Fishing Canoe Pics

[ricardo de oliveira]

Hope this post doesn't take much to load.
I just want to show here some pics of a working canoe from my area: Northeast Brazil, Ceará, Jericoacoara Beach ( check the Google Earth!).
Note the beefy scantlings, the tied fixtures and the absence of ballast and centerboards. Nothing like to keep things simple. They still go fishing under sail only around there. And the wind really pumps.

These pictures are great. Thanks, Ricardo! It's nice to see working boats without 10 coats of varnish. I love the low tech trapeze.

Thanks Ricardo for the fishing boat pictures. Those boats look very sturdy. What type of fishing do they do? Hook and line?

I thought you might be interested in my fishing boat. The hull is a Caledonia yawl but I've added a large live well which will also double as a dry well and a motor well for a 4HP Yamaha. It will also utilize an offset daggerboard for lateral resistance when sailing (center slot is for emergency supplies). The mast is something I've built to be out of the way of fishing for early in the morning when there's not much wind on the Gulf of Mexico where I sail (out of St. Marks Wildlife Preserve, Florida). Xena will not rely soley on sail for propulsion but at least she will only burn two or three gallons of gasoline instead of the 20 or 30 gallons burned by most of the other fishing boats in my area. You might notice that I also use a hardwood yoke with bamboo for my boom. I've wrapped the oak yoke with leather to protect my mast and sleeved the bamboo with composite fiber set in epoxy for strength.

Backfin, that cool trapeze is meant for "hiking for a living"! They do that all the time, since the boats have no ballast at all. Only some fish in the bilge, when they're lucky.
Kenjamin, they do hook and line and also set nets by night, recovering it in the first hours of the morning. What a nice fishing machine you got! Tell me more about wrapping bamboo in glass/epoxy. I'm doing bamboo spars for an outrigger canoe with crab claw sails. I had started with relatively thin bamboo poles and I'm thinking about increasing its stiffness gradually with glass/epoxy. Does epoxy resin glues ok to that slippery bamboo skin?

[MiddleAgesMan]

Maybe it would be more aptly named a hiking backstay. ;)

Ricardo, I let my bamboo age in my hot garage until it turns yellow. Then it gets a light sanding to get the surface some tooth so the epoxy will grip. I put the appropriately sized sleeve on the bamboo dry and wet it out in place. The tricky part is getting the sleeve past the exposed end grain of the cut ends of the bamboo. I've found that sanding helps but doesn't really solve the problem. Just cover the cut edges with some thin clear 3/4" office tape and the sleeves will slide on easily. Wet out the sleeve on the bamboo from the center. Wet and tighten the weeve of the sleeve with your gloved hand, again working from the center outwards. So far mine have been drying with some drips along the underside of the piece but I've got an idea to mount the drying pieces on a rotisserie from a barbeque grill. Maybe that will eliminate the drips.

Here's a web site for composite sleeves. There are others. I do not
profit from the sales of any of the composite sleeve companies.

I like the carbon/fiberglass red sleeves. They are attractive. I get my bamboo free which I guess helps pay for the expensive sleeves.

The yellow ones were in a trash pile next to the live stand where I get to harvest my bamboo. Good luck with your project.

[ricardo de oliveira]

kenjamin, I'm not going to find glass sleeves around here so I'm going to wrap some rounds of regular 6 oz. biaxial cloth. I want the cross strenght, too. Is fine sanding enough? The barbecue rotisserie idea is hot.
Mike, it looks rude and rude it is. In the old days they used to tie the loop around their necks. Evolution thought them that under the arm pity would be easier. I can say that come back home hiking in that thin poly rope is the leisure part of the day. OK, by night they go to the local bar and have some rounds of cachaça. But those guys are tough. Did you notice the finish in their canoes? They only buy sand papers, 40 grit, to wipe their noses in the hard winter days (80 F).:p

[kenjamin]

Ricardo, go with a medium grit sandpaper and try a spiral wrap with 2 in. fiberglass tape if you can find it. Raw cut edges of fiberglass cloth can be a real mess to work with. The two inch tape will have finished edges. Good luck.

