Yet another new build Springer!
Re: Yet another new build Springer!
with video , of course.
I do like videoing stuff!
Now then... when you guys say the Springers like to submarine, you're not kidding!
The speed is much better but man! get to full speed and the tail lifts up and the front digs in! on the plus side, the washports work!
Treat every day as your last,, one day it will be.
This angle would give a downward thrust line coupled with the resistance of the bow wave and lifting the stern and so pushing the bow under!
It was quite alarming though!
Thats a good looking Springer.
I assume that the "inverted wing" profile doesn't help. Might actually generate some downforce ?
Just tow a 300kg heavy-lift ship.
At full throttle it still tends to dive. There's water coming on the deck but it is still safe to sail that way (although it looks weird).
So truck measure their speed in Knots?
I am a huge speed freak and this is by far the slowest thing I've ever built! my current fastest is hitting 100+mph! this Springer could be my backup rescue boat for when my fast one ends up on its back!
I thought that about the shape too and was thinking of building a traditional bow under the waterline???
I also have a bulwark all round and I deliberately pointed the section between the knees forward to help but it still floods the deck, the extra weight of the water drags it in deeper and I've been lucky not to send it down!!!
Springers are good recovery boats even without such a rig. The flat bow is very convenient.
What are people doing on their drive angles??? Is my downward thrust line pushing the back up and the bow into the water???
Has anyone tried fitting a traditional bow under the springer?
I have a feeling about it....???
Yes someone did de-springer a springer by putting a sharp front on it...er pointless exercise if you ask me , it wont be a springer. Remember what they are .. truckable pushboats. The variations of the topsides have spawned all type as you know but most people hesitate at going the pointy end bit. Just build a simple conventional shaped tug which a lot of people do having been introduced to model boating by the simplicity of the blunt bow. They weren't designed for efficiency BTW I was the idiot that tried the bulbous bow on springer, designated by some as "Arrow`s Knob" . Toesup had front foils under the bow, worse than the bulb Your raised bulwark is a better idea, I`ve got a couple with a strip of 90* angle sticking out front.
I wasn't thinking of a "pointy" bow, Just the part under the water... the part that pushes against the water..
I've been playing with boats for 25 years or more but I built a Springer because it looked fun, plus my daughter wanted a boat and this is a great start for her.
I think I saw your design. I say!
I was also thinking of putting a clear screen on top of my forward bulwark???
The "part under the water" i.e. most of the hull ? The answer is weight distribution. Waterline at rest should be an inch lower at stern. The V under the bow would be an interesting study, try a block of blue (or pink) foam and video the result.
I will move my batteries and go from there.
I think I'll try a simple mock-up....???
Ha! That did make me laugh!
Apologies for bringing upan old thread,i just wonderedif you could spare a little time to tell me your routine and technique for cutting your wood,in particular plywood for hull and the major parts?
Can anyone else giveme their techniques i mentioned??
