2009 Rules

Green  highlighted items are updated rules for 2009

RACE RULES

All classes will conform to NAMBA rules except for below listed club rules.
All classes will only be run when the 3 boat minimum is met

A race is considered "official" when no less than five club members are entered and at least two club officers are present.

All preliminary and final heats shall conform to NAMBA course size and laps. All classes will go clockwise turning right except for 1/10 Scale Hydro which will turn left. (counter clockwise)

Each race is started with a 5-minute audio countdown, with the race starting as the clock reaches zero.

All boats are required to be in the water by the 20-second mark of the countdown. Any boat not in the water at the 20-second mark will not be allowed to start.

All boats are required to be up and moving by the 10-second mark of the countdown. Any boat not running by the 10-second mark will be penalized one lap.

All boats must circle the center buoys of the front and back stretch but cannot pass the back centerline buoy before the 10 sec. Mark.  Boats are to establish lanes by the time they reach the center buoy between turn 3 and 4. Lanes will be held as boats cross the starting line.

Jumping the gun is a one-lap penalty. (Jumping the gun is crossing the Start/Finish line inside the 5-second mark but before the clock reached zero). Crossing the line before the 5-second mark does not qualify as a start, the boat must still fully circle the right hand turn then make its start.

Damaging or missing a buoy is a one-lap penalty.

If your boat goes dead in the water you are required to alert the other drivers immediately and state the location of your boat. Example:" Boat down left turn entrance pin".

RACE DIRECTOR AND CORNER JUDGES HAVE THE FINAL RULING ON ALL INFRACTIONS

Reference NAMBA rules for electric competition for further information.

RACE POINTS

Points are awarded per heat as follows: 1st-400;  2nd-300;  3rd-225;  4th-169;  5th-127;  6th-96,  7th 72, 8th 54, 9th 49  Did Not Finish-25  (7th, 8th and 9th will only be raced in Cracker Box and "N1" Mono)

Points do not transfer from one boat to another, except a driver may choose to transfer to an identical substitute hull.

The season point’s championship will be based on your point totals for eight races. (You can drop your lowest three races on a standard race schedule)

Awards will be given to the top finishers in season point totals at the final race of the year.

Points are accumulated on boat and driver together as one. No substitute drivers are allowed.

Points awarded in consolation races will count toward season high points at half value: 1st -200;  2nd-150;  3rd- 113; 4th-85;  5th-64; 6th- 48. The consolation heat winner  has the option of dropping the consolation points and becoming the 6th boat in the final “N2” Sport Hydro Class race.

BOAT APPEARANCE AND DESIGN

All "N2" Sport Hydro participants will be required to build and trim the boat as closely as possible to the full size version.

All members will be required to produce a photograph of the model boats counterpart if any questions of authenticity arise for 1/10 and “N2” Sport Hydro.

To be eligible, the real unlimited has to have actually hit the water and run.

Effort in scale realism is the desired attitude in "N2" Sport Hydro and "P" Sport Hydro, 1/10 Scale Hydro.

Accepted entries are "O" Sport Scale boats from  Electric Thunder,  DPI,  Dumas,  MRP,  Hobby Lobby,  Maus,  Blew By You,  Bandit Boats and scratch built boats and Hydro Marine.

Modifications to the ride surfaces are allowed providing they do not alter the deck aesthetics.

Oversized canard wings or horizontal stabilizers are not allowed.

Clear plastic panels are allowed in canard styled boats to fill the area between the canard wing and the leading edge of the ram. Clear plastic hull additions in any other application are not allowed.

Final determination of boats qualifications will be made by Puget Sound Fast Electrics officials.

GENERAL RULES

Trying to get boat back on plane during a race is allowed providing that it be done in a way as to not interfere with any other boats on the course, if possible. Try to get to the infield or off the course if possible, missing a buoy however requires one extra lap. If boats are approaching remain stopped until it is clear to proceed.

There is no excuse for striking a dead boat and it will disqualify you from that heat as well as create an immediate deduction of 300 points from your score for the day.

A driver may stop a heat if he feels his boat is in danger of sinking. However the driver who stops the heat is not allowed to restart that heat.

All drivers are required to carry at least two sets of crystals, frequencies are determined by club seniority. We use a frequency pin system which requires a pin be attached to your transmitter at any time it is turned on.

Frequency pins must be returned to the pin board when not in use.

