Tinnies on the roof are huge fuel guzzlers. The stop air flow.

Many exceed the legal and safe load limits. And don't forget all the other "stuff" that you need to find a place for too - motors, oars, fuel, ..... it is a long heavy list. Think very carefully before you do this. Many get carted around the country at great risk and expense only to find that it is simply too much trouble to get them down and fit them out to use them for less than a couple of days.
Do you think this is legal and safe? Check all the stuff on the ends of the van!
If you want to take a boat, get a suitable motorhome and tow it.
Just to clarify my point. The RACQ, I think, did some tests a few years back. They found that a tinnie on the roof was just a huge airbrake. Wind got up inside of the tinnie and slowed the car and sped up the fuel consumption. They compared the same car with the same tinnie on a trailer and found the trailer was way safer and more economical to tow.
But if you are towing a caravan then the options are limited.

Hi Caravan Happy,
We have. The old tinnie was washed down and dried before lifting onto the roof. I polish the car before, during and after each away trip. the truck is 2012 old and have had zero problems. our trips last 12-13 weeks away.
We upgraded the tinnie to a custom made SeaJay nomad 3.85mtr HS (highside). Picked it up January 2020 and along came Covid-19.
Had a GVM up grade in September on the GX 200. Then Set about making my own rear loading boat loader. IMO the commercial stuff is not up to my standards. my roof has eight mounting points with 16 bolts direct into the roof proper. With a 200kg total carrying capacity, including the rack @ 43kg. Where as the GLX, VX, and Sahra all share six points.
The new tinnie sits so low on my rack its built to the mm. I had commercial sized lifting eyes welded inside to eight ribs, as part of the build of the tinnie. No straps or ropes to hold it down. I use turn buckles inside the hull.Zero strap or rope drag. Zero wind noise. Don't ask what it cost me to have the tinnie custom built and the rack costs.

Hi Jo-anne.Whilst I can offer no useful advice with regard to how paintwork is affected,it is vitally important to consider the extra weight applied to your car's rear axle by having a tinnie on the roof,if you also are towing a caravan.Your car will determine what your actual weights are,but do not fall for the GVM upgrade fallacy.Many people do a GVM upgrade,costing thousands of dollars,on a popular model,which adds only 50kg.....yes,50kg....to that car's rear axle capacity.This is a great advantage if the vehicle is to be used solely as a tourer,and is loaded correctly,but if a trailer is to be towed,the gain in capacity is negligible.Peter's first picture is a perfect example of an overloaded,unsafe and thus uninsured vehicle.Cheers.

As others have said. Be very careful you have your weights within legal limits.
There was an article written a couple of years ago with an interview with the head of Victoria's police division dealing with overweight vehicles.
One of his comments was very pertinent in as much as he said that as soon as they saw a car and van with a dingy on the roof, they pulled them in to be weighed as 90% of them were overweight.
Obviously the dingy makes you an immediate target.

--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------Hi Yobar and happy New You and everyone here,
I could not agree with you more on that Photo of Peters. It's one of many of the commercial boat loaders available. The hight of that tinnie, between the cars roof top and the gunnels of the boat, What a shocker. The people who design and make these carriers, they call themselves experts in this area. What a joke. Add the angle of attack for the air flow, plus it has 4 screw clamps to hold it to the boat /loader carrier.
I would go as far to say, that 200 is stock standard. Even before we did our gvm upgrade, our GX200 never sat down in the rear, like in the above Photo.
We had standard air bags in ours. And we carry a lot of gear.
The cost involved is, costly to get it right. Retirement allows me the time to be in the workshop getting it right. I have worked flat out throughout my life. It's ok now to spend a dollar here and there, to go fishing.
Do what you love, and do it often. Life is short after all.

Hi Grey,
I would suggest that the back of the LC200 is down because of the Kedron van attached, probably a good 3500 kg.
As a matter of interest I googled the weight of a rooftop tinnie and was surprised to know they are only 60 - 80 kg, I think with your homemade rack sitting low to the roof, it would be fine.
I have even heard of better fuel economy when towing a van as it deflects the wind over the roof of the van, extra weight issue aside.

Bob,you seem to forget that,although the tinnie is "only 60-80kg",John's owner-built boat loader weighs 43kg,so he has an EXTRA 123kg on the lightweight rear axle of the car.This rear axle is the problem....even after John spent big dollars on a GVM upgrade,he still has a rear axle rated at only 2000kg....yes,only 2000kg, and airbags will do absolutely NOTHING to manage that weight.Using airbags to make the vehicle sit level means absolutely nothing,yet John tells us "we carry a lot of gear".As I have stated many times before,if John is towing a decent sized van,his car will be overloaded on the rear axle, unsafe and uninsured.Cheers

I actually didn't need clarification on that Yobarr, I was good at maths.
You seemed to have lumped it all on that magic rear axle again, rather than take into account Grey's statement that it is rated to 200 kgs and spread out over 8 fixed points, probably about 80 kg at the back.
I am sure John has taken everything into account and had his rig weighed with the tug after his upgrade.
My point was that tinnies are lighter than I thought.

