about the performance

Of course. First day at the water this year she did 29.9 kts according to my gps. Here later at the season as growing is building and more shoes and bikinies pile up in the cabin, I will get 26-27 kts on a calm day; WOT and 2 persons on board. Cruising at 3100 RPM usually levels out at 18-ish kts.

This weekend first time WOT. Unfortunately no pictures made. i forgot about it.

 

But it did  47knt or 87 kph at 4400 =rpm.

The engine stopped there. After some more testing we found out that the

fuel line is too long or too small to supply the amount of fuel needed.

The fuel chamber between the fuel pump and the high pressure pump is empty quickly

after serious acceleration or at wot.  

So more tinkering to do. :giggle:

 

pictures next time.

Are you sure that is not a feature intended to save your economy? :giggle:

 

Undocumented  feature maybe but fuel economy 

is my project for next year. First run as fast as possible.

then Next year the plan is to add a Hydrogen generator. HHO generator

 

but there are issues to be fixed first . Like the swimplatform is leaking when the boat moved backward or when the 

drive touch the platform.

 

And there some trouble with charging the domestic battery. it takes to long or it does not charge. Dynamo voltage is 13.6-13.8V 

Charging from shorepower is perfect.

Summer season is almost over.  Took the boat for more than 60 hours. I cannot tell exactly because i did not always use both engines.

 

Cornering is fun because of the round hull. But like usual there are things to improve.

  • Battery protection. Sometimes shore power is gone for a few days and unfortunately the charger/converter drains my batteries.
  • Trim Tab. These must be bigger and needs a bigger angel upwards. At full throttle, it remains pushing the noise down to much.  
  • Dirt Water Tank. Replace the tank and i change the water tank to so i can finish the floor.
  • Generator. Check  the system because the generator stops after a few seconds.  
  • Trim sender is not working yet. Engine produces an engine fault on this.
  •  Make a step on the swim platform on both side. Getting inside from the deck is terrible. I am getting older. an the height difference between the deck en platform is to much for easy access.
  • Change the depth sensor. I cannot get it to work on my Raymarine e7. 
  • Solve some electric undocumented features. 
  • Increase the fuel line.

It never ends does it ?!

 

For the last time this season we wanted to make a trip of around 200 km. With a group of 30 boats we planned to go up the North Sea.

The weather was good. 25 degrees yesterday. Wind 1-2 bft (<11km/h) . Waves on the sea was less 1.7 meters. Ideal for some fun. 

We departed and still in the harbor i saw smoke coming out of my dashboard.

I quickly pulled my radio out but no sign of a fire. Smoke also came out of my air intake so my company opened the hatch. and yes there it was. My wiring boom  was on fire. 

Just a little but. After taking care of the fire, we try to figure out what caused it because i took the boat out for about 60-80 hours this year.

It was the fuel pressure regulator. It started to leak some fuel. The fuel felt on the exhaust and got hot. and therefore the plastic wiring boom caught fire.

So 250 meters and that was the end of the trip.

 

 

Just another point on the list to do this winter.:thumbsdown:

winter time means tinker time. 

I made a new display that is sunlight readable and is protected against water.

 

ofcource with CANbus(2x) with finally a boot loader. so programmable via canbus

but all electronics is now inside the box.

resolution is a bit better 800x480 instead of 600x480.

 

The rest is almost the same.

you see a lot of wires 

but it has about 10 inputs and outputs and there is a possiblity to connect to a camera

changes some screen next to the steering colums

Added reset button. when there are some electronic issue i can reset hardware without removing the power

And a red led give the state of access to the engines. Green when engine is enabled

screen1.png.dd55161000e8f70d845515b13dec0cc5.png

 

Added start and stop buttons next to the steering wheel

 

screen2.png.6a84cb0b2e4da0f71b41ce932f2e9b15.png

 

This remained the same

screen3.png.e571dd98f2383809a9f0591c7c0c14ea.png

 

Added my victron information on screen. when power is on, the voltage and current will also appear on screen

screen5.png.47cad3ce015917025016273a0bced3a6.png

 

Add added screen to dim the lights 

screem6.png.b2ee5c9d3e9ffc8a383b8154002c11e1.png

 

also create some gauges  it will all display the real degrees.

new pan tilt gauges

and new trim gauge

and a G force gauge just for fun

PIC_G.png.62a6326bee162cc8e8eaa91411f69ac0.png

 

there should become a power screen but i have now idea jet, what graphic to use.

The information i have is Volts, Amps , Watt and %charged. for all three batteries.

Shore current was not efficient on the dashboard but i have it on my ray marine display.

This thread is a fantastic read👍
What a cool and innovative project! 
How many hours have you used the boat now since the rebuild? 
You mentioned something about hydrogen earlier, is that still the plan? 
Also, where did you run the exhaust from the generator?

to Pero:

Thanks.  Just keep in mind  the first rule of technics: IF IT IS NOT BROKEN DON'T FIX IT.

I think i never stop changing things. electronics is an even great hobby as boating, maybe even bigger.

 

 

To kanalkapteinen

Also thanks. i used it not so much  as i would like but since  the launch about 300-350 engine hours.

I used the boat more but usually we go somewhere to the beach or forest which is just a few kilometres from here. The advantage of a small county. To make a trip through the forest is about two hours due to speedlimit(~9km) and then we hang around and get some sun.

Hydrogen is still the plan. But there are still a lot of things to do. like new trim tabs. 

And as for the generator. The original exhaust is just a little cap with two screws. a friend copied that but added a little piece of pipe to it so i could connect it with a flexible exhaust and a heat protection around it and drilled the hole thru the hull . between the registration number.

will be continued..:smiley:
