Longliner, sorry to be a smart arse, but i've seen how comprehensive nets can be! Have you seen the bottom of the Med - clean!!

Your a 'longliner', that don't do too much damage to the habitat (too many hooks does tho') Banning nets includes the accessories - fishfinders that are more sophisticated than navy sonars, GPS for spot on navigation etc.

It may sound twee but give the fish a fighting chance and they'll keep going for ever! Net 'em with sonar and pumps and they'll be gone before you can turn around; that method spells disaster for all! As is being proved time and again, so as I said ban 'nets' for a while (hey it don't please me either but something drastic has to be done :?: Ever heard of the Icelandic Cod Wars, that was drastic and sorely affected the British Fishing Industry - nearly closed it down! :?: But we survived - leaner and meaner but we did survive! So did Iceland and more importantly the FISH!

Chandler if I have to give up my 'fish and chips' for a short while to give the stocks chance so be it! Don't like chips anyway - potatoes being an American invention see!

 

Oh yes and ban amateurs too! unless they can eat it straight away! If they land they forfit the boat (harsh but it all helps)

not the sharpest tool in the shed, sometimes I make a mistake , on this site I want to publicly apoligise to all . I know you guys have tremendious expiriance in your fields ,and it is gracious of you to share , and you could have cut me to ribbons with your tonges ,but you didnt ,,,,,,,,,,,,sincerly longliner45

 

I hate to sound calculating an cruel. But lives are lost with the boats used today. They are only 'seaworthy' when their engines are running. If their engines should conck out, they are helpless. Once in a wave trough, they are easily capsized. There was once a trio of king crabbers, two of which whent belly up on the same day.

Modern fishing boats are no more designed for safety than their archaic counterparts. They are designed for their primary function. Catching fish. And catching more fish and at a faster rate, hopefully, than their competitors. All other concerns are secondary. Last one to the fishing beds comes home with empty holds.

Think of re-instating dory fishing in an age of satnav and good hand held two way radios. Would kind of cut down on the carnage, eh.

Guys, I hate to be a party pooper - hey I'm on your side here, but do you think you may have hijacked this thread....

 

You're right. This poor man only wanted to know if his sword boat would work and now we are doing a critique of the fishing industry. I'm starting a new thread now. I'll call it 'The future of commercial fishing?'. Hope to see some of you there. And we can leave this poor, gracious gent alone.

safewalrus,
What we need to get rid of are the Russian and Japenese factory boats, cleaning the oceans and packing it at sea as well.
I live in Maine and most of the fishermen are on 50-70 ft. boats. They're trying to make a living with nets, not decimate fish stocks. They also have very strict limits as to what and how much they can take. I's the big boats in international waters cleaning the fish out of the sea.

 

And that is absolutely correct!!!!!!!!!!!!

 

Amen to that but have you seen the Scottish boats with 'black' fish (over quota) alongside the Russian Ships selling the stuff direct to them - talk about 'cutting you nose off to spite your face'! and if they are doing who else is elsewhere - nothing like a bit of greed to show up the bad in humans is there! (I ain't saying they're all doing it, just a few, but 'chuck s**t against the wall and some of it sticks')

NOW LET'S LEAVE THIS GUY ALONE WITH HIS QUESTIONS ON HIS BOAT, all future fish type posts will be on Sharpii's thread!

 

From my calculations your boat will have:

31 mt of fish hold capacity (does that include ice),
38 mt of diesel, and
2 mt of fresh water.

That gives us a grand total of 71 mt. And this list is hardly comprehensive. What about winches, hoists, and other gear? In my method of guestimation, I like to calculate one mt of vessel for every two mt's of capacity (that does not include ballast, which mout be added to desired capacity). If this is not a gross under estimation, your boat would have to displace at least 107 mt.

With the largest engine you mentioned, that would give you less than 3hp per mt. With that, you might get 8 to 9 kts out of her, wide open in decent conditions. That's the bad news. The good news is that your range will be considerable. around 7,000 nm, by my guestimation (with a highly efficient diesel set up). And that can probably be stretched to 10,000 nm if you throttle back to, say, 6 to 7kts.

Is your boat going to be a 'long liner'?

Bob

 

Yes, shes gonna be a longliner.... It's been a nice long vacation from the forums. But Im still looking around for the boat designs to fit my needs. I scratched my sketches as there are plenty out there already made up with some mods and you're set to go. I'm currently looking at the Argonaut 65 by John Simpson Ltd. Just waiting to hear back from him. Has anyone come across similar designs and specs of her? http://www.metalboatkits.com/Argonaut/argonaut.htm