All drivers are required to count their laps aloud as they complete them so the officials will hear them.

Leaving any garbage or litter on or around any race site will be considered unsportsmanlike and will be penalized 500 points.

Striking any water fowl at any time on race day will disqualify a driver from that heat or the next scheduled heat, with no points being awarded for that heat.

Drivers are not allowed to touch their boats once they have been placed in the water after the 20-second mark and during the duration of the race unless "officials" have given permission to do so. Permission is only given prior to a start of a heat race.

 

DRIVING RULES

 Driving rules are simple. Maintain your lane and leave enough room for the other boats on the course.

All boats must circle the center buoys of the front and back stretch before entering turn 3. Boats are to establish lanes by the time they reach the center buoy between turn 3 and 4. Lanes will be held as boats cross the starting line.

A boat must have a 3-boat length clearance (approximately 6 feet) in front of or behind another boat to change lanes. You cannot cut off another boat at any time

Racing with respect to others equipment is desired. No one wants to see damage to boats or equipment.

 

Penalties will be called when a driving infraction results in an accident. A penalty deducts 300 points from the season total and no points will be awarded for the heat in which the penalty was given. In addition if the penalty requires restarting a heat you are not allowed to start. Club officials or their appointees only can call penalties.

The 300 points will be given to the boat/driver that was hit.

Penalties may be questioned but are the sole responsibility of the Officials.

 

Boat registration
 Each club member may have two "N2" Sport  Hydro, two "P" Sport Hydro and two 1/10 Scale Hydro boats registered at any time.
A boat registration is the right to race a specific boat under the Puget Sound Fast Electrics Model Boat Club. This is done to avoid duplication of boats raced.
A boat is registered by mailing your request to the registrations officer—Club Secretary—
You must include 1.) Boat Name 2) Year of the boat #)  Boats are registered on a first come basis.
At season end you may keep your registration or pass them back to the registration pool.
At any point a member may throw away a registration freeing up room to register another boat. The discarded boat will be placed back into the registration pool. Remember, only two boats may be registered at one time in N"2" Sport Hydro, "P" Sport Hydro and 1/10 Scale Hydro.

DRIVER AND BOAT QUALIFICATION
Every new driver must qualify themselves as well as their boats for competition.
To qualify a driver must make a flying start within 5 seconds without jumping the gun. A driver must also run 4 laps, 2 on the inside lanes and 2 on the outside lanes under control.
A Puget Sound Fast Electrics official will determine a qualification.

Spec SV27 Class Rules

 
This class is a spec series for the AquaCraft SuperVee27ฎ (SV27) RTR Brushless Mono in its stock form.  Only a select set of well defined modifications will be allowed.  The boat will otherwise remain OEM stock.
 
Spec SV27 races will be held as either a standard 5-Lap Sprint Race or a 10-Lap endurance race. The hosting club shall announce the official race length prior to date of the race.

 

 Allowed Modifications:
The SV27 must remain in stock form, using only OEM parts as delivered, with the exception of the following allowances:
  1. Factory flex cable assembly and motor coupler may be replaced with any .150” Flex cable assembly and appropriate motor coupler.  The distance from the transom to the propeller shall not be altered.  Motor output shaft may be trimmed to facilitate installation of motor coupler and to increase coupler to stuffing tube clearance.
  2. Material may be removed at the forward end of the strut housing to eliminate interference with the transom, but no further aft than the leading edge of the strut’s vertical mounting bracket.
  3. Holes in the stock trim tabs may be opened up to allow tabs to be aligned flush with the bottom of the hull.  Alternate trim tabs may be fitted provided they serve no other purpose and that the wetted area does not exceed 33mm (1.3 in.) in length by 29mm (1.14 in.) in width.  Alternate tabs may be adjustable.  Alternate tabs must be mounted in the OEM location and have the width of the wetted area centered on this location. 
  4. Stock turn fin must be retained unmodified, but the leading edge may be sharpened.  No modifications to the mounting bracket or bracket location are allowed.  Additional fin is allowed on the left side.
  5. Stock rudder may be sharpened and water cooling hole may be cleaned up to improve cooling.  No other modifications to rudder are permitted.
  6. Motor Water cooling jacket may be replaced.  Water cooling outlet may be modified or replaced.  Water cooling tubing may be replaced.
  7. Receiver and transmitter may be replaced. An FM Radio package is recommended.
