I'm the GM in our group and I came across an adventure the Margaret Weis' Firefly called Shootin' Fish... it's basically about the group performing a dirty boat race. Of course, it had the obligatory corrupt law officer/land baron, cut throat racers, and lots of gun fire. I just had to adapt this to Edge of the Empire.
In short, the group was hired to win a skiff race to save the orphanage and farm. They had access to a "used skiff" that would take some work to get up to snuff, but the party decided instead to buy their own that they could put on their freighter and use as a mule.
The race was to take place at a remote place on Tatooine, and the rules were simple... the first skiff across the finish line with at least three people alive won. It was expected to have lots of shooting so weapons were fine. Because they bought their own skiff, they short circuited some parts of the planned adventure, but thinking outside the box should be rewarded.
The race would go through rocky canyons. Then after a few miles, would enter a large underground cavern with glistening walls -- that turned out to be water. Upon leaving the caverns, they would race across the dunes. Rounding the last "turn", they raced across water evaporator farms. All told the race would take about 40 minutes (game time, not play time).
The group split up to handle different tasks. The pilot and mechanic found the skiff, reinforced the skiff and mounted a weapon on the skiff. The explorer and bounty hunter did some scouting work. They plotted out the most likely best route, and found a few places where it was likely to have snipers working for the other groups. They also discovered an underground lake of Alkaline water on Tatooine. The droid was working on upgrading items and doing general things to help the party. Everyone had some tasks to do.
The bounty hunter managed to get a job in town doing day labor in an effort to find out details about the other racers, and to find where their skiffs were. He expertly managed to sabotage several, and get the Jawa racers and the Droid racer teams to blame each other and that added a whole new level of entertainment.
Our droid and explorer investigated the underground lake and found an operation to purify the water. Believing (rightly so) that the land baron was the one behind it, they sabotaged the operation. This just added some confusion to that particular team, although how much, the party wouldn't know.
The mechanic and wookie worked on the plans for the race and working on ways to make sure they had some advantages. This resulted in numerous boost die during the race.
During the race, the explorer and bounty hunter were busy removing sniper threats by tusken raiders for the first leg. They didn't manage to get the snipers for the corrupt law officer/land baron, but they got other teams and not the party at this point.
The pilot made some awesome rolls and moved up through the ranks, and a few other teams had some misfortune. The crew on the skiff also managed to take out a few other teams through gunfire and their mounted cannon. When they got to the caverns, one of the barons teams and our heroes got into a fight with skiffs banging off each other and the walls. The fighting was tense, and after successfully taking out the other team members, the pilot managed to dodge the wreckage as it careened off the walls.
As the race was entering the second half, our explorer and bounty hunter regrouped at a stretch that was also a good sniping point. They managed to beat the other sniper team and removed that threat before the skiffs could get there. As they cleared the other team, a few skiffs that were 'cheating" started moving in with armed thugs. The skiffs lined up to blockade the other skiffs with the intent to allow their boss to continue unchallenged.
Our skiff took out the last of the goon skiffs and only had the big bad guy and his blockade between them an victory... unfortunately, they had the blockade between them, and they had a lot of guns. As the big bad guy was trying to go on to victory, our bounty hunter and explorer took the speeder that the other sniper team was using and rammed the skiff sending it into the sand.
About the same time, our heroes on the skiff managed to take out the rear blockade skiff and created an opening. Our pilot hit the dune and skiff and sailed past the line and moved toward the wrecked skiff. The wookie gunner targeted the big bad guy, and hit him with the mounted light blaster cannon... ummm... 50+ points of damage... well, the big bad guy was alive...
The party then went on to win the race. The town initially was celebrating, after all, they were under the corrupt control of the land baron. So the party won, but they also created a power vacuum.
The Black Sun is not happy... the big bad guy was one of them... it was an awesome session, took 5 hours, and was fun every minute. Every member of the party had something to do.
