Westcarr was hugely influential last season, scoring 22 goals in forty-three appearances and was the Reds top scorer last season.
New manager John McDermott was thrilled to have secured Westcarr's services for another season: "It was fantastic for us to have secured Craig for the upcoming season. He's an experienced striker who can finish and score goals.
"He scored 22 in a team that mostly struggled last season which was fantastic for him, it was a no-brainer for us and when we spoke he clearly wanted to stay. I explained to him the type of football we want to play and he was excited, it was perfect for all of us.
"I want experience at our core and Craig provides that for us, it's great we have him again for this season."
Westcarr was also very happy to have signed another deal with the Reds: "I'm delighted to have signed a one-year deal. It's exciting times here and I'm really looking forward to working with the Gaffer and the squad of players we have is very strong now and I can't wait to get going."
Smith (pictured) has re-signed despite suffering an injury-hit campaign last season and made just a dozen appearances, scoring 3 goals.
McDermott said: "On his day, he is the best winger in the league. He has had problems with his knee but he has been passed fit for pre-season training and the fact he is available for us means we have three very, very good wingers in the team now which gives us ammunition for the strikers.
"We'll have to search very far to find better wingers and I had a good look at Adam on Saturday when we started training, and he looks good and he needs a good few weeks in pre-season. He's kept himself physically fit and once he has games he'll have his confidence. He's an excellent player to have within the squad".
