Mein neu Schnellboot! An ebay purchase, that didn't need much, but had never seen water. It's about 1 metre long.


'Sea trials' have proven that it sits right , has a good turn of speed too.


Only one issue- on turning it leans hard . I was wondering how to counter this- more ballast, less clumsy steering (the current option!), or perhaps reduce the size of the rudder ( not that it seems too large) . I could also reduce the amount of rudder movement range..


One thing that did make me wonder was the Schnellboots developed into three rudder set-ups- the outer ones looked like small stabiliser fins . I was considering adding these outer ones  as fixed fins.


What does everyone else think?

Hi Paul-H,
When it comes to putting this kind of dynamic issue of the boat as a theme, I just personally think you had better show the symptom by something like a video to have the MBM members understood more clearly in order to get many useful comments from them.. ..

The video itself will tell all that the boat behaved more precisely and securely with less words...."Seeing is believing"...

Good luck for improving the boat.!!!

Hi there


Under normal circumstances, long thin hulls - such as destroyer hulls and the one you have, do tend to lean into the turn rather alarmingly at speed.  This is just the nature of the hull - the lean may be slightly modified or reduced by adding a stabiliser of some description or by adding more weight as low as possible in the hull.  You will possibly find this will have less effect than, let's say, you being less aggressive with the steering    .  To be honest, if it were me, I wouldn't tamper with this lovely model.   It looks as though it may have been made from the free plans which were drawn by Vic Smeed and released in December 1961, in a Model Maker issue.
