We arrived at North Minerva Reef and had the anchor down and set around 9:30am NZST Friday. At 9:40am we were swimming off the back of the boat. Water temp 25.4 degrees, very nice after the 18 degrees in the Bay of Islands when we left (not that we were swimming there).
The Minerva Reefs are interesting and it's quite surreal to be anchored there in the middle of the South Pacific Ocean. There are two reefs North and South about 20Nm (37Km) apart and are 320Nm (600km) from Tonga. North Minerva Reef is higher than South and as such offers more protection from the ocean swell. North is almost circular with an entrence on the north west about 200m wide so quite easy to navigate through as long as there isn't a large swell running across the entrance. It is a relatively large lagoon, 3Nm north/south and 2.6Nm east/west (5.5 x 4.8 Km) We were travelling with another boat in the rally, Vivacious, and on their recommendation we anchored in the northern sector was turned out to be a good choice with regards to crayfish (more on that later). Once inside the lagoon you can anchor in most parts of the lagoon but as with all reef systems beware of coral bommies. We anchored in 10m of clear water over sand so no problem seeing the bottom. While we were there, at the peak there would have been about 20 yachts anchored in various parts of the lagoon. The attached photo of the helm station show the reef on the chart plotter.
The depths in this part of the Pacific are generally 2,000 - 4,000m. The reefs have steep walls and sit on an underwater platform about 500 - 800m deep. These must be old reefs as the top of the reefs are rock and sand unlike the soft coral reefs in Qld. There are corals on the sides of the reef but at low tide you can safely walk on the reef without damaging the reef system or yourself. Consequently reef walking is a popular activity at low tide.
The relative calm of the lagoon was an opportunity to do some essential repairs. Definition: "Cruising - Doing maintenance in exotic locations". Fixed the mainsail traveller, we can use the mainsail again. Fixed a newly found problem on the boom vang, a major problem averted. Adjusted both prop shaft seals. Prepared meals for onward passage tp Tonga. A load of washing done, yes domestic chores still have to be done no matter how exotic the location.
But it wasn't all work. There was time to socialise, shared bubbles Friday evening with Russ & Jane off Vivacious celebrating the passage to Minerva. It was Jane's first offshore passage so a second bottle was called for. Coffees and chats with fellow cruisers. Fishing, caught a nice spotted cheek emperor for dinner Saturday. Catching crayfish.
Crayfish are nocturnal so there are 2 main ways to catch them. One is in daylight hours, dive down the outside of the reef wall and look for them in the crevices, grab them with a gloved hand and pull them out. Sounds easy but the reality is on the outside wall of the reef you can get tumbled around in the swell, the crayfish are surprisingly strong and can really hold on to the rock wall of the crevice with their 8 legs and that powerfull tail is flapping about, all the time you are holding your breathe. The other way is at night, walking on the reef around low tide with a powerfull torch or lantern. When caught in the bright light, the crayfish stay still looking at the light with their eyes glowing bright orange. You can grab them with a gloved hand or use a hand spear to pin them to the bottom while you get hold on them. This takes place in about 20 - 30 cm of water. No prizes for guessing which method I used. Sunday night I went with friends, Lars and Maria off Alexandra around 8pm. Unfortunately, Lars and Maria's torches weren't powerfull enough to immobilise the crayfish but mine certainly was. I lost a couple initially caught off guard by how strong the tail is and how tight you have to hold them to get them up and into the bag. Once I had mastered the technique I managed to bag 5 crayfish, 2 of which we shared with Lars & Maria. I removed the tails and cut them down the middle and Ann grilled them in the oven. Delicious with salad in a wrap for lunch Monday and today.
We left Minerva yesterday, Monday, around 4:30pm and ETA in Pangai, Tonga is late Thursday morning. We were motoring in light winds overnight but have been sailing since 7am this morning. As usual we are timing our arrive and passage through the reef systems for good morning light after 9am. As such we a running the boat with reduced sail area to maintain a speed for that arrival.
