A Tozzo Frios conta com uma vasta gama de produtos como: frios, laticA­nios, embutidos, enlatados, congelados e produtos a granel. Location: Southern England Renato Levi Wrote three books on the subject of designing Powerboats.
Best book currently available on powerboat hydrodynamics is Hydrodynamics of High-Speed Marine Vehicles, by Odd M. If you are working in Aluminum, go to ABS, Lloyd's, or ISO and get rules for construction of high-speed vessels.
Jet boats are tricky, most major water-jet manufacturers have lots of data on what works, talk to the supplier. A phenomenon known as porpoising can occur if you are not caqrefull of what you are doing on the bottom, particurly in the 6' infront of the transom.
Make the delta pad on the bottom nice and long, no-one says that the boat needs a 'keel', where the bottom sheets meet to form the vee. Look at other jet boat manufacturers and what they do, we spend many hours making sure we get it right so we can sell a safe and well performing product. As has been said the key is power to weight and planing area in both laden and light conditions.
When making potentially dangerous or financial decisions, always employ and consult appropriate professionals. I never thought about that hell if you know it is a solid weld for all the seats and especially the bench seat hell that all acts like flotation.
Transom you're right is overkill, I've seen a transom similar to your but not that over built. I like the idea of diamond plate almost be nice to make the entire boat on the bottom out of it simply so you don't slip.
I have noticed that the boat runs better with a load up front and that is another reason for the hatch and storage up in the bow seat. I could run faster, but I can't run trot lines at 40 mph and some of the back water is tight.
Location: Galveston, Texas Building Aluminum Boats I have built two aluminum flatbottom boats. Location: Louisiana Thats pretty cool, I've never seen any boats like that in Louisiana but have seen a few down in Florida.
Also, by leaving the half pipe open at the back, I am able to use that for the live well drain.
Location: Galveston, Texas The 16' scooter I started April 2 011 and put it in the water the first week of June working on the week ends. Location: Louisiana I'd like to see more picture angles of the mud boat you built?
Location: Galveston, Texas The scotter does have storage under two hatches on front deck and even more in and under the CC. Attaching what I have, I will try to take pics after I put the mud motor back on this week end. Location: Louisiana Very nice I like the pictures of the one for the mud motor, I bet it really would fly with like a 30 outboard. Make your own quick and easy zip tie & ply mini boat - maximum fun for the least money! Intro, Braving the elements?I'm entering this build for the 'brave the elements' contest as this project has enabled me to get out there and experience the elements in my local environment.


I have recently finished building a cedar strip canoe, and had barrels full of thin, small pieces of cedar and ash left over. Spring was just starting to arrive in northern Minnesota, and after a long winter, I was getting anxious to get back out into my little wood shop and start another project.
Salt water, sunshine, and thousands of miles on a car roof rack can shorten the life of any boat.
I have a 13-foot kayak and a crowded garage, and horizontal storage (using a pulley system intended for a bike) was problematic. This Instructable will describe the construction of a heavy duty milk jug raft built out of recycled materials and capable of supporting over 700 lbs. Have you ever stood on the shore and looked out at people boating and wished you could be out there too? This Instructable documents how I built a small sailing boat out of a mussel float, and advice on how to build your own!
Today we're going to do a very quick, but functional, repair on a broken hand caned seat in a canoe.
I tried to build the lightest and cheapest (~150€ total material bill) sail-boat I could come up with. I've been wanting to combine my two favorite hobbies - woodworking and sailing for a long time, so I thought I'd build a boat.
I set out to make a simple rudder that did not cost the typical $250 but at the same time was a bit more effective than a plank on a stick.
Browsing Imgur one day I saw some guys that made a duct tape canoe, and decided to try my hand at the same.

The merc sj175 does offer a reasonable amount of thrust, but the downside is that in their infinate wisdom, Mercury put the exhaust from the engine in the cavity between the hull and jet unit.
I tend to think of those that do as 'old school', and perhaps we should scrap the shuttle and fly the appollo missions again.
As in aerospace, the trailing edges create a vortex, much like the tips of a wing, only in water that usually means that air is bled off, if that air makes it to the intake the pump will cavitate causing loss of thrust.
Thats really a good idea although the down fall like you have experienced is when you do weld that bench seat to the floor the bottom won't be perfectly flat and it creates a slight hook under the boat. I ask because I have always noticed when winter rolled around and it was cold out when i was welding those boats it just seemed like I had less distortion on the thinner stuff. They work much better than expected and the boat handles great in tight turns with no sliding. I just got a Miller 211 this past christmas and am hoping to start a small boat project as soon as i get my 220V wired into the shed so i can use the machine on some thicker stuff. One thing I wanted to do was build a kayak cart for when there is a distance from the car to the water.
Unfortunately by their nature they tend to be rather utilitarian and bulky looking and are not always very aesthetic to have sitting on your deck or dock.
I live in a town which is surrounded on three sides by water, in the middle of a river estuary. The pieces of wood were so small and thin I had been burning them in our patio fire pit just to keep them from taking up space in the garbage. A hand crafted ultra-light weight or wooden canoe needs specific preventive care at least twice a year.


These big buttons let you do it even faster because you don't have to wrap anything or poke them through holes. It's always fun, whether you're putting around the cottage dock, paddling through white caps in the ocean or going on river trips. We got an idea to make a sailboat out of items that we had around the house and bamboo that grew next to us. This project took me about four days working on and off and in a rush, so there were many corners cut and compromises made. Although this is not the correct way to repair these seats, it definitely works and will get you through until you can buy a new seat or properly hand cane the broken one. Item's neededHot glue gunWaterproof led strip from ebay12v 6800ah lithium battery The project cost's $40 total.
When a regatta starts the box sounds the horns at predetermined intervals: 5 minutes before the start, 4 minutes before the start, 1 minute before the start and at the instant of the start. It's a simple design where the boat sits inside of the loop and stays on by being pushed forward. The camp and canoeists were running into trouble keeping themselves dry while launching and retrieving the boats!
As I remember, they are nigh impossible to get hold of (you may have to order directly if you can find the website) but they are well worth reading. If you have a 'rocker' the boat will bounce around, or porpoise, if it has a hook it will bow steer badly, possibly causing the boat to spin in a turn.
Look at not only straight line performance, but also where any vorticied will end up in a tight turn (if you terminate your strakes ahead of the intake), if the unit cavitates during a turn and you loose thruse, a real nice jet spin often occurs, sometimes at an inconvient moment!!! My boat is a 15x52 and to tell ya the truth it would be dam hard going back to a narrower boat.
My next one will have the half pipes welded in the bottom to where the roll up the front will start. I want to start with something small and eventually build the 30 ft center console i drew up.
It was really beat up on the outside but the inside showed it had some good bones, ribs to be more specific. I have to look at the water every time I cross a bridge or pass a lake, and I envy the people I see on the water.
The other is a 12'X4' poling skiff, weight is 200 lbl 16 hp copper head mud motor not in this pic. I mean in turns just seems like with a higher center of gravity seems like it would want to roll.
Please email me some pictures of the next boat you start because what I see you do on this one has given me some idea on what I want to build. I have seen several cases where just a few minutes of more prep to keep small pieces straight when welding would have saved hours in the long run.
