Bullets continue. Rainy/showery morning. Girls replaced the lee-helm self-steering lines with thicker lines which should grip in the cleats better. They helped me fit the battery box we bought back in Walvis Bay, to protect the engine start/windlass battery.
Things we learned on Hokule’a. The captain, Bruce Blankenfeld cook and navigator don’t do watches. Watch consists of 3 crew on a 4 hour watch system with 12 crew on boat. Changing crew in Natal, Brazil. Hokule’a’s research revealed Brazil not a preferred destination due to security risks, particularly for female members of the crew and they planned to stay only one night to effect the change of crew.
Hokule’a use ¼” dacron/polyester 3-ply lashings instead of the 8mm polyester braid used on the Wharrams. According to Bruce, a New Zealand built canoe sailed to Hawaii and had used 8mm braid as well. The crew had reported constant hassles with lashings becoming loose on the trip. Bruce said they replaced them with 6mm 3-ply and solved the problem. The advantage, according to Bruce, is that the thinner line can have all the stretch pulled out of it when applying the lashing. The lashings on Hokule’a are set like concrete. Bruce says they get 20,000 miles or something like that, before re-lashing. They have had the old lashing ropes tested at the end of their lifetime and found very little loss of strength. He suggested we use a diamond style lashing on the fore and aft netting beam hull attachments. But we didn’t have time to learn it! Trip to Hawaii anyone?
I described the lateral forces on our lashings and the hull slippage we were experience. Bruce immediately pointed out their lateral thru’ hull lashings, which, he said, are used on all Hawaiian canoes.
About 75’ long, 16,000 lbs unladen, 25,000 lbs laden?. About 11 beams, each one atop a watertight bulkhead. i.e. about 6’6” between beams? = bunk length for the crew members sleeping between the beams on deck.
The decks used to be bamboo but that was too hard on the feet. Now ~30mm planks with non-skid paint. Bruce noted the tightly lashed deck planks also added rigidity to the framework. Only one Micronesian man, “Mau” Piailug from the Carolinian island of Satawal, was willing to tell the story of the lashings, because no-one else in the village left and at least the Hawaiian bro’s would be able to keep it alive for later.
Hokule’a hulls are now all foam and glass. The old wooden hulls began to rot so they used the best one as a mould. The hulls are completely given over to storage (aka what we have been thinking).
Skipper of the Gershwin (Hokule’a escort vessel), and Bruce met James Wharram and 3 wives in 1994 in Hawaii. They described James’ 63’ Spirit of Gaia as beautiful.
