Belper secured the Midlands 4EN title after they beat Skegness and fellow contenders Ashfield were beaten by Tupton.
Due to late pull outs and availability issues, Belper only took 16 players to the seaside.
Naylor had to start at 10, while wilmot was drafted back in at 9 and Innocent moved from 8 to centre.
The home side showed spirit and power as they pressured Belper in the first 10 minutes.
But, against the run of play Belper found themselves scoring first.
Following a well worked line out Dakin beat several players before setting free hooker Haines who raced over in the corner.
Belper extended their lead after good hands from Naylor, Smith and Stones put in Peverell, who finished very well to give Belper a 10-0 lead.
The home side soon hit back with a try that was converted and then a penalty to tie the scores.
During this time Belper were down to 14 with Dakin seeing yellow.
The home side could have extended their lead had they not been met by an excellent back row performance from Roberts and Powell.
Just before the half-time whistle a break away try saw Wilmott race over close to the posts, with Stones converting to put Belper back in control.
The second half saw Belper score five more times despite tough resistance from the home side.
The score minutes after the restart secured the bonus point and ultimately the game.
Haines broke before finding England in support, who in turn found Innocent to score.
Next to score was Peverell who finished very well in the corner before Innocent also scored for the second time after an interception.
It was now going well for the away side and Roberts managed to squeeze over from close range before the powerful Woodward finished things off with a thundering run.
After a nervous wait, Belper found out the title was theirs after Ashfield’s loss.
Belper hope this is the first of more successes to come this season with the first team in two finals and the second XV in a final of their own.
