Connections of Seabass believe he will be a "stronger horse" when he has a second crack at the John Smith's Grand National in April.
Pat Glynn, who bought the stayer as a foal and heads the Gunners Syndicate that owns the 10-year-old, feels he is physically tougher than last season, when he was third behind Neptune Collonges in the Aintree showpiece.
Seabass, trained by Ted Walsh, has also had a lighter campaign than last term and was having just his second run of the winter when third to Roi Du Mee in the Bobbyjo Chase at Fairyhouse on Saturday.
"We're very happy with him, he's 100%. That was his last run before Aintree," said Glynn.
"He's a year older and a stronger horse this year. He had five runs before he went to Aintree last year and he's just had two this year.
"We've just got the one big target, but you do need a bit of luck at Aintree. Last year we thought he peaked a bit too soon, but he did run a good race.
"It's a pity the race wasn't in February when he was in top form, because he'd run in November, December and January as well as February."
The trainer's daughter Katie Walsh became the first female jockey to be placed in the National when riding Seabass last year.
She could again be in the plate this time, although her brother Ruby will have first choice and he has other possible mounts, including On His Own and Prince De Beauchene for trainer Willie Mullins.
Glynn added: "We don't know (about) the jockey yet. Ruby has first choice, as Ted always says. Katie rode him last year and she knows the horse. We'll be happy either way."
