|
|
my neibour just bought a 21 ft steel hulled jet boat it has a berkely pump and a 350 in it for power we went for a rip and this boat gos 56 mph gps reading and gets up on step fairly fast for a heavy boat what we are trying to find out is who made steel hulled boats in alberta and are they or were they common it looks like it is not to old and the previse owner had no idea where it came from thanks any info would be cool

Clement boats were steel bottom with aluminum sides. It may be one of those? Any pics? |

If I see you stuck on a rock bar, forgive me if I turn the other way and put my foot down! Gotta be twice as heavy as Aluminum? |

In the early seventies a guy named Ross Smith built an all steel boat in Reddeer The boat performed very well and as all boats of the day its trailor had mobile home axles. This hull I believe had a aluminum windshield frame. |

I lifted this boat off the trailer with my t-300 bobcat with no problems at all it is rated for 3000lbs but can lift abought 4000 before it tips so between 3000 to id say 3800 lbs with no fuel |

When i built my steel hull it was (295 Kgs).. 6mm Delta 3mm outers and 1.5mm sides and top, Plus it was only 4.1 mtr's long...
But i had a hull built ( Alloy) same length and had a 10mm Delta 5mm outers and 3mm sides and top and came in at 260 kg's ... All this is hull only
So in my case the differance between Steel and Alloy is not a lot when you look at the Big Picture...Cheers JR _________________ Life is Short, Play the cards you get, Go Hard or Go Home..... |

Steel is an amazing material. I always thought that if it was discovered now it would be considered a wonder metal. It is significantly stiffer than aluminum and much stronger. Also, it gets stronger with welding not weaker so repairs and seams are not a weak point. It also deals with stress and vibration much much better. Below a certain threshold steel with take abuse infinitely while with aluminum stress is generally cumulative eventually resulting in failure. The major drawbacks to steel is its weight and oxidation. It is heavier per volume but not per unit of strength. Aluminum's lighter weight allows it to be used in lower strength applications while retaining material thickness that adds to its rigidity. Since steel is stiffer for its strength it ends up too thin in low strength applications to maintain rigidity with out creating a tin can effect. So in lower strength applications where rigidity is needed aluminum is able to be used. I am sure that there is an engineer on here who can explain it better but it seems to me that a steel hulled boat could be made to work in our application very well with a comparative weight and strength. You just have to get past the rust.

thanks for the very detailed explanation the boat does actually work very well for us. |
