Police say they are "satisfied" that there are no people missing after a boat was found adrift close to the shore in Colwyn Bay.
It comes after RNLI Llandudno said a search for casualties in the water was "inconclusive".
A lifeboat was launched at 7.20 am on Saturday 18 to investigate a 20-foot cabin cruiser abandoned in the bay, which was seen between the pier and Porth Eria.
North Wales Police thanked members of the public that came forward with information with regards to the circumstances of the “Phoenix Hardy” boat, saying the information provided generated a number of enquiries.
A spokesperson for the Maritime and Coastguard Agency said on Sunday 19 that the HM Coastguard worked with North Wales Police following a report that a vessel had washed ashore.
It said that while it was "reasonably" confident that all four men onboard had got off safely, it carried on the search with the police until it was satisfied that was the case.
In a social media post on Saturday, RNLI Llandudno Lifeboat had said: "At the request of HM Coastguard Holyhead the ILB proceeded to conduct a search in the bay to ascertain whether unknown casualties may have entered the water."After an inconclusive search the crew returned to shore to report to the waiting Coastguard and North Wales Police.
"An attempt was made to refloat the cruiser with a plan to tow it to Rhos Marina. However, this was unsuccessful, at which point the ILB was stood down and returned to Llandudno Lifeboat Station."
Enquiries continue to understand the circumstances that led to the boat being washed ashore.