It doesn't look like the centre point of the roof is halfway between the axles.
Tinnies are a bit heavier at the rear so their so their centre point will be a bit towards the rear.
Just need to sketch up the dimensions to work out where the load is.

Perhaps the weights argument, sorry discussion, could transfer to the Weights sub forum, and this can just be about the effects of unwashed boats dripping onto vehicle duco, which was the question asked.

Good comments Jonathan,with a degree of logic apparent,but it matters not where the load is.John already has said that "we carry a lot of gear",and it is highly unlikely that he is within his his 2000kg rear axle capacity,GVM upgrade or not,even before the tinnie is put onto the roof.And I will say again,airbags do NOTHING to help axle weights.Cheers.

Hi caravan happy
I have had my tinny on the roof for just over three years now and have a white aluminium canopy and have never had aluminium runoff as its washed regularly but you might on top of the canopy under boat .You probably get salt sand and crap out of boat more than aluminium.
Try to ignore the dooms dayers if you set it up right when your in the water its all worth it

Hi Bob & Jayne,
2 x. You must have had a sneak preview of our rig. We are fully legal. Our new tinnie weighs in with turn buckles @ 121kg She is a 3.85mtrs with a beam of 1.86mtrs.
Has a fully welded 50mm x 25mm x 3mm tube frame that runs 8mm x 20mm channel lock nuts pulled into place and bolted through a full length s/s rib. the 3000lb 12v winch sits tucked up underneath the front of the tubed frame and is powered from a 50amp Anderson plug from the rear.All this fits under the rib backbone. Took a lot of maths to work out too. Purpose built for this boat. It sits on four cross bars so the weight is supported across the entire roof.
Our Jack russell rides up front on the centre console. So there goes another 10kg, forward away from that rear axle. Sorry Chris, We are Legal in all respects.
The boat sits well forward and carries more weight onto the front axle.My motor is bolted to the floor behind the front seats.
Live your dreams and share your Passion.
Regards Grey (Jim)

This group of protagonists never let a thread topic get in the way of a weight argument. I don't necessarily disagree about a car topper making vehicles overweight, but that wasn't the question asked or information requested.
The OP asked a specific question about the car topper.
People need to answer what is asked, not tell people what they want to spread. If they don't have the answer requested, then just honour the poster and don't drag the topic to what they want to go on about. Simple as that. Too many topics are now being dragged back to weights which quite frankly is getting very bloody boring and repetitive. There is a weight forum. Use that and let others just enjoy the Non Weight Forum.
And please don't tell people just to scroll past and not read, which is often the response. Why should we have to? Others should just leave topics about what is in the OP's post.
Anyway, that's me done on this.

If I put a piece of aluminium on the roof racks will affect the paint. The answer would be no.
Or

Sorry I do have to answer this,
If you are referring understudy understudy to yobarr?, no I'm not but thanks for the compliment.
I dont think you understand how lucky you are to have someone like yobarr on this forum at worst he bores and aggravates some people ,probably the ones with overweight dangerous vehicles.
At best he might save someones life and that of their wife or passengers.
I for one admire his tenacity and hope he stays here ,though god knows why he does so .
I believe GCM upgrades should be banned and probably will when the authoritys get their act together.
How can you add 300-500 kg to a gvm and not affect the braking by quite a margin ,without upgrading the brakes .
more weight over the dreaded rear axle makes the car less stable, takes weight off the front axle , the front brakes normally do most of the work anyway are now even less efficient.
Also steering will be less responsive . not to mention bent axle ,would be disastrous accident potential.
The picture of that Kedron Rig up above says it all, I for one hope I never happen to be travelling on the same road as that guy in the opposite direction.
As for putting 200 kg on your roof ,if there is one really bad place to add weight to your car thats it .
Keep it up Yobarr yer doing a grand job mate .

Many exceed the legal and safe load limits.
And don't forget all the other "stuff" that you need to find a place for too - motors, oars, fuel, ..... it is a long heavy list.
Think very carefully before you do this. Many get carted around the country at great risk and expense only to find that it is simply too much trouble to get them down and fit them out to use them for less than a couple of days.
Do you think this is legal and safe? Check all the stuff on the ends of the van!
If you want to take a boat, get a suitable motorhome and tow it.
Cheers,
Peter
But if you are towing a caravan then the options are limited.

Hi Jo-anne.Whilst I can offer no useful advice with regard to how paintwork is affected,it is vitally important to consider the extra weight applied to your car's rear axle by having a tinnie on the roof,if you also are towing a caravan.Your car will determine what your actual weights are,but do not fall for the GVM upgrade fallacy.Many people do a GVM upgrade,costing thousands of dollars,on a popular model,which adds only 50kg.....yes,50kg....to that car's rear axle capacity.This is a great advantage if the vehicle is to be used solely as a tourer,and is loaded correctly,but if a trailer is to be towed,the gain in capacity is negligible.Peter's first picture is a perfect example of an overloaded,unsafe and thus uninsured vehicle.Cheers.
Hi Grey,
I would suggest that the back of the LC200 is down because of the Kedron van attached, probably a good 3500 kg.

