Nice shot of the boss on our XL with a big king - won the Evinrude corporate photo of the week contest eariler this summer. Dipping from this boat is ridiculous - tons of space, very stable, etc.

Alaskan XL SJ

Alaskan XL SJ

Well I finally made it to Seattle to the factory and met with Glen and Rob at Wooldridge. Glen sat with me for a hour and went over the specs and details on the new SJ. Than he took me out and showed it to me. Than we went for a demo ride on Lake Washington. The first thing I noticed when it was started is how "QUIET" it is!!! Than we took off and it is everything they have been saying about it for ride and performance. HANDS DOWN THE BEST SJ I'VE BEEN IN !!:topjob:! If you have not a chance to see one you have too.
I am a Wooldrigde boat owner and I hope to upgrade to a SJ for fall fishing. We have a few details to work out on my boat that I own now and when it is I will be ordering one ASAP..When I order it there will be some custom things designed and put into boat I asked for and I was told "no problem".. Nice to talk to a manufacter that will build it the way the customer wants it..

that's good to hear...the Wooldridge SJ is the 'real deal' for sure....I'm excited for others to check the boat out to see that not one bit of my review was exaggerated...:D...you really do need to take a spin in one to experience the difference....

be sure to post some pics when they start your build....

well I'm off to Chitna with the boat to try and scoop up a few...I hear the river is high and the dipping is slow...wish me luck, I'm going to need it...:)

Just wanted to say thanks for showing me the boat down in Chitna, and sharing all the info with me. Wish the dipping could have been a little better for you. About 8:00pm the water dropped enough the fish started running. Got 43 by 11:30, then had to run in the (darn near) dark back to the launch. NOT fun.
Very impressive boat you got there, and one of these days when I get rid of mine there's no question it will be another wooldridge.
Hope to see you at the boat shop on Sun. or Mon.

From the guy with the "Old Wooly" as you so kindly put it :)

tjm; thanks so much for letting us look at your boat. I stopped by the boat shop in ANC when I hit town. I was very impressed. The 10 indentations along your rail are where John had to pry my fingers off it when it was time to leave. Very nice to have the Phantom side by side for comparison.

I saw in the paper it was going to be on display again when the wife flew in. I was telling her how the Phantom was my old fantasy and the SJ Woolsdridge was my new fantasy and she was going to be able to see them side by side. Ops! you must have been out playing with your boat. Todd did a good job of helping explain to her about the differences between the two boats.

the sleeve with the SS liner had a diameter that was a touch larger than the stock sleeve....we tested the high skew with the stock sleeve....



in short, no....but our highly tuned :) method of timing how long it took to step the load did favor the high skew by one second.....we simply counted 'one thousand one, one thousand two'...and so on until the jet wash was coming out flat....so take that for what it's worth, not much....:).....there was no 'seat of the pants' difference to note...



I agree...I have the stock one installed right now and the rebuilt impeller/SS liner on the shelf for when the stock one gets a little worn out....if the high skew was cheaper I'd put one in just for the fact that sticks do not get caught in it as easily as the stock one.....which reminds me, I need to return the high skew to the folks I borrowed it from :shot:......

I dont notice much diff in normal running between the standard and the hi-skew... but if you load you boat heavy enough until it wont get on step with the standard, pull it out on the trailer, shove in the hi-skew, add at least another hundred pounds for effect to prove it to yourself, back 'er back in the water, hit the hammer... then I think you might see the difference. (and might not be quite so quick returning that impellor I think!)

Its sure good to see you back on the water this season again Toshiro! They couldnt have picked a better guy for this project developement.

it was my pleasure...if you need a bit more convincing I'm sure we could find a time to meet and take a ride....if you ride in the Phantom, then the Wooldridge, I am positive which one you'd choose....but don't get me wrong, you'd be grinning with either boat...

...and if I can help out with your quest to convince your wife let me know...:lol:

you weren't the first to mention to me about hearing the radio ads from Marita and then heading down there to take a look but not finding it....the ads ran the week after the boat was there...lol...

sounds like the way to do it...now why didn't we think of that...:shot:...that would have been nice to see those results....

Its sure good to see you back on the water this season again Toshiro! They couldnt have picked a better guy for this project developement.

thanks...I've been needing to pick your brain about a couple of pump questions....PM me when you're back in town...as awesome as this boat is, I can't help but think a couple years down the road....kinda' brainstorming about another gem Wooldridge can build....

Where are the videos from the load testing?

good question...

Here's what I know....the footage was sent to me on a portable hard drive several weeks ago...the footage was compressed far too much to be useable, it would have worked if you viewed it sized at about 2" square....the plan then was to send me the actual tape of the footage and I could get what I needed off of it to make a quick vid....

as of today, no tape in the mail...perhaps your post will serve as a reminder for the folks down at the shop...I'm sure they've been pretty busy...

I'll keep you posted....:)

Someone in my office gave me a Wooldridge flyer today that contained most of the same information as your post tjm (#326), so I decided to revisit this thread after a lengthy discussion with a co-worker on boat comparisons - is the offer still available to go on a ride if and whenever possible? I'm seriously interested in your set-up (especially in a wider boat) and may upgrade next year. I've read most of this thread (commenting a few times) and have only a few questions left I'd like to get your opinion on; hope they weren't already discussed..

1) Weight/Getting Stuck.

If I recall and understand correct, your boat's current weight is 2020 lbs empty which is much heavier than a 20' Alaskan XL (1350), a Phantom/SJX (1600) and a Predator (1400); how do you explain your's is easier to get unstuck? Granted a 20' Alaskan XL has a 76" bottom and a 98 1/2" beam which gives more displacement of water than the above named boats that average a 72" bottom and 91-94" beam. Still.. I would assume the extra weight would still give you issues once stuck. Speaking of weight, where the heck is the extra weight coming from with your 20' Alaskan? I know you upgraded the bottom of the boat, but, to me anyway, it seems that the boat's still a couple hundred pounds heavy. Where's the extra weight at?

2) Skinny Water.

No doubt you can run in skinny water without a tunnel (especially with your expeierence in a SJ) - but what happens after you stop and bank the boat? How much water do you need to get on step again since you don't have a tunnel? How long is your hole shot or does it take for you to get on step? What about when you have a load on board? To me there is a difference between running over shallow water areas and hunting in the shallows where you frequently land the boat and have limited spots to get back on step (if any at all). Have you done any tests in this regard? Personally, I'm still not certain which is better.. a tunnel where you can't turn as sharp and may cavitate, or no-tunnel where you can turn shaper but cant go as shallow as you otherwise could.

3) Weeds/Grass.

Any idea how your boat will run in the weeds or grass lands? I know that Phantom has a new Invasive weed system and am curious how Wooldridge's set-up does in comparison. For some this may not matter but for myself, well, it's a factor to consider.

I would venture to guess that the 1350# Alaskan XL figure is without an outboard motor hanging off the back...

I would assume the extra weight would still give you issues once stuck.

I have been amazed at how easily my XL with 175 E-Tec is able to get unstuck when compared to my previous 17.5' AK - it really does float like a dry cork; I attribute this to the much wider hull. Last moose season was heading down river just after dark and got hung up on a bar - was using a fuel drum someone had placed out on a sandbar as reference on which side to take - and I chose the wrong side - BETWEEN the drum and the near bank - $$#$@%#$#$@! Boat was sittlng in a very shallow trickle with hardly any water flow; the minute I hopped out the boat bobbed up a bit and you could rock it side to side just a touch. Less than 5 minutes of rocking L/R and 2 big pushes from the transom and BAM back in the channel. I was completely floored - the old AK would have taken a significant amount of time. Needless to say we idled the last 2 miles back down to the cabin :)

Speaking of weight, where the heck is the extra weight coming from with your 20' Alaskan? I know you upgraded the bottom of the boat, but, to me anyway, it seems that the boat's still a couple hundred pounds heavy. Where's the extra weight at?

