The reason all of the applicants’ ASA certifications are not on the IPC is because the IPC essentially is saying that you are certified up to at least the 104. Charter companies mainly want to see that you are bareboat certified in another form than the log book.
We keep the IPC streamlined for every applicant. We recommend taking both the IPC and your ASA log book when traveling. Please check with your charter company beforehand if they will accept the IPC.