Tinnies are a bit heavier at the rear so their so their centre point will be a bit towards the rear.
Just need to sketch up the dimensions to work out where the load is.
Perhaps the weights argument, sorry discussion, could transfer to the Weights sub forum, and this can just be about the effects of unwashed boats dripping onto vehicle duco, which was the question asked.
That is especially pertinent as the OP never specified their vehicle, and this thread is now being argued, oops sorry, discussed, around some unknown persons vehicle!

Good comments Jonathan,with a degree of logic apparent,but it matters not where the load is.John already has said that "we carry a lot of gear",and it is highly unlikely that he is within his his 2000kg rear axle capacity,GVM upgrade or not,even before the tinnie is put onto the roof.And I will say again,airbags do NOTHING to help axle weights.Cheers.
Hi Ian....It matters not what vehicle the OP drives,as almost any car that is towing a caravan is likely to be overweight on its rear axle when another 120kg is simply whacked onto the roof.And where is the outboard motor carried,and what about the fuel? Life jackets.Oars.Safety equipment?Cheers

Hi caravan happy
I have had my tinny on the roof for just over three years now and have a white aluminium canopy and have never had aluminium runoff as its washed regularly but you might on top of the canopy under boat .You probably get salt sand and crap out of boat more than aluminium.
Try to ignore the dooms dayers if you set it up right when your in the water its all worth it
Cheers
Yobarr, you just sing the same song all the time.................rear axles
120 kg on the rear axle from a tinny on the roof, weighing 120 kg all up, you forgot the rod and reels, maybe some bait or maybe the dog in the back seat.
As I said before, maybe the rig is legal in all ways, give it a rest.
Cheers Bob
If you have an onboard hose to wash everything down then there is no issue with paint!
Hi Bob & Jayne,
2 x. You must have had a sneak preview of our rig. We are fully legal. Our new tinnie weighs in with turn buckles @ 121kg She is a 3.85mtrs with a beam of 1.86mtrs.
Has a fully welded 50mm x 25mm x 3mm tube frame that runs 8mm x 20mm channel lock nuts pulled into place and bolted through a full length s/s rib. the 3000lb 12v winch sits tucked up underneath the front of the tubed frame and is powered from a 50amp Anderson plug from the rear.All this fits under the rib backbone. Took a lot of maths to work out too. Purpose built for this boat. It sits on four cross bars so the weight is supported across the entire roof.
Our Jack russell rides up front on the centre console. So there goes another 10kg, forward away from that rear axle. Sorry Chris, We are Legal in all respects.
The boat sits well forward and carries more weight onto the front axle.My motor is bolted to the floor behind the front seats.
Live your dreams and share your Passion.
Regards Grey (Jim)

Live your dreams and share your Passion. Dreaming key word .
Me thinks maybe another case of ."YOU CANT FACE THE TRUTH !!"

Sounds like you are the understudy to another forum member with a RANT like that.
Cheers
This group of protagonists never let a thread topic get in the way of a weight argument. I don't necessarily disagree about a car topper making vehicles overweight, but that wasn't the question asked or information requested.
The OP asked a specific question about the car topper.
People need to answer what is asked, not tell people what they want to spread. If they don't have the answer requested, then just honour the poster and don't drag the topic to what they want to go on about. Simple as that. Too many topics are now being dragged back to weights which quite frankly is getting very bloody boring and repetitive. There is a weight forum. Use that and let others just enjoy the Non Weight Forum.
And please don't tell people just to scroll past and not read, which is often the response. Why should we have to? Others should just leave topics about what is in the OP's post.
Anyway, that's me done on this.

And that is the way it will stay.

If the question was.
If I put a piece of aluminium on the roof racks will affect the paint. The answer would be no.
Or
If I put a piece of aluminium on the roof which has been in salt water will it affect the paint. The answer would be wash it first.
The question should have been more specific!
x2....Thankyou Peter.My sentiments exactly,but I as afraid that I may not be as diplomatic as you have been.Cheers

Sorry I do have to answer this,
If you are referring understudy understudy to yobarr?, no I'm not but thanks for the compliment.
I dont think you understand how lucky you are to have someone like yobarr on this forum at worst he bores and aggravates some people ,probably the ones with overweight dangerous vehicles.
At best he might save someones life and that of their wife or passengers.
I for one admire his tenacity and hope he stays here ,though god knows why he does so .
I believe GCM upgrades should be banned and probably will when the authoritys get their act together.
How can you add 300-500 kg to a gvm and not affect the braking by quite a margin ,without upgrading the brakes .
more weight over the dreaded rear axle makes the car less stable, takes weight off the front axle , the front brakes normally do most of the work anyway are now even less efficient.
Also steering will be less responsive . not to mention bent axle ,would be disastrous accident potential.
The picture of that Kedron Rig up above says it all, I for one hope I never happen to be travelling on the same road as that guy in the opposite direction.
As for putting 200 kg on your roof ,if there is one really bad place to add weight to your car thats it .
Keep it up Yobarr yer doing a grand job mate .
Regards your understudy Orid
