A guess might be that the Yacht that once belonged to Mr. Albert Wood, the owner of Bodlondeb (then a mansion). He definitely had a large private Yacht that was moored in front of his home. Whether it is the same one as in the photo, I couldn't say. His Estate was sold in 1936 after he died.
The only info I could find about his yacht says the following - makes no sense to me but someone might know what it means:
Wood, Albert, I
Bodlondeb, Conway, North Wales.
Ang.-HigV~Mer.-St. G.-Tm8.-WeL
8. Falcon 16
8. Manya 148
