We completed our crossing from the Galapagos to the Marquesas on May 11, 2025!!!!
Here is the Sea XII sitting at anchor in Hanamoenoa Bay off of Tahuata Island.

The crossing, by the numbers:
- Days underway: 17
- Actual travel to Hiva Oa was about 16 days 18 hours.
- This arrival time though brought us into Hiva Oa after sunset, and the anchorage was crowded. We made circles in the ocean until sunrise. This added 6 hours and about 30 nautical miles to the trip.
- Total miles travelled:
- 3,005 nautical miles or
- 3,458 statute miles or
- 5,565 kilometers
- Total fuel burned:
- 2,450 gallons or
- 9,274 liters
- Efficiency: 1.22 NMPG
- Our efficiency would have improved by .12 to 1.34 NMPG if we didn’t have to run our generator due to the alternator failure
- Engine operation:
- We maintained 1,200 RPM for most of the trip which averaged out to just over 7 knots
- Every 2 days, sea state permitting, we did a “burn” at 1650 RPMs for about 1 hour
- For 8 hours on day 15 we increased RPMs to 1300 trying to shift our arrival time to be prior to sunset, but we gave up and shifted back to 1200 RPMs
- Generator use:
- Because our secondary alternator failed and the primary does not generate enough power to maintain all boat systems while underway, we had to use the generator daily to recharge batteries
- We ran the generator for 6 hours a day. This gave us enough time to recharge the batteries, run the air conditioning in the state rooms to cool the boat a little and make water.
- Maintenance underway
- We replaced 5 filters in the fuel polishing system
- We replaced the primary fuel filters for the main engine about halfway through on day 8. These filters looked pretty clean compared to those from the fuel transfer system
- On day 8, we slowed to idle and added half a gallon of oil to the main engine, just in case
- This engine does not really allow for testing oil levels while turned on. We didn’t want to turn the engine off while underway, just in case
- Driving Schedule
- We kept the boat on Galapagos time as we moved further west, this caused a little confusion for some of the kids who started to wonder why it was dark outside at 8am…
- Jamie was on shift from midnight to 5am
- Paul was on shift From 5am to noon (aligned with his work schedule)
- On some days, Hannah and Kathryn would take over for an hour or two in the middle of the day so Paul could take a break
- Dinner as a family was served at 6pm every day
- Paul would go to sleep from 7pm to 9pm
- Jamie would go to sleep from 8pm to midnight
- Paul was on shift from 9pm to midnight
