It is Mandatory that cut resistant clothing “with equivalent properties to Kevlar 29 fabric be warn by all participants in all T class boats. For 2012 Sleeves must be worn. For 2013 both Sleeves and pants must be worn.
19-B-2 (503.01)
Every boat must be fitted at the bow with a towing eye, One or two oars or adequate paddles, adequately secured and stowed, so that
they are immediately available, are to be on board. Every boat must have adequate bouncy to ensure that it floats in case of an accident. This buoyancy shall be equivalent to a volume of 0.055 m3 of foam per 100 kg. of boat weight. If a reinforced cockpit is fitted, at least one half of this volume must be securely attached to the cockpit structure. Any foam is to have a maximum density of 30 kg/m3. The floatation provided by the airbag is not to be included in the calculation for required floatation.

Fuel

19-B-3 (508.06) – Additives

19-B-4 (508.08) – Random Testing Of Competitors’ Fuel
1. Fuel samples taken at random from competitors during the event will be tested at the race venue, and may also be chemically analyzed afterwards in the laboratory. The organizer must seal the sample of the fuel in a fuel approved can.
2. The entire installed fuel system may be dismantled, removed from the boat and inspected.
3. Gasoline supplied by an organizer will be tested at the start of an event to establish its test device value.
4. In the event that the organizer does not supply fuel and the competitors bring their own, each competitor’s fuel will be checked. This will be part of the pre race fuel test.
5. At an event where the competitor’s fuel is used, it will be the competitor’s responsibility to ensure that at least one liter of neat gasoline is always available for sealing as a sample.
6. The presence of illegal fuel at any time will result in the driver being immediately disqualified up to that point.

The maximum length for T850 is 4.60 m (15’ 1”)

The maximum allowed ballast weight is 10 % of the specified minimum weight for each individual class. The ballast must be on the inside of the hull.
1. The minimum weight mentioned here above is the weight of a complete rig weighed directly after the race including driver, personal safety equipment, and residual fuel but without residual water.
2. Measurements are taken while the boat is ashore
The length must be measured as the overall length of the hull between perpendiculars at the foremost and aft most
rigid part of the hull. An extending parts, rubbing
starches; fenders, stabilizing and trim tabs and rudder are not to be included. The width of the boat is measured at the widest part of the hull.



19-B-31 (553.01) – Machinery
An outboard motor is a mechanical propulsion assembly, which can be removed from the boat in a single unit, complete with its transmission and which does not transmit
its power through the hull at any point. The motor thus removed and placed ashore must be capable of being started,
fed by its 25 liter fuel tank.
The mounting supports fixed to the boat, the control levers and the tachometer with its connections, the battery with its conductors and the fuel tank and fuel lines do not form part of the motor.
The use of power trim is recommended for all T750 and T850 boats.
For all T classes, the centre of the propeller shaft (measured at the centre point of the rear end of the propeller shaft) shall not be above the bottom of the boat measured at the lowest point of the bottom. No design of the hull, by fins, keels or convex shaped bottom to obtain a higher engine position is allowed. For boats with power trim this height will be measured with the propeller shaft set parallel with the bottom of the boat.


19-B-32 (553.02)
To be homologated as stock motor, an outboard motor must be sold and advertised by an industrial firm as being manufactured in standard production series (that is to say with all parts interchangeable and with identical dimensions, weights and materials) for the propulsion of boats. To be eligible for homologation, a minimum of 1000 units must have been built and assembled, certified by the manufacturer to the National Authority of the country of origin.

I like my rules
Show up
Race
Have fun
And No Whinning!!!
You win nothing its just for fun and bragging rights thats it..

It's also about having races. The days of the Wild Cat NO INSURANCE local races are over. In order to have race sites we must have INSURANCE. We get our insurance thru CBF/UIM. The INSURER insures us based on our CBF RULES. That is the reason why there is a procedure in place to set the rules and review groups at each level within CBF and UIM. SAFETY IS MOST IMPORTANT. APBA lost their insurance provider in 2012 because they did not follow the rules. APBA were lucky to find another provider [at a much higher cost] to insurer them.

What are the rules for Drag boats 110mph plus , Feh 100mph plus an D mod 80mph
as long as we follow there guidelines for safety , barriers, wrist bans ,cut suits etc is for insurance!

There are separate class rules for each class and there are overall site and general safety rules as well. ALL classes are now under watch. Getting T back was not an easy process. We were very lucky that T Class was a World UIM class with a long history to reference. Most of the rules above came from the UIM rule book. I did not make many changes to the original . I did not want to put up any red flags. I did make some changes last year. WE CAN! make rule changes if there are some rules you don't like. The CBF group reviews them at the annual meeting. They will agree, disagree or offer an option. It is the process. Working slowly avoids the risk of having CBF reject the changes. The size of the T boat class is very important to TORC and CBF. We have a very good product.

There are rules and there are rules !
First it is not unusual for racers to be DQ’d because of rule violations Happens a lot. Especially at top series where there is major competition.
We don’t see it at this level because in most cases it is an also ran that broke the rule[s].
So why DQ a pack runner and reduce the boat count?
The top racers can win at this level without breaking any rules. We know who those people are.
They have earn respect. They would not risk losing this respect by cheating.
The bigger problem is the newbie who doesn’t understand or have the experience. They follow advise and do what others tell them. They get frustrated and dwell on any negative they see. It’s human nature.
We have a lot of new people in T. I think the best approach is to remove the negative by demonstrating that it is important to follow the rules and that those that do have more success that those that do not. Plus they know they are legal. The infractions done to get “ an edge on the competition” are costly and in my view take away from other things that you should focus on the improve your results.
If you can’t drive you can’t win.
If your boat doesn’t handle..you can’t win.
The set up and your prop choice will make a more sufficient difference that any engine or fuel mod you make.
You must know your limitations. Some people are just better..period!

how do you measure the boat depth? 1'3"

It is the measurement from the deck gunal line straight across down to the bottom of the boat. You do not need to count the floor which could be 3 inches or more above the actual bottom of the boat. Some racers actually sit on the bottom of the boat on a foam seat.

my plan is too cut down a 1988 15' baja too 13-14',, im worried about it being deep enough.
