Lap Sheets
 

Going forward from the Solomons race, lap time sheets will be posted on the OPA website.


Where to find them? You will need to navigate from the "Results" tab to the specific race you are looking for. Then click on "Lap sheets" (see below picture), document will open in a new window

or go to the "Site Map" which is available on the bottem of every page of the OPA Website

If there is a lap sheet document for that particular race, you will see them listed below the Race, click on the link "Lap Sheet" and it will open in a new window

Great Job Dee, Thank You

I can't take the credit for doing them, it's all Sam. I just get it up there on the website :)

Very cool - but a quick question on class 6 as our B/O speed is 70mph and Wazzup II ran 70.50 (approx) for a "LAP" Average? .. how the heck do you read this?

Its a little funky, Whoz Your Daddy didnt break out, but had one lap where they averaged 76.3

I do like seeing the lap times though, very cool Dee!

Yes something doesn't make sense. We watched the GPS like every one else and saw 75.0 2 times max how did we end up with a76 mph average?

Maybe it was done by time/distance for speed calculations..depending on what line you took the distance would change

The average speeds according to our lap sheets are not correct. My guess is the distance entered into the computer program was estimated and it calculated avg. speed based on wrong info.

So what you guys are saying is that when you make turns, you dont shed any speed??? Avg lap speed is exactly what it says. The old rule of thumb was that your avg was approx 6-8 mph under your top speed when you factor in turns.

Now if you guys dont lose any speed in the turns, let me the first to say I have wasted a pretty productive 13 year career in this sport and I need to walk away, cause I'll never be able to do that:eekdrop:

Also look at the svl speeds, Pirate ran an impeccable race, however they averaged approx 8-10 mph faster than any SBI boat has this season. :lolhit::party-smiley-004:

No, what were saying is that we DO loose speed in the turns, which makes the numbers even more wrong lol

two identical laps in a row too!!! $hit's pretty consistant! lol

After reviewing lap sheets I'm more confused
 

Our fastest lap was number 3 with an average of 69.87. I didn't let off the throttle the entire race, so other than losing some speed in the turns I can't understand how we broke out. Our boat lacks the HP of most the other boats and runs very consistent, I would have at least expected to see us have the highest lap speed average during the break out lap???


Can someone with more knowledge of the matter shed some light on how to interpret these sheets.

Thanks

I'd like to know how some boats don't break out yet are half a lap ahead? Not trying to start sh!t just not sure I understand the break out rules.

Most likely , the course length of 4.6 miles is from pin to pin and not the true course you take when racing around the track .
If we change course length to 4.7 miles , then lap speeds drop by approx . 2 % or about 2 mph .

Just shows , hug the pins !

I believe this to be correct and the lap sheets don't have the exact length of the course.

So this is a mile / time calculation = a average speed. & has nothing to do with GPS breakout.

MD

Well correct me if Im wrong......but if this is pin to pin and we race outside the pin then everyone shoulkd have a SLOWER speed than their breakout speed due to your covering MORE ground than LESS. Which meens if your "ESTIMATED AVERAGE LAP SPEED " is OVER the class breakout speed then you BROKE OUT.

Is it me or this isnt adding up right??? What I see needs to happen is the GPS guy needs to give the Cheif Scorer the EXACT COURSE LENGTH via our GPS and then figure these #s out!! Guessing obviously isnt working!! Then all the numbers should be VERY VERY VERY close. And to say the course changes every lap is ludicrist. All the bouys are anchored as well as the start finish boat so there shouldnt be any variables.

OR......We start having an OPA OFFICIAL stand at the pier when we all get back and hand it over right then and there so all the scoring can start asap. No lending out a gps from one boat to another, we have spares to rent out to a 1 timer dont we?? If not, BUY IT!! We had to inorder to race. I see us going in the right direction but there seems to be to many "well maybe's". Lets sit down and make up some rules NOW so next season is a great one so NOBODY can b!tch.

I used to wonder the same thing, it comes with time. Seat time is everything, the start is everything and you cant make any mistakes.

The average lap speed as stated its based on course length so if you enter the length as 4.0 miles but the actual length is 3.5 the calculations don't work. Our currant breakout system however not perfect isn't based on lap times or distance its based on GPS speed over ground. So pretty much the lap times are just for us to look at not be scored on, just my 2 cents.

I wish there Was a way we could race using the same GPS we are scored on. Like the sbi system that you can watch and there isn't any questions as far as how much the OPA GPS and the actually GPS the driver is using?

Listen, we calculated out the lap times, because many have been asking.
The laps were calculated out based on a 4.6 mile coarse. Obviously, the distance is slightly off.
The intent was to give you an idea how consistant you are, or are not thats all.

Reason we dont use that system is simple. You can see if you have broken out. If you see a break out what is to keep you from just dusting the class for a cheap flag. Our system keeps you racing clean, because you have no idea what the outcome will be.

It's how fast you can get through the turns

Actually this is very simple, not all boats are running at the .9 mark 1/10 below the breakout speed at all times. It boils down to the consistency of the team meaning, what line did they take through a turn? How much speed do you scrub off in a turn vs what the other boat scrubs off through the turn?

First and foremost, as proven by the many posts on this thread, the avg speeds reported on the sheets are wrong. Honestly, I am surprised that it is still on the website as far off as they are.

In boat racing, no matter the org or anything, avg lap speeds are not an exact science and never will be. The only way possible is to have a fixed transponder at a point on the course, with transponders on each boat. ie start/finish boats and/or patrol boats are not fixed points as you still have drift, waves etc no matter how good they are anchored off.

Someone above mentioned "make up some rules". Thats great however, remember this concept about making rules. Rules means enforcement and enforcement means money. It takes money for more personnel as well as more money for the enforcement tools needed to enforce these new rules. Are we willing to pay more in equipment fees each year?, entry fees at each race? I mean the money has to come from somewhere. On the other token, I am not saying we dont need more rules, but we must keep in mind the money factor. I just think it would be nice to have the "unwritten rules" that have been already created installed into the written rulebook and obviously enforced. In 2008 Class 5 voted to be 30' ft and under with Bravo based drives only(no exceptions), I have yet to see it in the official rulebook. That should be step 1 before making new rules.

Once again I do not speak for Smitty or any official on the OPA staff, the above is my opinion and strictly my opinion only, carry on!!!!

A v

Sounds fair

Is this referred to as the "Trent Rule" from 07? lololololol jus playin boss
