Key facts
The checked approximation is about 45 minutes
DASTA and Pattaya City materials both describe the public passenger-boat journey to Koh Larn as approximately 45 minutes. The two government sources therefore support that figure as a rough planning reference.
The claim remains marked disputed because the materials are legacy sources rather than a current operator performance record. Agreement on an old approximation is not the same as a live guarantee.
Keep the figure attached to the public boat
The approximation belongs to the public passenger-boat journey described by the sources. It should not be transferred to every speedboat, charter, route variation or disrupted service.
No current fare or timetable is established here. Adding either would go beyond the mapped duration evidence and the deliberate Koh Larn hold.
Do not plan a deadline from 45 minutes
The supported companion claim says the approximation is not a current operator guarantee or live arrival time. Use it to understand the rough scale of the crossing, not to promise a connection.
A same-day plan still needs the current sailing in both directions checked separately. The duration answer cannot establish whether a particular departure or return operates.
Recheck the approximation before relying on it
Seek a current city or operator confirmation for the public-boat duration before using it in a time-sensitive plan. Keep the answer conditional until that check is available.
If the current source differs, use the current service-specific information and preserve the discrepancy rather than averaging it with the legacy 45-minute figure.
