Backup in case 'mains' one packs up on boat or I get a dunking. Also I do abit of rag and sticking and overshot a mark, ended up with 3rd place, now know where all the marks are.
Very small decent bit of kit everyone who plays/sees it thinks its great.
I got mine from maplins who seemed to be cheapest at the time. £129 incl delivery.
But a new Rib for xmas would be nice
oh and a Discovery3 to pull it.
