I'd like to build a lobster trap puller and davit for the boat for next year. Since I'm way too lazy to pull traps by hand, i'd like to put together a motorized system of some sort. I have a motor with a horizontal shaft and was wondering if any of you guys had any thoughts as to how to go about either adding a clutch or reduction gears etc. Do I need hydrolics or can I get along without? I have no experience with these systems so any ideas are welcome.
thanks.

I have aa ACE Pot Puller.  We use them for shrimp pots in Prince William Sound.  A bit spendy, but i sure like it and it saves the arms when we are down 400 feet.  Craig F.

I need to get a pot puller!  I've dropped my 2 pots, each weighted with 4# of lead, plus 4# of lead on the line to 600' and have pulled them twice by hand.

so far I have a double ended mandrel/axle withs two pillars for 50 bucks and a 6" pulley for 20 bucks.
I need a 3/4 bore smaller pulley for the motor shaft, a v-belt, and a capstan for the working end.
The whole system should cost about two hundred and fifty excluding 5hp motor.
I hope that the 6" pulley slows things down enough to be effective.
all said and done it's probably cheaper to buy the ready made electric type for less than a grand.
Of course buying the electric one wouldn't be this much fun.

Stay tuned.

hah, and my crew complains about 21 lb crab pots in a 120 feet of water with an eight foot swell. Wimps.  Come on over here and crew for me Paul. I've got my eyes on some shrimp pots that I want to fish in about 600' of water....
 
I have a lovely manual davit. Will bring beer and the world's largest carnitas burrito.

I didn't say I had any desire to hand pull again  Angry  The worst part is both sets resulted in a dozen shrimp for each pull  Shocked  It wouldn't be so bad if the pots were over flowing with shrimp.  Actually on the second set we'd holed up during a gale and I half hoped the storm had blown the pots away so I didn't have to hand pull them  Tongue

And to think I was planning to get more pots so I could drop a limit of 5 pots.

If I keep the boat I'm not sure what the foremost upgrades will be, a Furuno fish finder is looking like #1, and a wallas heater #2, I guess that puts the pot puller #3.

Have you tried the Mr. Buddy propane heater.  I know that they are supposed to get more moisture in the air but people I have talked to who use them swear by them.  They are relatively cheap, easy to move around where you need the heat, have the ability to mount to a bulkhead, and have an oxygen sensor to auto shut off, (although you don't want to count on it).  I have limited space to have a built in heater.  The main cabin is pretty much off limits as I don't want to give up seating area so it would mean installing in the cuddy.  I know that others have done so, including Renn.  I don't do much extended fall camping so I am usually trying to take the chill off while fishing.  I use one of those Coleman propace catalytic heaters, (the one with the round heating surface) and it works pretty well.  I usually have a couple of windows cracked so moisture hasn't been a problem.  It will last all day with a 1 lb bottle.  Just a thought.

Moisture is one of the things I want to get rid of.  We have a serious condensation issue when we sleep on the boat, add to that kids that just have to get sopping wet and we need something that get's rid or the moisture.  I have the perfect spot to locate a heater, and with the combo of being able to cook on it, it seems like the way to go, just expensive.

Reduction gear rigs = huge money. This idea has been officialy canned.
Back to the pulley / axle idea.
I picked up a 2 inch pulley with a 3/4 keyed bore for the motor side. this cuts the rpm's to 1/2.
I think I'll probably need to reduce this again to get a reasonable speed on the windlass.
Ordered a capstan and folbe block, want to see how these work out.
I'm told that some people use the capstan alone directly driven from the crank shaft. That will be a last resort.

Don't forget to have a knife sheathed to leg at calf.  Just in case the line between buoy and lobster/crab trap becomes in contact and wound up with you appendage.  Just another safety feature for off shore trappin.
Good luck with trap puller apparatus.

Over the years I've seen multiple reports of recreational boaters getting their props caught in crabpot lines from silted in old heavy commercial pots, and getting their stern pulled down just as a wave overtakes them. It's not a pretty picture.  I keep a knife strapped to my davit, and have other knives strategically placed all over the boat for such situations. I also have my leatherman strapped on at all times and recommend my crew carry a knife.

Just the other week a couple fellows were out on the ocean and they got caught by a big wave and the boat turned turtle. They were inside their zipped up canvas pilot house and were later found drowned. I wonder if they'd of had a chance if they had knives on person.

Gonna order some more orange handled knives.

Capstan and block arrived today (Massachusetts).
I ordered them from go 2 marine in Washington two days ago  (cheapest rate).
That's pretty quick if you ask me.
