I’m getting bored with the routine and tried some 500m sprints today and evidently suck at them.

Any pointers on improving them? It's not a fatigue issue, I rowed another 9k afterward and felt fine.
Damper is set on 5 w/ a drag factor of 125.
welcome. If you are very aerobic/cardio rather than an anerobe then you may just be physiologically less suited. What was the time and stroke rate?
to be very fast at 500 you need to be able to be able to stroke fast (rates >35) and strong. You need to be fit too - it is not just a sprint but a middle distance "fly and die" for most. You will probably do better with a DF around 140 or above (some go to 160).
Some weight training for power will help and short hard intervals with longer rests.
This is an account written by Leo Young who has held the WR for about 30 years @1:10.5 (now shared with Phil Clapp and Loren Howard)
Note he did a lot of training at low drag but not on the day and it took him a year
To perform optimally over 500 meters, you need a base of good strength (developed primarily around lifts like deadlift variations, squat variations and seated rows, or similar movements), decent speed (best developed with very short max speed sprints on the erg at very low drag, with 2 to 3 minutes rest between sprints), as well as a very good maxVO2 (I had a maxVO2 of 7.6/L min at a HR of 158 and a weight of 90kg, prior to specifically building my strength levels and lactic power in my lead up to my 1:10.5 for 500m), but most importantly you need great lactic power as well as lactic acid tolerance.
The more muscle mass you have (I added 12kg of lean muscle to attempt my 500m), the greater your lactic power potential, which you then need to develop with max effort intervals on the erg in the 20 to 30 second range, with 5 to 10 minutes active recovery between intervals. Lactic acid tolerance (LATol), on the other hand, is then well trained with slightly longer intervals (e.g. 30 to 45 seconds) with shorter rest intervals (30 to 45 seconds), as well as also being effectively trained doing maxVO2/HR efforts.
20 to 40 minute low intensity aerobic workouts 1.5 to 2 mmol lactate) on the days in between the high intensity strength, lactic and maxVO2 workouts will aid recovery and actually indirectly help improve your lactic acid tolerance potential. However, avoid doing too many long slow distance workouts, which will have too much of a detrimental effect on your critical fast twitch fibers. It's critical to do no more than 3 high intensity workouts a week, which includes any strength training, maxVoO2, anaerobic threshold, lactic power, or lactic tolerance training. So clever programming is critical.
Do maxVO2 training by doing intervals at max HR pace (either 3 to 5 minute intervals with 3 to 5 minutes active recovery, or alternatively over 3 to 5 minutes build HR and pace to up around your anaerobic threshold or max lactate steady state pace and then sit at max HR pace for for 1.5 to 3 minutes, depending on fitness level), as well as doing some training sessions where you spend 15 to 30 minutes at your anaerobic threshold (AnT) or max lactate steady state pace (MLSS). A good combo AnT/maxVO2/LATol session is after a 15 minute warm-up, do a 20 minute effort where you build to AnT over the first 3 minutes or so, then spend 15 minutes at AnT/MLSS pace and then go to maxVO2 (max HR) pace for the final 1.5 to 3 minutes.
