The c/b does that, too, as it pivots back nicely. I have a pennant
going fwd to a block then back to a clam cleat under the centre thwart so I can raise it a little at a time to keep max plane. When you hear the grating noise, it's time to haul a bit more.

Leeboards will _still_ give you some lateral plane (also tunnel effects) at the point where you have your c/b all the way up and there's only 1cm of water under your keel. That's true. The leeboards are better at the super-shallow sailing. But they also have twice as much drag. Not sure if the "tunnel effect" is helpful or hurtful, that kind of hydrodynamics is very picky.

Remember to take it easy at first, that's the difficult part. I tend to get all wound up and pull like hell then suffer later. Short strokes, Peter, Short strokes. My nymph dinghy only allows 7ft oars, and it's a real bummer at first to respond to the little strokes they enforce (hard long strokes tip the dinghy over... ??? Never had that problem. Another useful technique is to alternate sides, this keeps the stroke short. It makes the boat waggle from side to side but if you get the timing right this helps visibility. How is the CCA pine doing as its own antifoul? Nothing seems to be living on it. Now I'm curious. What is "CCA pine?" Gonna haul this afternoon. I've decided the bowsprit was a good idea but now there's too much lee helm. I'll make a new mast base about a foot back and then make a new set of stays & shrouds to suit. I never did like the existing chainplates anyway, and I have a huge supply of scrap. Keep in mind this is going to change the sheeting geometry. A foot is a lot! You sure you don't want to trial it at a bit less? How far back have you raked the mast? This will give you a good way to measure how far back to move the CE. .... Sometimes I think I took up boats to finally have a hobby where I'd never run out of things to do, things to change, things to repair and tools to play with while doing it. The sailing side is pretty cool, too. Moderation in all things... don't be like Vito and focus solely on working on the boat! You _could_ have rigged unstayed, it would be saner if less weatherly for such a craft. Not necessarily less weatherly. The engineering would be a bit more intense, remember he's flying a bigger headsail. Might build an elongated Buehler Pogo next, just for fun. Gaff schooner rig. I have a Yanmar 3HP diesel engine with g/box that needs a boat. Ah. I retract my previous statement. Nothing wrong with your sanity index.

Copper Chrome Arsenate pressure-treated softwood. "PermaPine". Impervious to rot, lethal to borers, white ants, unfortunate propensity to poison you if used as barbeque fuel, but also prone to explode when overheated...when it disintegrates, leaves traces of (you guessed it) copper, chrome and arsenic.

Yeah, but he doesn't need to be a hyperfit young adult to drive it, either. FT2 is going to come home from Port Augusta soon, get stripped back to wood-epoxy, critical things fixed, then sold as is. Harsh physical reality is I'm unlikely to sail her again and I need all maintenenace time at present to keep Lady Kate happy.-- Flying Tadpole ------------------------- http://www.ace.net.au/schooner http://music.download.com/timfatchen http://music.download.com/internetopera |

That's true. The leeboards are better at the super-shallow sailing.

I thought you mean the pressure change due to flow between the hull & leeboard. BTW a centerboard can be set to angle itslef slightly to windward, just like toe-in with leeboards, bilgeboards, or catamaran foils. This used to be called a "gybing" board and it's a big help. ???

snip Not sure if the "tunnel effect" is helpful or hurtful, that kind of hydrodynamics is very picky.

I thought you mean the pressure change due to flow between the hull & leeboard. No, the distance I had the leeboards out from the hull was one thing and their toe-in another (FT1 had leeboards mounted on an outrigger boom, not directly on the canoe's hull. And the hull was still widening at the point the boom crossed it, so water flow faced a constrciting passage, not parallel. A few cm in or out made a surprisign difference. Then I fiddled with the toe in .) BTW a centerboard can be set to angle itslef slightly to windward, just like toe-in with leeboards, bilgeboards, or catamaran foils.

Remember to take it easy at first, that's the difficult part. I tend to get all wound up and pull like hell then suffer later. This boat had rowlocks on it but the wood was all rotten, so when I stripped it back, they went. Only take me a few hours to replace them. It's on the job list. Gonna haul this afternoon. I've decided the bowsprit was a good idea but now there's too much lee helm. I'll make a new mast base about a foot back and then make a new set of stays & shrouds to suit.

You sure you don't want to trial it at a bit less? How far back have you raked the mast? This will give you a good way to measure how far back to move the CE. It's a PITA. The existing stays were cut to exact length by the PO so you can't adjust rake without cutting them, adding turnbuckles etc etc. By the time you do all that, might as well make a new spot to put the mast too. Moving the mast aft to the fwd thwart is the next good strong point to feed thrust to the keel; I rebuilt all the woodwork so I know it'll handle any load likely to be inflicted on it. I might be able to do less than a foot, haven't really measured it yet. The boat is now next to the shop ready for work, I hauled it last night on the high tide. Having a waterfront makes things simple. I built my own beach launching ramp. Ah. I retract my previous statement. Nothing wrong with your sanity index. I guess all is relative ![]() http://www.georgebuehler.com/pogo.html Looks like a fun boat, but it's a lot heavier than FT2. Yeah, George says it's a minature displacement sailboat not a dinghy. Pretty simple to build IMO. I've had the plans for 2-3 years, promised to build one for my youngest daughter. It won't go fast but it probably won't drown her either, and you could go fishing from it easily. Nobody is going to worry overmuch if you run aground, bounce off the odd oyster covered rock etc etc. Pretty cheap to build too, so if/when you don't want to play with it any more, you can pass it on to someone else to play with cheaply or even for free.
