"With the small fields, you're never quite sure what's going to happen, and he's probably not an experienced horse, but he got there on ability," Oulaghan said. "I left it up to Shaun and he handled it pretty well. It's good to win any race, but to win a National is pretty special.
"Hopefully he can come back and do it all again next year, but what we look at up north, I'm not too sure, so we'll get him home and take it from there when we see how he is."
Fannin was delighted to capture a win in the race after finishing runner-up on Mandalay 12 months earlier in his best result from five previous rides in the iconic event.
"This is the biggest race I've wanted to win, as I haven't had much luck in it, so it's very special to get it," Fannin said.
"He's probably not the best in front, as he gawks around a bit. He controlled the race throughout in a beautiful rhythm and he was just too strong at the finish. It actually helped him when they came at him entering the straight, as he went again and was comfortable at the finish.
"I was lucky enough to get on him last year and I thought he was one to stick with this season and it's paid off."
The victory was the third from just five runs over the steeplechase fences for the son of Mettre En Jeu, who has now won more than $119,000 in prizemoney from his 20 career starts.
West Coast is raced by the Williamson family from Twizel, including long-time jumps enthusiast Ron Williamson, and had long flagged himself as a jumper with ability, having finished runner-up to this year's Brierly Steeplechase winner Vanguard in a maiden steeplechase at Whanganui last year.
