Long Steps.
I think that I’ve mentioned before, that in my plans range
we have “Tread Lightly” which came from a little poem about how we should treat
the earth on which we walk (metaphor), and “Walkabout” which is an English
language word for the spiritual wanderings of the Australian Aboriginal people,
and that “Long Steps” is the next in the series of names. I am wanting to travel further, to see new coasts, to explore new territory both
within myself and in terms of where I will sail.
Hence “Long Steps”.
To sail along the
coast of New Zealand is a real adventure, there are wonderful harbours, tiny
sheltered coves, rivermouths and amazing beaches to explore. There are though stretches where there are
cliffs and reefs, where a haven from foul weather may be long way off, and any boat venturing along
there needs to have both a cautious skipper and the ability to cope with
seriously bad weather.
Other considerations are that the boat should be fast. Not blazingly fast as in a racing boat but the
difference between a conventional sailing dayboat which will average 3.5 knots
over a days sailing and one that will average 5 knots is going to make close to
two hours difference when covering a 35 mile days distance. A boat that will maintain a good speed on all
points of sail and in a wide range of
conditions without stressing the crew is very desisrable when covering
long distances day after day.
By not stressing the crew, I mean that it should offer some
protection from wind and spray, several comfortable seating positions, a place
where the boat can be helmed standing
up, and she should have a comfortable motion in a seaway.
Further on the stress and fatigue issue, the force needed to
adjust the sails sheets should be low, the helm should be light, the boat
should track easily and be able to hold a course without the skipper at the
helm.
Very very important, as she is intended to go into remote
areas far from possible assistance this boat has to be such that she can be self rescued by her solo skipper
in case of a capsize or swamping.
She has to carry a weeks worth of stores, gear for cooking
and camping aboard including a really effective tent, ground tackle so she can
anchor , communications and safety equipment, spare clothing and a bucket.
There are lots more considerations to mull over when I’m
chewing the end of my pencil sitting at the drawing board, too many to list
here.
Designing or all of the above is a big ask, and the design
work started well before picking up the pencil and drawing “Long Steps”. I’d written all this out, quantified it, estimated
weights and spaces, identified out the target
hydrodynamic numbers and the shape required to fit all of that before I
started working on the shape of the hull and the rig.
So here is the solution to the equation, Long Steps is 5.850
long plus boomkin and in my case a short “prod” bowsprit for a single luffed
spinnaker. She’s narrow enough to row,
has a self draining cockpit floor that’s 0.600 wide by 2.7 long, has around 140
kg of water ballast, a “standing up”
area just ahead of the tiller, and I’m planning to put a swimming pool beanbag
in there as well to ease the back and butt. Sshe has over 2 tons of bouyancy
built in, all of which can be accessed through hatches for stores and equipment,
and of course there is the little
“cabin” which is really a raised storage and bouyancy chamber with
a cuddy, now called the “Cuddly” in the
case of my SCAMP design which the idea came from and which is a practical and much
loved feature of that boat.
The hull shape is a development of the Walkabout, fast, dry,
easily rowed, with the ballast, the offset centerboard and self draining
cockpit of the SCAMP.
The rig is the lugsail with mizzen yawl that’s become
popular on several of my other cruisers, and, well, its time I stopped rambling
and showed you the pictures.
We have below the
body plan showing the shape and structure. The second is the rig, note
that all the fittings are listed, they’re all from the Duckworksmagazine
catalogue, good gear at a good price by the way. DW will have the fittings list and can supply
a package deal including all your bits of string.
The third page shows, in response to a short thread on my
Facebook page, how the lap joints in the planking are made.
Apologies in advance for the poor pics, I went and had them scanned but the Blogspot system wont accept them so its back to an inadequate camera.
Watch this space, I’ve only a couple of sheets of plans to
draw now, and will be starting the build very soon.

ReplyDeleteI loved the way you discuss the topic great work thanks for the share Your informative post.

John, I know it's early, but any chance of plans for a slightly longer enclosed cabin for those needing more protection from the elements overnight and to keep everything completely dry??
ReplyDeleteI think the hard part with that might be rowing. You might gain another 30 or 40cm, but then you might also be afraid of smacking the back of your head on the cabin top on full extension.
DeleteI personally would think about a soft bimini style tent you could hook to the edge of the cabin with snaps of something similar.
