synthetic rubber (hardness Shore A 70‑80)
• Ankle secure: Velcro or laced (tightening force ≥ 30 N)
• Waterproofing: ≥ 5 mm waterproof membrane applied

When choosing shoes, evaluate both ‘ankle retention’ and ‘sole friction surface’. Insufficient ankle retention can cause the foot to be swept into the water, and a weak friction surface can lead to slipping on rocks and increased injury risk.

Before actual use, submerge and perform a slip test to confirm at least a 30 % increase in friction.

03Escape Route Design – Secure a Safe Zone Within 30 m in Emergencies

If you fall into the water, the most critical factor alongside a floating jacket is the ‘escape route’. According to Korea Coast Guard safety rules, even in worst‑case scenarios a safe exit point (e.g., beach, buoy, vessel) within 30 m reduces rescue time to under 2 minutes.

This distance is calculated based on an average rescue vessel speed of ≈ 10 km/h (≈ 2.8 m/s).

• Maximum escape distance: ≤ 30 m
• Safety point types: beach·buoy·boat·rescue vessel
• Route marking: portable light·reflective tape

When designing the route, consider ‘visibility’ and ‘terrain obstacles’. Use lighting (LED lights) and reflective tape to keep the route clear at night, and place terrain obstacles (rocks, currents) at least 2 m apart.

Additionally, install a ‘emergency call zone’ (portable whistle·satellite messenger) along each segment to enable immediate rescue requests.
