About This Area
Milford Sound's internal waters, from the highway entrance to the open Tasman Sea, are a world-class boat fishing destination for species like blue cod (catch-and-release only), trumpeter, and groper. Launch from Deepwater Basin or join a charter, but note MPI rules: no blue cod take or pots in internal waters, commercial fishing banned, and no-take zones like the Piopiotahi Marine Reserve. Fish & Game NZ emphasizes checking daily weather; swells up to 5 meters can trap boats overnight. This intermediate activity requires boating experience amid stunning waterfalls like Lady Bowen Falls.
Safety Considerations
Fiordland seas build quickly with katabatic winds funneling down valleys, creating hazardous conditions per NZ Coastguard reports. Monitor barometer drops and exit fiord before 2pm. Strong currents near Stirling Falls demand 40hp+ engines for control. Cold water immersion survival time is under 15 minutes; all aboard must wear lifejackets. Fuel up fully at Deepwater Basin; range anxiety kills. Use EPIRB and two-way VHF. Protect against UV with long sleeves; seal colonies nearby can be aggressive if approached.
Essential Gear
Equip your vessel with a Level 5 PFD like Spinlock Deckster, Icom IC-M25 VHF handheld, ACR ResQLink EPIRB, and fish finder like Raymarine Dragonfly. Rig with Penn Battle reels, 50lb leader for tows, and burley pots. Include an anchor with 5:1 scope chain, bilge pump, and emergency rations for 24 hours.
Emergency Tips
Man overboard: throw life ring, mark GPS position, call VHF 16 or 111. Grounded? Stay aboard, signal with flares. Hypothermia protocol: remove wet clothes, huddle for warmth. Milford Sound maritime radio monitors continuously.
