John Cartwright is confident that young Hull FC duo Jack Charles and Callum Kemp can step up to Super League and answer the Black and Whites' call if required this season, with the duo already having 'a great knowledge' of the game.

The highly rated teenagers both made their first-team debuts last season, with Charles appearing 17 times and Kemp debuting in the final round. And while it was tough at times for all of Hull's young players, of which Logan Moy, Lewis Martin, Harvey Barron, Denive Balmforth, Will Gardiner, and Zach Jebson also featured regularly, the new head coach believes it will do them the 'world of good' in the long run.

Focusing on Charles and Kemp, who have already played together at scholarship, academy, and reserves levels, being just one year apart, Cartwright is happy to call on them if needed, with Aidan Sezer and Cade Cust set to start the season.

Speaking on the teenage duo, Cartwright told Hull Live: "They're really good young kids. They've got a great knowledge of the game already, and they're very skilful with good kicking games. They just need experience.

"We're doing our very best to get them games at the highest level that we can. They both played in a side last year where it was very hard for an inexperienced half in a team that is getting beat. I really felt for those boys last year, but the reality is that it will do them good in the long run.

"They know what to expect now at that level, the intensity, and they've got a lot more experience around them this year, so if we do have to blood them at some stage, I'm confident that they will be able to handle it."

Outlining the toughness of last season, a campaign that saw Hull win just three matches all season, Cartwright is expecting the duo to grow from the situation, particularly Charles, who was asked to front Hull in what was a farcical year of player departures and change.

He added: "It's really hard at the time; no one likes to lose, but you don't get to this level unless you're competitive. It's hard to put that responsibility on their shoulders; a half-back is responsible for a lot of things that happen on the field, no matter what their level or age is.

"Obviously the younger they are, the more you try and take away from them, but the reality is they touch the ball a lot, they kick the ball a lot, so they're in the game, and it was unfair of those boys to get that responsibility last year, but it will do them the world of good in the long run."