Anything ever happen with Itaunas?

Great thread!

[wtarzia]

Ricardo, thanks for the pictures. I always thought Wooden Boat was most useful when it fostered the "ethnographic appeal" as opposed to the "fantasy boat" appeal ;-) I appreciated seeing the lashings, as they reminded me of all the ways Pacific people use lashings on their outrigger canoes. I have used some lashings on my own canoe, mostly to attach akas (cross beams) to the ama (float) and vaka (main canoe hull). lashings are great! Strong and stress-reducing. They also be used with a Spanish-windlass tensioner/quick-release (go to www.instructables.com (http://www.instructables.com) and search "Tim Anderson" and "canoe" and "Kenya" where he recently built a quick-built double outrigger (Ngalwa? sp?) on the Kenyan coast and used spanish windlass tensioners/releases). For permanent lashings, where I want tight connection but a graceful, slow "destruction" if it happens, I wrap nylon cord/rope then soak in epoxy. Epoxy does not stick to nylon, but when it saturates the nylon, it still results in a stiff assembly (can resemble 'sculpture' ;-) Best to wet the nylon so it stretches, let dry, then coat with epoxy, then paint the lashing to protect epoxy from UV.

Kenjamin, I love the way you store that curved spar. Interesting boat -- do you have a website for it? What's the center well-area? If seems best, private e-mail at wtarzia (at) nvcc (dot) commnet (dot) edu -- Wade

[kenjamin]

Hey Wade,
No Xena, warrior princess (battling convention), website yet but more pictures and discussion can be found here if you scroll down:
http://www.mavc2002.com/cyforum/viewtopic.php?t=607
The inner keel runs straight through uninterrupted so daggerboard slot is offset – underneath the bamboo boom in overhead picture. The center space above inner keel will store emergency supplies and will have a latched cover (eventually). Finished bamboo rear seat last weekend (so not in picture) The two big spaces midship are for 1) combination livewell, drywell, and motorwell and 2) space for three-day igloo ice chest and three gallon remote gas tank for 4HP Yamaha. Midship area to be covered with removeable bamboo mats so crew can sit there above all the stuff. Motor will mount midship and extend through bottom when waterproof hatch is removed.

Sorry Ricardo for the thread hijacking but Xena is all about fishing and she is sort of a very large canoe.

[ricardo de oliveira]

The delay in posting is due to a new trip to Jeri this weekend. I did a little more spying at the fishing canoe routine in that beach and I'm pretty amazed now at how they do go to windward - well, not that much - with such a keeless hull.
Kenjamin, that was not hijacking at all.
Philip, the Itaunas thing stoped after a conversation with an antropologist/journalist who knows a lot about that village. Maybe they're prone to selling Coca-Cola to the tourists for now. A lot of details from their culture and traditions must be restaured in an whole. It's not just about building boats for fishing but also about their singing, cooking, dancing, architecture etc. I felt like acting a bit naive about the process of a dominant culture swallowing the weakest. I don't know if I can express myself properly in English. But that's the story about it.

Ricardo, I understand what you are saying, thanks, it was and still is very interesting, trying to turn the clock backwards and forwards at the same time.

Those sails look a little like Jangada (NE Brazil sailing raft) sails. Is this a European or a native sail tradition? -- Wade

[ricardo de oliveira]

wtarzia,
that's a jangada sail or a crab claw sail.
http://meuslivros.weblog.com.pt/arquivo/jangada-3.jpg The The local canoes sails are more like an horizontal sprit rig set up. European? I guess. Native brazilians doesn"t sail at all. European influence is the only answer.

Last month I sailed in one of these crafts. What a thrill. Breaking the surf, dowsing the sails, hiking and lowering the centerboard gradually at the same time was really something. And then, surfing coming home...
