Paravanes boom position?

[Cold-smoked]

Hello Cold, definitely guys both ways, think of the stresses if you are turning across waves and you get some corkscrew motion, or following seas...?

Thanks, yes you are probably right.

 

[Cold-smoked]

Works great ! : )

I was mostly done and ready with the system on last thursday, ready for our off coast weekend fishing trip. We rented a nice cabin w/ dock near the fishing grounds. What is left to do is to fabricate the pole cradles/stoppers and perfect the retrieval system, paint, weld in a few reinforcements to the mast and so on. I used cargo straps as a temporary way to secure the poles in resting position.

It all works really well, even with only the poles out. It's like a new boat
I will replace the vanes' lifting plates when I get hold of some lead.

Total material cost is around USD $1200


Thanks for all the help, guys !

Thanks again, Larry !

Might want to make a spare fish just in case you loose one, but hang it on the cabin wall to view and enjoy. Looks like a piece of modern sculpture. Great job!

This is from this weekends visit to the fishing village. Lovely place. My boats yellow line will soon become green.

Thank you ! Yes, I sure will make spares

Looks good, Cold. Looks like you had fun too, which, after all, is what all this nonsense is all about.

Yes, my brother and both of my uncles are all ecstatic after this weekend trip. We had a great time, and the stabilizers made us feel a lot more comfortable and safer too ! We met people near the coast with new ~25 feet pilothouse boats who told us that they got scared by the waves offshore. We almost didn't notice those waves now with the vanes out.

Now I'm planning to go even further out to catch the really big cod during easter, with my dad and three brothers/one sis

This is my crude retrieval system. I haven't installed any 'hooks' along the gunwales yet, so I had to hoist the vanes up manually from the bow-area. I installed a clamp near the top of the poles to act as a hook/guide for the line. I whip the line a little to make it rest on top of the clamp. That way, the ss-ring stays out of the water. By using a clamp I can experiment a little and find the perfect position, so later I will weld on a piece of rod. I will also replace the retrieval line with a thicker line later on.

My uncles told me that it was easy to pull in the poles manually (while I secured them with straps), so I don't know yet what I will do about that. No rush. Last pic shows a simple and cheap block for the pole retrieval.

 

[Cold-smoked]

Cradles ?

One thing I haven't seen any close-up pics of yet, are the cradles for the poles and how you all secure them. Do you simply use the retrieval line to both pull and also hold the poles to the cradles ?

I made one cradle this afternoon, and tacked it into place. Curved cradles from pipe probably look nicer, but I didn't bother. The tips are slightly tapered to help guide the poles into position. I use pieces of splash guard rubber inside the cradles for damping. I also plan to use an adjustable toggle latch to secure the poles. I may have to weld on a rod w/cradles higher up on the mast later on. Now the poles retrieval lines are secured to the wheelhouse handrails, seems sturdy enough.

 

[Xsbank]

Don’t bother with the latches, I have my lines cleated off and the poles stay put. I’ll try and remember to take a pic tomorrow.

My system is working well, but I clearly have to modify the vanes. Sometimes it appears as they are behind the boat, so there is too much friction or drag from the lifting weights, and/or they are too light weight for the size (~300 sq in ). And this of course is not optimal nor efficient. I welded on some extra steel to the mounts to have more holes, but that doesn't help much either.

At 7 knots the cables from the poles are around 45 degrees down to the vanes. :lol:

CS: Our lead weights on our old ~300 square inch fish weighed 27lbs, 1/2 of a 55 lb down rigger ball. The first picture shows the fish traveling beyond vertical. The line at the bottom of the screen is 5.2' aft of the pole. So maybe not 45 degrees but they're back some.

 

[Xsbank]

My setup. That pile of line is the pole-retraction line. The fish just sits in its bracket.

 

[Xsbank]

The pole in its home. (sailboat next door).

 

[Xsbank]

Finally, a shot of the rigging retracted. Although you might be fooled, no, that's a piling and not on my boat!

Nice storage out of the way.

I mentioned earlier that I don’t use some of the rigging that came with my setup. It includes a galvanized ring of about 15 cm diameter with two lines attached. When we were in False Creek a couple of weeks ago, a former Canadian Coast Guard officer looked at my setup and he said without the ring and lines, the paravanes would travel too far aft for optimal efficiency. Of course the chain to the paravane would go through the ring, the longest line to the hause hole on the bow (each side) and secured on a cleat and The shorter line though the hause hole amidships. This would prevent the chain travelling so far aft. I will try that setup and see how it operates next time they are deployed.

That might be something you could consider and an easy fix.

You definitely don't want them too far aft because they are too close to the surface - if you roll suddenly parallel to a wave a fish could pop out of the water and that could be deadly.

Thank you, I have sourced some big old batteries now - so I just have to man up and get that lead melted and pour it into the moulds.

Thank you, your setup looks good and sturdy.

Thanks, so this then means that the upper part of the cable from the poles could be kept vertical - while the lower part would bend back ? Wouldn't this also bring the cables closer to the boat ? I don't think I have seen pics of anyone having this installed.

I’m not sure. I haven’t tried it yet. I will do so and get back to you on it.

Many boats run the poles way too high, loosing spread, and encouraging the fish to drag way back due to the length of the cable. Running the poles in a more horizontal position, as low as practical and safe, reduces cable length, improves spread, and shortens back drag.
Don’t think I’d want to tether the cable to the bow, that’s counterproductive, as mentioned above by Cold Smoke.
Finding the optimal adjustment for a particular setup requires some fiddling around with things, not the least of which is the throttle adjustment!

!

Thanks, I'm sure this is correct. But I worry about tripping with the poles too low, as mentioned by others - and the Transport Canada bulletins etc.

I guess we would be fine having the poles low like this yacht here.

Well, as this thread has gone quiet I'll make the announcement that we are starting .
Have galv fish, big springs if needed and big diameter, heavy wall ally tube sitting waiting surplus to another boat.
Access to mig and other gear and I have the skills.
Probably be a bit further aft than ideal, but its where substantial support is.

We are thinking 50x6 s/s flatbar to attach uphaul to running across the roof , under the solar panels and inline with a bulkhead and on top of a laminated beam.
Way oversize holes in the timber, filled with epoxy and microfiber and then re-drill to suit metal threads and screw in with liquid epoxy. (Did this on mainsheet traveller on previous boat with huge loads and not a hint of fail)

Beers and consultation with someone more knowledgeable next month.
Work to start when next on the hard in two to three months.

Proposed position in pic.
Other spot would be just forward of the funnel,which I would be happier with structurally, but apparently that may be too much wave action in the rough and increased chance of flying fish.

 

[Simi 60]

For your consideration, close enough to 50% mark and position of arm if done in the front location
