Hi xander mate
Some great information above from ellicat and Ed. That will set you in the right direction.
I put heavier line on my reel than it says on the ratio. If the reel has only 7Kg of drag, you may want to only put 8 or 9 Kg line on it. Your reel won't break unless it is very over-worked, and somehow too much pressure is applied.

Zander Mate: These measurements are only just a guide for how much line of that size you should be able to put on the reel to fill it up.
Which is a bit misleading as 1) The manufactures are usually a bit optimistic in the capacity and 2) lines from different manufacturers can have different diameters for the same strength line.
As in a 30lb rated line from one manufacturer might be  0.60mm thick, another brand may be 0.50mm  and another brand may be 0.43mm, so there is a huge variation in the the amount of "30lb line" that a reel can take to fill it up, so obviously the thicker the line, the less line you can put on to fill up a spool. The other thing to be aware of is the actual line class that is stated. "Test" line is guaranteed and designed to break at slightly less than the stated capacity (for record  making purposes) ie; a 30lb test line might break at 28.9lb, and it is usually stated on the Line spool what it is,  whereas general run of the mill line may do the same or it could break at double what it is rated it.  Other things to be aware of is, that most, but not all reel manufacturers will use mono as the standard for line capacity,  but some will use line breaking strain and some will use line physical diameter  and lastly some will use braid as the standard as it is thinner and their reels will appear to hold more line than a comparable size reel, or a combination of all the different measurements to just add to the confusion. As the saying goes; the devil is in the details!
That is why you may see claims by line manufacturers of "ours is the strongest 30lb line"... That is because it's not 30lb line, it's possibly 40-50lb line but advertised as 30lb line! So at the end of the day it is a bit of a guessing game and just a marketing ball park figure to describe the reel capacity.
If you put on a stronger line than the capacity stated you should not " break" the reel. what will happen is that if you for argument sake, you put on 24kg  braided  line on a 2000 size reel which may only have a drag capacity of let say 5kg, the most that will happen if you wind in the drag to max, will be that the reel will hold the spool from spinning and letting out line till it reaches its max of 5kg, then the spool will slip as you have exceeded the reels 5Kg max drag max and it will start to let line out. Now that fish may stop before you run out of line or it may keep going.
If it keeps going then will happen is that if it is a big fish that can pull 24kg of drag on a long run  it will keep taking out line till you get spooled and then it is just the knot on the spool that is holding the line, as that particular reel is only a 2000 but you have 24kg pulling on it then yes it may break, the other situation where it may break is if you grab the spool with your hand to stop being spooled then you will still have 24kg pull on the reel and it may break as well.
Hope this explains it better.

got a new baitrunner D 12000, says mono line capacity 7kg.. does that mean if i get stronger line and reel something in larger then 7kgs is it going to break my real? would be much appreciated 

will be spending abit of time at urangan peir but sometimes i do like to venture off and have a flick somewhere else more secluded, if anyone knows anywhere that i can do this id be grateful to let you know and im still learning alot so you dont have to worry that ill take all the fish. i do prefer in the bush more then on a jetty so if anyone does know any creeks or anything like that where youd be able to walk up a fair bit and keep casting along the water thatd be great even if id have to travell abit i dont mind. also wouldnt mind a few hints on some lures or bait they may be helpfull around any of theres areas aswel and the kinds of fish that hang around, not looking after anything massive. cheers 

cheers guys could of been a waste of money there will definitely invest in something bigger 

Like the others have side, the problem is what happens if the weather turns. In theory you 'could' take it out from Gatakers, off Point Vernon, etc but any pickup in the wind and the swell will pick up and the waves will become choppy, which increases the danger. We stayed at Pialba Caravan Park as kids at Xmas time and dad and I used to paddle out in a canoe my dad made, with two of my brothers in the middle seats, to Pialba Reef. On the good days it was fine but I'll always remember the day the weather turned and we couldn't paddle against the waves back to the beach and instead had to be content with paddling towards a small gap in the rocks halfway towards Pt Vernon. I can't recall what mum was like afterwards but now being a parent myself, I can only imagine my dad copped an earful ......
Back to you, and I would seriously look at a 12ft tinny and whether you can make it happen, otherwise I'd settle for a 10ft tinny for the creeks and perhaps a sit on top kayak for cruising along the dropoffs near the rocks.

At a minimum 3.7m but for Harvey bay if you get a storm I would want a 4.2m with at least a 30hp. 

Hi xander mate
I'm no experienced boaty, but I know I'd want a bigger boat.
That size boat is best for flat waters, creeks, small rivers, etc. I wouldn't be taking it in any chop either.
Cheers Hamish

Yep too small mate. It would be ok to muck around in the creeks chasing mud crabs but don't take it out in the bay. 
 

Like others have said and IMO as well,  it is also way too small. Yes, you may be able to do that, but that doesn't mean you should,  If you have no room for it then see if you can store it somewhere, maybe at a mates place.
The sea is a fickle place it might be flat as a tack one day and getting out may be a breeze, but it can also turn on you very quickly and you may get caught, with boating it is not a matter of if, but when!

Go a touch bigger imo. 
10ft is only 3m. That's a tender for a yacht. 
 
12ft....or 3.7m is the minimum for a fishing boat imo. Once your loaded with gear, fuel, people etc.
Much more practical....and yes on good days you can head to fraser. Just watch conditions and plan your trips wisely. 
Windy days....stay in the creeks and protected areas. 
Calm days head out in the bay and down around the islands. 
 
To give you an idea....I've been 26k SE of waddy point in a 13ft tinny in 2m swell with not a breath of air around.
Had a 30hp on the back but never the less we had a great day and I caught my biggest whole green job fish at 13kg....I've lost bigger to sharks. 

am planning on getting a 10ft aliminium tinny, am based around hervey bay and would like to take it out to river heads, urangan, point vernon, burrum heads, torquay and so on, i am wondering how well it would handle the conditions in most of these areas, the weight on it would be only either me or me and a friend with some fishing gear, cant get a bigger boat due to storage yet so would really like to be able to make the most out of it till i upgrade but without risking anything going horribly wrong.. cheers :)
