Aluminium Hull Finish

[Pete Makra]

No not right at all you wont be getting the same strength at all most plate boats will use about a 5mm bottom versus pressed about 2mm to 3mm max. I have had pressed boats that will crack along where it has been pressed from constant banging over the years of the boat and they seem to always crack where it has been pressed. Imagine getting a piece of metal and folding it as soon as you fold it it weakens the metal and over time being a lighter gauge than the plate boat it will crack. It all depends on what your going to do with it, if your going out in the bay all the time and a bit of offshore work i would go plate but if your just going up the rivers and occasionly going out in the bay go pressed.

Thanks indy, I want to go outside occasionally but I'm pretty sure that the first time I take the missus out, will also be her last. She wont like it. We will mostly be bay/protected waters fishin I'd say. We found a great little place down the coast at Sussex Inlet NSW that we like and a mate took us out a few times in the inlet, but I tell you what, we pounded through the chop/swell a few times when the wind got up. I want the boat I buy to last me for some time so need to choose carefully, cheers Pete

<P><SPAN style="COLOR: black">Just a quick thing, the original question was regarding hull finishing i.e. stessco 3mm smooth&nbsp;sides verses&nbsp;quintrex pressed sides and other brands etc. Benny boy is right in the pressed market the 3mm smooth sides is just a look nothing more and to achieve that look it is better to use 3mm over 1.6 or 2mm, the weight difference will be minimal like 30kg max on top of the weight of the boat. A proper plate boat is&nbsp;built with 5083 plate and&nbsp;have a&nbsp;completely different under floor construction, the pressed side of the&nbsp;industry uses 5251 or 5052 which is a soft material for pressing without cracking. <o:p></o:p></SPAN></P>

Thanks boatie 72, so does that mean there is no difference between say a stessco with 3mm smooth sides and a quintrex with 3mm pressed sides , cheers Pete

Thanks Bennyboy, you explained it so it made sense. I do like the smooth look I must admit but weight is important I suppose. I'm looking at buying something around the 4.5 to 5 mtr range with a 60 to 75 on the back. Undecided about 2 or 4 stroke as don't really know the difference apart from one has better bottom end grunt and the other better economy. I'm hoping a 60-75 hp will be OK for the size I intend to buy, regardless of being a smooth or pressed hull, cheers.

Hi mate I am not sure where you are based but have a look at this link I brought myself one of these for xmas last year and so far I have 10 hours on the motor 60hp 2stroke Mercury for the price i tnink that they are a very nice rig. http://www.cunninghamsmarine.com.au/...overy_cc.shtml

G'day,

I've read through all the posts and thought there was some pretty good advice until you made this post.

If you are planning to go outside from Sussex Inlet you need a very sea-worthy boat. This area can produce surf at sea where currents meet and weather changes can turn the sea into a washing machine. Weather forecasts are well and good but this area seems to manifest sudden changes in the intensity of southerlys and is renowned for producing storms at sea that lash the south coast area of Sydney's suburbs.

There is no way that I would go outside from Sussex Inlet in anything less that 6M with 175HP to 200HP on the back. While it may just be the occasional trip outside it only takes one of these when it all turns to shit to kill you in a little boat.

I would broaden your search for late model fiberglass boats. The Sydney area has deep water ports and they don't encounter the conditions that make aluminium plate the boat of choice for many up here in Queensland.

Regards,

White Pointer

Thanks White Pointer, sorry haven't replied but been away. We go to Sussex quite often and haven't come across anything as bad as you're describing yet but I agree things can change very quickly, and not just in this area. By outside I mean a couple of kls offshore. You wont catch me much further out than this in any small tinny and I would never be out of sight of land. Safety first and I don't take risks, cheers Pete

Pete ,don't be confused 5021/52 is pressed/sheet alloy with is about 96 mpa (impact resistance) where as 5083 PLATE is 285 mpa (ir) weather it's 1.6,2,3,or whatever mm ribbed or not , which is like comparing sheet metal to hi-tensile and stressco IS NOT plate up to 5.3 mtrs unless they state it is 5083?. They state pressed in there ads ??? I would ask an reliable authorityon the quality of it before I'd purchased one just to be sure ..this I know ..PS still hate my boat ?