I disagree with your assessment of what the tunnel does and doesn't do in terms of impact to performance - I believe a tunnel makes for sharper turning and holding the line as it acts as a "water keel" to keep the rear end from breaking loose - if your impeller is properly tuned/sharpened/shimmed it'll dang near throw you out of the boat on a hard corner. Keep in mind, however, my experience is with OB not IB, so not sure if your statement would hold with an IB configuration. The benefit of shallower running and bumping over debris is a definite plus for the tunnel set up.

3) Weeds/Grass.

Any idea how your boat will run in the weeds or grass lands? I know that Phantom has a new Invasive weed system and am curious how Wooldridge's set-up does in comparison. For some this may not matter but for myself, well, it's a factor to consider.

Is this new system you mention a function/feature of the hull or the pump intake? Sounds interesting, haven't seen/heard of it before.

AlaskanOutdoorsman, I can respond to a couple of your questions. The weight of 1350 lbs for the Wooldrige XL is for the outboard model boat without the motor or battery. The 2020 lbs weight is for the 20 ft Wooldridge AK XL with the sportjet package is including the motor and jet, battery and motor cover as it would be rigged at the base price. I took my truck with the trailer accross the scale then put the boat on the trailer and got the weight of the dry boat. As far as shallow draft the XL floats very shallow do to the wide bottom and the weight placement that allows the boat to sit very level and not be tail heavy. On the weed system I don't know what Phantom is doing but Merc has a weed grate avaible, the problem is that the one I have seen won't stop rocks. Glen

To second what Glen mentions to in his response, its also been my experience that tunnels sit lower in the water when at rest as comapred to a full/standard bottom. When you cut the tunnel/tunnels out of the bottom, unless its very light, the hull will sink at least until the contact surface of the tunnels is submerged and helpiing to displace the water/float the boat. Where I think a tunnel comes into play is when on step, then you have some additional inches of clearance to your jet intake where you might not suck gravel/sand quite as readilly as in a conventional full width bottom. I'd venture to guess that with two similarly loaded and set up boats, one with a tunnel, one without, you'll start out more readily and step more quickly in the one without a tunnel most times. I've found that with a tunnel/tunnels you also have to run slightly faster when on step if you wish to ride as high in the water as with a conventional bottom...

Also, its not a rule or law that a tunnel has to cause cavitation (for what thats worth) or lack of response in steering. My tunnel boats actually cut the corners harder and flatter than my conventional bottomed ones.

I dont think I'm explaining it very well, but to try sum it up, the boat/hull will rest and run higher in the water on a conventional hull than it will with tunnel/tunnels cut in it given the same speeds, loads, and designs, its really onlly the jet intake that runs higher in the water on a tunnel, thus giving lead to the many statements that a tunnel will run shallower (since most of us truly gage "shallow" by how low we can go without fouling our jets) when in fact, the conventional bottom since it rides higher in the water, will actually allow the "boat" to run shallower (although not necessarily the jet intake). When I get stuck its usually not just the "tunnel" area directly under the boat thats stuck, I'm usually high and dry across the full width and length!

Chriso, Some of my thoughts on tunnels. You have tunnels in inboards jet boats and outboard jet boats. On inboards if it's a Merc sportjet or a Hamilton jet they are both bolt in tunnels that raise the water to the impeller. There are all differen't size and shapes of tunnels in differen't size and shapes of boats. You put the wrong shape tunnel in a boat that aerates the water you will have cavitation. If you put a tunnel in a flat bottom boat it will cavitate in sloppy water because there is no vee to push the air out to the sides and the air goes into the tunnel and is delivered to the jet. As far as draft goes the only difference with a tunnel is the dissplacement of the tunnel, On our 17 AK model the sq. inches of the tunnel is 432. On that boat the foot print on the water is about 5 ft by 10 ft. When you take that foot print and take 432 sq. inches away it is equal to 1/16 inch of draft and would be less on a larger boat, now there are some tunnels that are a lot bigger and they would make more differance. Steering is improved with the correct shaped tunnel that delivers clean air free water to the jet and it also acts as a skag in the corners and funnels water into the jet. On a outboard jet a tunnel is huge as a outbord jet without a tunnel hangs down about 3 inches. Glen
