Finnish fishing boat overhaul [Splashed 2017]

[mickyryan]

just awesome i would loved to been building a boat that big but i don't think my budget or yard would support it

 

[Red Herring]

Amazing Gm! That's really impressive. I'll send them over, hard to believe he could need anything else. Thank you!

 

[Red Herring]

Thanks Mickyryan, I really hope I managed to find the golden middle ground when choosing this hull and it's size. I wanted something that can handle our weather 90% time. I just thought of a simplified rule for this when it comes to the Baltic sea: rideable conditions 10% per m so a 5m boat is rideable 50% of the time Many told me to get a 12m , but the draft and size starts to affect shore fishing and getting in bow first.

 

[Red Herring]

What do you think, will I fry the pump like this?



Pumphouse coming along.

 

[mickyryan]

you know it looks so much bigger then 30 ft lol i think a 30 would be perfect if i could afford dock fees along with the fuel :0

 

[Red Herring]

Oh, that's a waterlock/muffler for the wet exhaust. There's about an inch in between the shower sump pump and the exterior of the tube. Not sure how hot it will get at worst.

I feel it looks like a tiny cartoon skiff with those huge Princesses behind it Our slip fees are minimal since the boating season at a minimum is around three months, at best maybe six.

Just some qiick info I found on temps. You should be fine with temps @ 120.F. Also some come with built in alarms if water restrictions occur.;

"In the past, many boats used a ?dry? exhaust system, in which the exhaust gases were transported to outside the hull without any form of cooling. The resultant hot exhaust pipe had to be thoroughly insulated, but even so, it produced a tremendous amount of noise. However, reduction of exhaust gas temperature to about 40? or 50?C (104?F or 122?F ) can be achieved by injecting the engine cooling water into the exhaust line. This is how a ?wet? exhaust system works. In addition, the typical diesel exhaust smell is also considerably reduced. A further major advantage of reducing the temperature, is the fact that all exhaust components downstream from the engine outlet can be made from rubber or synthetic materials. This permits greater design sophistication and weight reduction and ensures freedom from corrosion."

Thanks Kcassels, while trying to figure it out I found a post by someone who used a Whale Gulper to circulate boiling water in a hot tub. So it all should be good.







Pumphouse almost done. Still need to fit in one pump underneath the shaft and the seacock in the corner after exterior paint. It's a bit too crowded, but at least everything is in one place.

 

[Red Herring]

The oh-sh*t pump is in its place halfway down in the bilge. It's so narrow that only the supersub would fit, built the crude tray/box for testing of the pump. This is the one with a bilge alarm attached to it and I'd like to know if it's working for sure.

 

[Red Herring]

I will eventually exchange/supplement this one with a engine driven clutch pump, but at least for now it'll have to do.

 

[Red Herring]

Still waiting for the panel and grinding in the meantime, since I had time to think I got to the subject of exhaust and bilge-alarms. I ordered a couple of waterproof snap disc thermostats from your side of the pond, but would still need two different buzzers. One for the exhaust alarm and one for the bilge pump mentioned a few posts back.

I'd like to keep this really simple and my thought now is to have one continuous beep for the bilge pump and one pulsating one for the exhaust (or the other way around). I've found some really loud (+100db) pulsating buzzers that are waterproof as well, apparently used for tractor reverse alarms, but still have to find a similar one with a continuous beep. Any ideas where to find one?

Hoping to install them inside the steering console, there's a door in the back which has a vent that should let the sound bounce around nicely.

 

[Red Herring]

No Title

Hmm, now I found these. They're continuous though, so now I'm actually reading on how to make one of them pulsate. Seems more complicated than I thought.

 

[Teamster]

Is there a way to tie a light into the buzzer for visual recognition??

 

[Red Herring]

Yes, and there's alarms with both sound and leds integrated. That's one solution of course as well, requires another dash panel though.

 

[strokendiesel002]

Man Red, Your work is truly impressive! Thank you for documenting all of this. It's also great to see the teamwork that has come into play

 

[charleso]

Sir, all I can say is WOW!!! You have a wonderful boat. I hope to see you enjoying the fruits of your labor in the very near future.

 

[Pusher]

Could you put a turn blinker module in line with one of the constant alarm buzzers? Seems like a cheap and easily replaceable part if it would work.

 

[Red Herring]

Not a bad idea at all, I'll check into that. All that soldering and resistors started to feel a bit too much.

And thanks for the encouragement, very happy that it's getting closer and closer. Can hardly wait.

 

[Red Herring]

Apparently the oscillation frequency is linked to the circuits voltage draw, so with a small buzzer it might be undiscernable from the one with a continuous sound. But I'll get my hands on one and test it, it's a perfect solution if it works.

 

[Red Herring]

A led blink relay for motorcycles could be it, works with loads between 0-30W so maybe the 350mA of the buzzer would work.
