So. Who has and hasn't been to Sea?

Well a Ketch built out of composites probably isn’t big enough for that to be a problem. A cruise ship on the other hand…

Nor do cruise ships. Ballast is used on cargo vessels sailing "in ballast" which means they are sailing without cargo or with cargo that does not displace enough water for the vessel to maintain stability afloat.

Am I permitted to add the following?

But it does "hog, sag," lurch, drop and climb when it hits turbulance and it's wings are very plyable and the stresses it is subject to on landing are tremendous. And yes, you did ask the question; "what the hell do I know?" and maybe, yes, all those years at sea may have been wasted, only you can be the judge of that.

By all means, totally wasted.

The point of my ballast remark was; Lightweight composites are not necessary a better material for ship building. Aircraft need to be as light as possible to take off. Ships on the other hand require a bit of weight, ideally low down to keep the thing stable. Buildings ships out of lightweight materials no doubt helps fuel efficiency, but without added ballast a ship with its hull made out of steal will be much safer than the same ship made out of composites as its centre of gravity will be lower.


On the other point that desertswo brought up, hogging and sagging; I'm certainly no expert when it comes to material sciences, but steal is certainly malleable. Whilst composites are no doubt much stronger, I believe they are also much more brittle. Thus, my understanding of it is that hulls made of steal are more susceptible to hogging and sagging, but steal can be bent back into shape. If there is a problem with composites, it could leave a tear or gash which would not only be hard to fix being under the water line, but also potentially catastrophic.

Back to marine architecture. Modern cruise ships draw about 25/30ft of water and are designed to be very sea kindly underway, stabilized and isopod driven also contribute to their sea-kindliness. I do believe that neither the Finnish, German, French or Italian governments would allow anything but sea worthy ships to be built in their yards and the shipowners would not accept anything other than sea-kindly vessels for their clients. I have yet to read of a sea disaster on a cruise ship which has been launched in the past thirty years.

Once again, all modern cruise ship hulls are built of steel, it is the exterior superstructure which is built of aluminum and the interiors of the ship with pre-fabricated petro-chemical products. Traditional materials, like wood, copper, brass, ceramics and heavy glass would, assuredly, make a cruise ship top heavy.

Misunderstanding, understood.

Expecting to be at the anchorage by early afternoon. Great sail for most of the voyage. Under high pressure with a perfect day, weatherwise, ahead.

Your post put me in mind of something; the three times I've been below the equator (Nuku'alofa, Tonga,; Perth/Freemantle, Australia; and Manta, Ecuador) I was struck by the simple fact that the stars, which as you know are ever so much clearer and brighter at sea, are not "MY" stars. I don't know why, but I found the experience a bit unnerving. Probably too harsh a term, but it was an odd feeling just the same; like "We're not in Kansas anymore, Toto!"

In any event, just to throw a bit of whimsy into the discussion, and in honor of your voyage in the southern latitudes, I give you one of my favorite songs from my salad days as a young naval officer about the sea as metaphor for living an eventful life.

I am always awe struck by the southern night sky. As for them "not being my sky", on the contrary, I claim all the stars as my own.

I would like to continue on to Fatu Hiva but, alas, I think I will be to busy.

[EuxTex]

Poinciana now, with her new livery, name and registration, will depart Juan Fernandez on Sunday for Fatu Hiva and meet her new owner. Alas, I am unable to accompany her across the Pacific. However, she is in good hands with her Uruguayan skipper and crew. I have full confidence in skipper Nieves and the crew she hired. God speed Senorita Capitan.

Is that your boat you've sold or are you delivering boats?
I ask because we are thinking of getting a new Legend e33 from the US over to the UK

[Aaronj09]

Nope, never, never want to, never going to.

The former. She is a Whitby 42 ketch rigged and has been sold to an Australian who has registered her in the French Marquesas. The deal was to deliver her to Fatu Hiva in those islands.

Are you going to do the crossing yourself? I have done the West to East crossing a few times, usually island hopping across the Caribbean then open ocean from Barbados to Cape Verde.

Wouldn'd do it myself. But the cost of shipping is £7k so was considering paying someone else to sail it over. All pie in the sky at the mo tho

Why not hire a skipper and crew her with you and other family members. Mind you, paying a skipper could be just as expensive, depending on the time the voyage would take, as paying freight.

It's a nice idea, would love to sail the Caribbean.

Poinciana is now underway enroute to Fatu Hiva in the capable hands of her skipper Nieves. Spoke with her awhile ago just as the boat cleared the harbor. Wish I could have been aboard for the crossing.

Must be sad to see her go. Are you getting another one?
