The Seahawks lost their away double-header to Warrandyte Venom (87-77) and Bulleen Boomers (97-84) on the weekend to miss out on a men's division one finals spot.

The Mermaids' first season in the championship grade - the Big V's top tier - ended without a victory.

They finished their campaign with a 63-38 defeat to Bulleen Boomers on Sunday.

Mermaids coach Louise Brown said the 2017 division two champions and 2018 division one champions were better suited to division one.

"I don't think we have the cattle in Warrnambool to compete at championship level," she said.

"Every team we've played this year has had two imports. We were the only side without an import.

"If we stayed in championship level, it's something we would seriously have to look at. We'd need more sponsorship."

Brown said division one was the ideal home for the Mermaids.

"We're always competitive at that level, we'd always have a competitive team on the floor whether it's kids or experience," she said.

Brown is unsure what her role will be next season but is committed to developing the next title-winning roster.

"I still want to be involved whether it's playing, coaching or training with the girls," she said.

Brown said there was "a lot of promise" in the Mermaids' ranks.

"It's been a tough year for everyone I think but credit to the girls for never giving up," she said.

"They do everything (assistant coach) John (Wormald) and I ask, I can't fault them when it comes to that side of things.

"There's a lot of promise for the future, it's really bright. I am excited for the next few years."

Gainey said the word "unlucky" summed up the Seahawks' season.

"It was inconsistent. We had an import change a quarter of the way through the season, injuries and guys being sick," he said.

"It was a bit of bad luck."

Gainey said having decent minutes out of Josh Dean and Ollie Bidmade for the final double-header was what the Seahawks missed throughout the second half of the season.

"We showed small glimpses of what we could be," he said. "Having those two guys on court, they pose a threat and a physical presence as well. It definitely changes the way teams play against us.

"If we'd had them (playing) from start to finish this season in a perfect world, there's no doubt we would've been a top-two team."

Gainey will sit down with his family to discuss his 2020 season plans.
