Welcome to the swarm, and congratulations on buying TOP! Assuming you bought it that is... ( I see that it has been sold); if you didn't buy it, then please ignore the rest below....
This Forum was once a hive of activity, but these days hardly any of the Mossie sailors post here anymore, because they are all on the FB group page...https://www.facebook.com/groups/126390337427802/#_=_
It is a closed group, but if you are a Mossie sailor, they will let you in.
I apologise on behalf of the swarm for not responding to your questions about TOP, but that would be because hardly anyone comes here any more, not because we don't want newcomers, we do!
The Mossies keep a register of all known boats, and 1221 is not currently on it, so it would be good to get it added.
Good luck with TOP, and if you need any help and advice, plenty is available.
PS Glad you bought TOP; I was trying to get my stepson interested in it, but he wouldn't buy it.
