Hello Peter,
What a incredible achievement ! Not only have you proved that it can be done. You also proved that a "poor person" can do it.
So this is not only a sub building achievement but also a mayor building management achievement.
I also have to congratulate you to make the point clear that a big sub is not always a expensive sub. On contrary it can be a very economic live aboard lifestyle you really pulled it off !
PS: it breaks my heart that you are going to focus on rockets in the near future...
Cheers
Wil
