LOL!!!!
I'd think it'd be safer to secure a boat off the trailer. But securing it was not really my question. Tie the boat down.... well, duh!
Does it matter if the "scale" is at the front or the back of the boat? Is there a way to measure it with some kind of wind sensor behind the boat? (not a guy holding a tarp mmPat!) LOL
If pushing is the way to do it, and you put the load sensor against a big oak tree (for instance), what size of anchors would you have to have sunk into the ground? I suppose 4 anchors - a pair to secure the front, and a pair for the stern. But what kind of anchors would you use to not add drag, and throw off the measurement? I mean, in theory, you could tie the boat down so tightly that the thrust meter would read zero.
These are the thing we want to know so we can proudly post our numbers and answer YES!
LOL :lol:
I heard a comment from someone that they may be offering just this service - for a fee of course (which is no problem). But I'm not sure about that.

Or a cargo net over the bow would spread the force around too. But the force really isn't supposed to be there either.
I guess for the most accurate and safe measurement, you'd need to firmly secure the boat to some kind of sled with roller coaster style wheels on a track, so it can freely move front to back, but is restrained side to side and top/bottom, then measure the force of the sled by pushing or pulling.
Any tying of a boat on a trailer to the ground would throw off the measurements. But I suppose you could secure the boat to the trailer, then secure the trailer to the free rolling sled. But that's just more tie-down points that may fail.
Ah! :idea: Some kind of guides that the wheels can roll under & between that will allow the trailer to move, but not up/side to side. That's the ticket. Of coarse, that don't help the guys with fenders on their trailers.
The answer must be simple and easy, something anyone can do, otherwise, why would he have asked?

I can't say I disagree with you j.d. I'm the same way. Numbers would not mean much by themselves. BUT... I AM curious about it. Reason being, our boat is about at the bottom of the heap as far as power, thrust,... floating and so on. Improvements are going to be made.
Thrust is a real meaningful thing. it measures the motor & prop at the same time.
If there is some way a user can get accurate thrust measurements, every time I do an upgrade, I could test my thrust, and see how much it helped/hurt the persormance.... BESIDES what the seat of my pants tells me.
Because the seat of my pants measurement is motor, prop, and also the aerodynamic and hydrodynamic effects of the rigging and hull/trim tabs/etc.
Really, I could take it or leave it - Thrust numbers. Add more time/money is the way 99.999% of us do it. But if I do get them, they are worthless unless they are accurate, and consistant from measurement to measurement. But they would be helpful during some trial & error style upgrading.
One thing for sure, they never will be a bragging point for me!!! I can't afford to buy one of those performance motor/prop combos.... MUCH LESS pay for maintaining it and replacing it when it dies young from running so hard.
I know I'd buy the service from the SAO member who I think may have started on this as a business venture. At least once or twice. And coming from the same guy, the numbers would be consistant (which is critical to using the numbers)... and they'd be consistant from boat to boat - which means the bragging rights will be valid too.

Mood:
Just a thought. Not so much as thrust but if you want to check performance as far as engine goes you have a built in dyno. If you put the boat an the trailer and start it up stand on the throttle, note the rpm's. After you do some engine mods if the rpms go up you have an increase in horse power. Of course you have to have the same prop etc to compare apples to apples.
Not real technical but will give you and idea where you are going.

Just put the whole bowl in the sink and pour some fresh corn flakes.
At least we have a forum where we can read BS about airboats. I'd rather read BS about them than BS about who is getting an anullment in Hollywood.
Also, let me take this oppertunity to publicly apologize for and thoroughly deny any awareness of all BS posts I have made in the past.
