I just read above that a boat was not insured and yet taking part in a club race - Hopw come ? I assume the rules are different at your club. At mine we MUST have insurance to be allowed on the water and if there is any damage, there should be a protest to determine fault.
I saw a similar incident on a Laser, an old one T boned my buddies brand new boat, first time in the water, "too bad, that's racing" was all he got out of it! To get a lawyer involved would have cost more than a new Laser so nothing was ever done about it.
That is also shocking, how can someone be so cavalier about it. My answer would have been "See you in the protest room", got proof of his fault and then got his insurance details etc.
Shocking !
