automatic gearbox for my boat?

Hello to all out there.My name is rikus veuger,original from holland but now living in bandung,indonesia.
I also want to build my own wooden boat and I am looking for many information by reading books and looking on the net.
But some questions I cant seem to get an answere for.So I try out here on this group.

It is maybe silly to ask but I am just curious to know why in a boat there is not a automatic gearbox.I ask this becouse I want to build a speedboat and I know that it take a lot of power to speed up the boat until it has
a surtain speed and start to get in plane.
Then you can lower the rpm of the engine but keep the speed.I thougt by using a gearbox the rpm can lower again,saving fuel and give more comfort.

My other question is about the angle of the shaft of the propellor.If the shaft and engine are on a angle it seems to me that, becouse of the direction of propellor power, the nose of the boat is lifted and the back is more down into the water.What is the use of that?
Is it not better to use a horizontal propellor,like a saildrive.It will give much more efficienty and it will be more pleasant to sit in when at lower speed becouse the boat stay horizontal.

I hope some one can give me some clear answere to one of my ,probebly silly,questions.

All the best

ps.I already put this message in this group 2 months
ago,but in the Articles so got only one replay.Hopefully
this time more people will react.

By the way.I am a trader in East Indian Rosewood,so if anybody needs some timber I can help you to get this great wood,almost any size or quantity.

Restortation project

Hi Everyone,

I am just starting on a new restortation project on a 1950  Blackwater Gaff Sloop. The boat is just been gutted and all the interior stripped and ready for a new traditional interior to be fitted once the few hull repairs are done. It will then be re-rigged back to its original Rig. Next Spring I hope to sail it across the North Sea to Holland and Belgium  to raise Money for my son's Epilepsy Charity and to raise awareness of Epilepsy in young childern.

Curlew Update

this afternoon I predrilled the screw holes for the bench seating.  I can pull these planks out now and prime the transom (I never got around to doing it when the rest of the interior was primed).  Then I can stain and varnish the benches and get plenty of varnish in the screw holes so they are resistant to moisture.  I need to get some 1-1/4" brass woodscrews for the benches - thought I had some but I guess not...

 

A friend has given me an old wood 'Snipe' sailboat.  It sounds like the hull is not salvagable except with a tremendous amount of work but the spars and sails are in good shape so I am planning on salvaging the hardware, cleats, chocks, turnbuckles, etc., and am thinking of adapting the mast to the Curlew depending on dimensions and soundness.  Otherwise I will continue with building my own mast and using the mast hardware from the Snipe...

How's Everyone Doing...

Kind of quiet around here right now...   Summer time, family functions, FISHING, house projects, FISHING, lawn mowing, baseball games, work of course, MORE FISHING...

I am very guilty of going fishing instead of working on the boat.  It is very tough living on a lake because the sirens call is pulling me out there instead of to the garage where I have a half-finished boat lol!!!

Anyway, is anyone actually working on their boats right now?

Flapjack launching

Well I just want to let you all know that the Flapjack was launched on June 20, at about 9:30 A.M. Pacific time (last day of Spring or first day of Summer, I’m not sure). The pictures that I posted do not show the detail I would like, but I want to share what I have. I still need to build the mast, sprit, and rudder, order the sail, and rig her, but she won’t sail until next spring. I promise that I will post better pictures (shot with a real digital camera) by then. I have to say that if she sails like she rows I picked a winning design. I am surprised that there has not been more written about this boat! Steve Redmond seems to have gotten it right and I would recommend this boat to anyone considering a 14’ rowing and sailing (although I can’t speak with authority on her sailing qualities yet) skiff. I rowed her about two and one half miles. She carries way well and is more stable that I thought she would be and tracks like she is on rails. With plans from Redmond and Thomas Hills book “Ultralight Boatbuilding”, she was a pleasure to build. This novice is thoroughly hooked. Until now I have only built one other boat, a kayak, but I will definitely build others. I would like to thank everyone who posts on this site for the inspiration (direct and indirect) I received throughout this project. I will continue to monitor this site and will look forward to offering what I can. I am proud to be a member of the boatbuilding community and can think of few activities that have been more fulfilling and enjoyable than “messing about in boats.”


Yours truly,

Winks
