PDA Edition of Tactical Programs (1 of 2)
The PDA edition of our tactical software enables users to view and control the tactical program (Force 4 or Offchart Racer) from a PDA they can put in their pocket ... This is ideal for small boats without a downbelow navigator, and allows all crew to monitor and modify instrument output and tactical displays from anywhere on the boat. As with all of our programs, ORPDA comes with its own charts and incorporates our detailed current models (available for all major US and many foreign venues).

The PDA edition for Force 4 is included without extra charge, and the PDA edition for Offchart Racer is available for an additional charge of $200. Offchart Racer is being phased out in 2007 in favor of new Advantage Level 2. Since this will not be available for PDA, a user will still be able to purchase the 2007 edition of Offchart Racer with the PDA Edition for a total of $900.

ANY STANDARD PDA SERVES AS A WIRELESS INTERFACE TO A LAPTOP THAT RUNS THE SPECIAL "PDA VERSION" OF OFFCHART RACER. INSTRUMENT CONNECTIONS ARE MADE TO THE LAPTOP, WHICH RUNS BELOWDECKS AND CAN BE STOWED IN A SECURE, DRY LOCATION. THE PDA DISPLAYS AND CONTROLS THE PROGRAM BY TOUCHSCREEN, WITHOUT ANY NEED TO ACCESS THE LAPTOP DIRECTLY DURING THE RACE.

THE PDA VERSION IS DESIGNED TO BE VISIBLE AND EASILY CONTROLLED FROM THE SMALL SCREEN OF THE PDA. IT CAN ALSO BE OPERATED DIRECTLY FROM ANY TABLET OR MID-SIZED LAPTOP WITH WINDOWS XP OR OTHER STANDARD LAPTOP OPERATING SYSTEM. ORPDA HAS ALL PRINCIPAL FUNCTIONS OF "OFFCHART RACER," OPTIMIZED FOR THE SMALL SCREEN.
IT IS ESSENTIAL TO AVOID CLUTTERING THE SMALL SCREEN. WITH ORPDA YOU CAN HIDE ALL CONTROLS BY CLICKING ELSEWHERE ON THE SCREEN. CLICK AGAIN TO BRING BACK THE MAIN MENU BUTTONS. CLICK ON A GIVEN BUTTON TO EXPAND OR CONTRACT THE ASSOCIATED FUNCTIONS. CLICK ON A RESULT FORM TO MOVE IT AROUND THE SCREEN.
THE VERTICAL ROW OF BUTTONS ALONG THE LEFT SIDE OPEN MENUS WHICH PROVIDE CONTROLS AND DATA DISPLAYS OF ALL PROGRAM FUNCTIONS. IN THIS EXAMPLE, THE "I" (OR INSTRUMENT) BUTTON EXPANDS TO SHOW MEASURED WIND, BOAT HEADING AND BOAT SPEED, PLUS TWA AND TWS COMPUTED WITH CURRENT CORRECTIONS.
CLICK THE "D" (DATA) BUTTON, TO ACCESS WIND, POLAR AND CURRENT MODELS AND DISPLAY PREDICTED VALUES AT THE BOAT LOCATION. IN THE EXAMPLE BELOW, CLICKING 'C' ON THE MENU EXPANDS DISPLAY TO SHOW CURRENT AT THE BOAT. CLICK THE "M" (MARKS) BUTTON TO OPEN THE MARKS MENU (AT BOTTOM OF DISPLAY). YOU CAN PICK A MARK FROM A LIST, DEFINE A NEW MARK, OR ACCESS A VARIETY OF FUNCTIONS WHICH APPLY TO A SELECTED (ACTIVE) MARK.
THE PDA HAS NO KEYBOARD, SO ORPDA HAS A SPECIAL FORM TO MAKE IT EASY TO EDIT OR DEFINE NUMBERS BY POINT AND CLICK. THE EXAMPLE BELOW SHOWS HOW YOU WOULD DEFINE OR EDIT THE LAT-LON COORDINATES OF A MARK.
CLICK "C" TO OPEN THE COURSE MENU. YOU CAN SELECT A PRE-DEFINED COURSE FROM A LIST, OR DEFINE A 'QUICK' COURSE BY POINT AND CLICK. ONCE A COURSE IS LOADED, CLICK 'FUN' TO ACCESS A VARIETY OF COURSE FUNCTIONS.
CLICK "T" TO EXPAND THE TACTICS MENU AND ACCESS THE LAYLINE, BEST TACK AND ROUTING FUNCTIONS. THE LAYLINE AND BEST TACK FUNCTIONS AUTOMATICALLY RECOMPUTE EVERY FEW SECONDS TO UPDATE THE SITUATION. BELOW, THE RED AND GREEN LINES SHOW WHERE THE BOAT WILL INTERCEPT THE CURRENT-CORRECTED LAYLINES IF SAILED AT THE INDICATED TWA ON THE PORT AND STARBOARD TACKS. THE BEST TACK FUNCTION USES MEASURED WIND AND THE UNDERLYING CURRENT MODEL. ALTERNATIVELY, YOU CAN ENTER CONSTANT VALUES FOR A "WHAT-IF" COMPUTATION.
