Billings smit rotterdam structure help

[Riotvan88]

Hello 

 

I'm trying to fit a raboesch 108-03 bow thruster on my billings smit rotterdam kit. The problem is that the forward hull frames are in the way and would need some serious cutting to make it fit. 

 

As I see it the way would be to cut frame 11. The cut will need to be down to the yellow line and I'm wondering if this may cause problems? 

 

Has anyone got any advice for fitting this kit with a bow thruster? Thanks

There doesn't appear to be much of frame 11 there now.  I would plan to reinforce both forward and aft edges of the joint of frame 10 to the hull planks with epoxy - fill in the gaps.  As this is obviously a r/c boat and the outside planking has or will be fiberglassed I would think about a layer of fiberglass on the inside of the hull between frames 10 and 12.

 

If the interior of the hull has already been covered with epoxy or resin the joints of frames 10 & 12 might already be strengthened with the application of resin or epoxy making the joints stronger than they appear.  And even the addition of fiberglass might be overkill.

 

Either way take the frame down as low as you need.

Kurts advice is absolutely spot on.  Just remove as much material as you need and fit the thruster.  What a lot of builders do is then make a false very low bulkhead and then back fill the entire void with epoxy resin.  Here's a couple of pictures of the thruster that I fitted in a Fairmount Alpine which didn't need that much backfilling but I could of completely filled the space if I wanted too.  I hope that this helps.
