Spray rails for a 34" RAF crash tender

And the same to you Dave, 🙏 aged quite considerably since the last time I had my hands on an RC boat in the water so I'll let you know about that one later. Still at a bit of a standstill with all my builds due to the lack of usable workshop facilities, been banned from inside due to resin and sanding sealer fumes. 😭 Had a Metcalfe Mouldings The Scout kit from Santa but am still trying to decipher the instructions, building with styrene and fibreglass hulls is another new area for me 😰

Thanks Dave and Alsn for your wise advice and welcomes!
Happy New Year, I can see I'm going to learn loads on this site!

Rather depends on how good a sailor you are Shaun.

Meeting other objects, boats and the pond sides at speed always seems to knock bits off my boats 😰 Probably why you chose to use brass pins 😀 .

Happy New Year: 😀

Any attempt to blind me with science with regard to anodes is successful, however the pins can PING as much as they like cause the epoxy will hold the spray rails in place unless it is going to act as the cathode 😛

Happy New Year 😁

They wont rust Shaun, just act as an anode, disappear, then the spray rails will go PING 😁

Just one more whisky 👋

I hope the brass pins I used don't rust 😑

HI Eric
Welcome to the site.
The spray rails will help the model to plane but their main purpose is to deflect the water from the bow.

They run from the stern to bow and initially follow the chine until rising at the front.

There are many pics on the site that show this and I suggest you look at the Build Blog "Aerokits 46" Fireboat twin screw brushless conversion" by Paul Devlin. He has a couple of really good shots of the feature on his model that should help answer your question.

On my 34" model I used 1/8" square white wood epoxied in place. A fine drill and sharpened cocktail sticks would make a more robust fitting and hold all in place whilst the glue sets but I would not use metal pins left in place - they will rust.

Good luck. A build blog of your progress would be very welcome and perhaps you will post a few photos 😀
Live long and prosper

HI all, I understand I need to fit spray rails to help the boat plane, but don't have the first clue as to what they are It where they fit - any help gratefully received!
