What problems or benefits will I get with an aluminium boat hull

The anodes when attached directly to an unpainted area of an aluminum hull will protect any part of the hull that is not electrically isolated from the anode.

What defines a canoe or kayak is not hull shape, load carrying capacity, hull speed, comfort, or ability to handle big water. There are hulls available of both types that excel at speed, comfort or load carrying, for example. There are olympic white water slalom and flatwater (speed) racing events for both, and epic long distance voyages have been made by both, too.
Canoes are designed and built to be paddled with a single bladed paddle, and kayaks are made for double bladed paddles. This is what defines them. Verlen Kruger, perhaps the greatest modern distance paddler, said that he preferred a single blade for all day paddling because in alternating sides it gave some muscles a brief rest, and because the more vertical paddle shaft made for drier hands and boat.
Paddle craft may be the most varied water craft around. Browse around the web or explore your library or visit the Canoe Museum in Ontario, Canada, and you will see an amazing and wonderful variety.

Hello,
The manufacturer of the boat should be capable to give you the make/type/power/serial information if you give them model and serial of the hull.
At least if it wasn't changed during the lifetime of the boat.

Hey Joe,
Wow.. where to start.. there are so many things that will cause the issue you are describing.What type of electronics do you have? Does this happen at all speeds? Where is the transducer mounted? I need more info about when it stops reading.
1.Wrong setting on the unit
2 Bad transducer
3 Bad transducer mounting (either inside the hull or outside the hull.)
4. (In hull) Turbulence going under the boat (mine quits reading at about 55 mph @ half trim...the boat is lifting so much it causes air pockets so the transducer loses contact with the water)
5. (Outside hull) Turbulence around the bottom of the boat where the transducer meets the water.
Good luck,, when you get the info.. reply to me..

There is a product on the market called aluweld it melts at a lower temp to normal aluminium but makes a permanent repair as long as your hull is pure aluminium shouldn't have a problem look online and contact the sellers for more info

Happy boating, Pete

Oilcanning is a fairly common problem usually caused by improper storage or transport of your kayak, especially if it's hot out. Gently heating your hull (either by laying your kayak upside down in the sun on a warm/hot day or by using a heat gun CAREFULLY) MIGHT pop the dent out. If you were dealing with a single-hulled kayak, a little gentle pressure on the area with the dent while it's warm/hot would definitely do the trick. Not sure how I would approach a double hulled kayak, but it would probably be a combination of heat and pressurizing the inside of the hull or heat and water on the inside of the hull...would have to experiment.

Might help to tell us what kind of boat - deep V hull 22 ft.? bass boat with shallow V hull? Some need the transducer closer to the centerline of the vessel while others do better more outboard, Naturally they need to be flush with the hull no matter where they are located. Depending on the transducer, you could also try properly mounting it inside the vessel near the transom. Good new is you are getting good info from it. Cheers Pete

I don't have much experience of radio transceivers but I do have a couple of ideas.

The big question is how do you know your radio transmits 30 miles but receives only 6 miles?
Clearly you have a friend with a transceiver and you have been playing around together until you formed those conclusions.

What if the other radio received well but didn't transmit so well? Have both radios been checked with a field strength meter to ensure they are both radiating similar power outputs?

Do you receive the carrier wave but no audio at a range greater than 6 miles? If so your friend's radio (and others) might have a modulation problem. Has the signal(s) been analysed with an oscilloscope?

It is often imagined the transmission envelope is circular radiating from the antenna at the centre but that is often wrong. The radiation envelope is often distorted by a ground plane. Imagine an antenna mounted at the centre of an aluminium boat hull, the radiation envelope would be elliptical in line with the hull.

Even with a fibreglass hull the presence of metal masses can pull the radiation envelope out of shape lengthening the range of both transmission and receiving in one direction and shortening them in another.

There is another possibility to poor reception and that is a high amount of interference that might be airborne being received by the internal radio circuitry, by several means - antenna or the poor screening of the downlead and could be aggravated by poor grounding. Interference can also be on the supply line and both types can be generated by a host of electrical or electronic equipment.
Generators and motors, voltage regulators or stabilisers, local oscillators, fluorescent lighting, inverters, computers...

The basic radio of the old days could have the Squelch turned off and an experienced operator can hear much of what is or isn't happening.
