Oh nooo, cruel, cruel ocean. Now you have a mast, now you don’t. Bon courage Sam!
Only about one and a half month to the start of the Vendee Globe. Really looking forward to it. A surprising number of names from the edition of 4 years ago will be present again in this edition, so it must be good!
I will be following Samantha Davies. I think she’s a real heroin sailing an 18 meter boat around the world single handed and non-stop and enjoying it as well!
The electric drive system is running! It’s a bit noisier than I had hoped for and the engine doesn’t run entirely smoothly yet. However, Wahine runs at approximately 5 knots at full throttle, which is what I had hoped for. 3 to 3.5 knots can be achieved at 20 to 30 amps, which can be maintained several hours. I haven’t drained the batteries yet and would rather not, so not sure how many, but graphs from the battery manufacturer suggest 6 to 7 hours at 25 amps should be obtainable. Reverse is very poor due to the folding propeller, which was to be expected. A better folding propeller is high on my wishlist now, but expensive.
Next up is connecting more of the controller’s wiring like the engine temp sensor, operation LED’s, improved control box and hooking the controller up to the PC for diagnostics and settings. I’ll also attempt to improve the engine and saildrive alignment en suspension to try and reduce noise.
The whole system now consists of:
Wahine’s first trip to a friend’s wedding on Schiermonnikoog was a great success. After starting with very little wind, the weather was absolutely perfect. The last part of the channel towards the harbour of Schiermonnikoog is rather shallow, so friend Jan came along as ballast to heel Wahine over sufficiently to reduce her normal draft of 1.55m.
After about two years of occasional shore based work, Wahine has finally been launched. I was ecstatically happy!
After numerous adventures with the keel construction –the keel is made of very poor quality cast iron– , it was finally reattached to the boat yesterday. 8 new keel bolts are in place to make sure it won’t fall off. The bending moment at the keel root when the boat is heeling is enormous –an estimated 4kNm at 90 degrees heel–. I am still not entirely sure that both the bolts and the wooden frames will be able to support it. Some glass/epoxy reinforcements planned for next spring should make me feel a little more comfortable yet.
Motor controller, battery charger and DC-DC converter arrived from china today.
Got the sail drive installed and created an engine seat.
