🔍 Key Concepts

• Load limits from the COASTAL DRILLER capacity charts or operating manual • How extending the rotary farther aft of the transom affects allowable load (moment/lever arm concept) • Differences between maximum structural capacity vs. reduced capacity at specific outreach positions

💭 Think About

• Locate the specific table or graph that lists rotary load versus outreach distance aft of the transom for the COASTAL DRILLER. What load is shown at exactly 40 feet? • Think about why the allowable load might decrease as the distance aft increases. How does this trend help you rule out answers that are too high or too low? • Compare the pattern of values at nearby distances (e.g., 30 ft, 35 ft, 45 ft). Does the change in allowable load between those points make any of the options unrealistic for 40 ft?

✅ Before You Answer

• Confirm you are reading the correct table/figure for the COASTAL DRILLER and for rotary load vs. outreach aft of transom, not a different limitation • Verify you are using the units kips and matching them exactly to the chart (no tons vs. kips mix-up) • Double‑check that you are looking at the row/curve for 40 ft aft, not a nearby distance like 30 or 50 ft that could mislead you
