Just browsing around and saw that no-one had commented on these.
The first painting is an amateur copy of a work by the celebrated Australian artist William Beckwith McInnes (1889 - 1939). He’s best known for portraits and figure studies, but he also painted landscape scenes. Here’s his original, together with an enlargement of the signature. It went to auction recently, with a presale estimate of $2,000 - $3,000, but an amateur copy would have little value.
The signature on yours beginning "W. B...." is either a coincidence, or a half-hearted attempt to hope that someone might confuse it with W, B. McInnes.
The boat painting, with the bizarre juxtapositions of scale and perspective very much looks like amateur work. The signature seems to be “Parnag Peterson” and “Parnag” is a not very widely used male Christian name originating from Armenia. Searches in artist directories don’t give any hits.
