Hey brats, anyone have any ideas on what it would take to get a r21ec to achieve a cruise speed of 12-14 mph? i boat mostly in the hudson river and LIsound i want to buy a r21ec took a demo at dealer [coeymans] in upstate NY and luv that little tug.a brief history i have owned manny small deep v hulls and over powerd /proped for top speed only for poker runs and pleasure and i know it doesnt apply to this site so i wont bore u guys with that. i would buck up for more hp /would the hull handle it? and still track right ? my concern is i dont want to crawl against current in hell gate or east river i boat alot in LI NY and it can get nasty out there ! didn t mean to get so long winded been a member since sept 07 and this is my first post thanks in advance brats /luv this site and will start through in my two cents from now on . also cant seem to find hardly any info on r21ec /tests /reviews? anywhere not lookin to run mid 90s like my hustler 26 just lookin to hear from someone with expierence with this type of hull design . sea wolf? :? thanks again brats john
 
I have the 3QM30 Yanmar (30hp) in my tug and I can't do it.... really pushing hard I might make 12 but not much more..... I bet you need 50hp to be able to get 14mph. Possibly you could turbocharge the three cylinder and get it....but I don't know..... If you could get the hull up on plane I would think it would go ......but I have never been able to approach that...

12 to 14 knots would be an ineffecient speed for the Ranger 21. I agree that you would probably need considerably more hp--and then you may exceed the good handling speed of the hull. Some displacment and semi displacement hulls just don't do well at these speeds of 2 to 3 x length of the waterline.
 
thanks for the reply Joel .i was thinking of ordering 21ec w/o power and trying to fit a 50-70 hp,mabey move the bat. and squeeze in more hp will try to get specs from factory guys they seem approachable from what i hear on this site . full out at about 12 mph whats she like i mean is the bow out of the water a bit? do you think it would cruise all day like that /with more hp? mabey wobble port to starboard kind of like chine walkin adeep v? appriceate any info i have a small JD tractor with 3tne74 20hp yanmar that i run wide open all the time not that i would do that to the tug but trust me 1100+ hrs of abuse and sill runs great . know its been asked a bunch here but cant get enough info on how she handles rough water thanks again all john
 
John,

Have you considered a CD22 or CD Venture 23? Those boats will go either slow or fast enough (20-30 knots) to conquer Hells Gate.

You might try a PM (private message) or phone call to Les Lampman at E Q Marine. He is very knowledgeable about the Ranger Tugs and he likes the 21.
 
thanks for replys ill try eq cant hurt . nothing against cd 22 just got my heart set on 21ec /my next idea is to see if dealer at coyemans will let me hang a90hp honda off the transom or 2 smaller out boards tryn to figure best way with out damage transom. hope you guys dont think im nuts (well a little mabey) just would like to get 4-5 more mph at cruise once again thank you john
 
No.... Even if you could do it....it would be thrilling and expensive.... I think that once the tug got up on plane it would act pretty funny ....
Originally my Tug came with a two cylinder Yanmar.....and I replaced that with the three cylinder....more power... but it was not to go fast.... I work the tug and I needed pulling power.... it now has that..... it went just as fast with the two cylinder as the three..... it's that hull speed thing...
There are harbor boats that have a much faster cruise.... ya might as well give up and get one of those.... if you don't like slow.... these are not the boats for you...

Hey there,

Maybe I can save you the email. :)

I'm am NOT speaking for Ranger or the Livingstons here...just me, my self, and I. I hope I don't spook them too badly!

I do believe that you'd find the 21EC to behave pretty well if you could push the speed to the mid-teens. With a brand-new boat, just me, light fuel, and no wind I could tell the boat was actually planning pretty nicely at wide open throttle. My sense was with about 50-hp that she'd just make enough extra speed to get to a comfortable mid-teen cruise. A turbo'd Yanmar 30 if they made such a beast would have been perfect for that.

The thing that is unique to this hull is that it really isn't a displacement or semi-displacement hull the way it used to be (really just displacement back then). When the Livingstons redesigned the hull it got a nice wide planning surface aft (really like a lot of recognizable planning hulls). I can't tell you what the angle of the quarter buttock line is because I never saw the drawings or asked but the 21EC does not squat when you get near planning speeds so I suspect the angle is very close to zero or just a tad more.

I know SEA3PO and Bob Austin are thinking more traditional semi-displacement hull forms and I concur completely with their thoughts if that were the case.

I'm not sure Ranger would want the 21C to go any faster but I don't think it would be a problem if one weren't looking for very high speeds (over 20 say). The boat does have a keel so one thing to watch out for is the outward lean (like a car) that the boat will have at higher speeds. It has fairly soft chines and I suspect at too high a speed with an over zealous hand on the wheel you could really get your adrenaline running in a hard turn. Run with a modicum of common sense I think it would be rather fun. :)
 
I would think the Ranger 25 with the Cummins would have the same concern in an emergency turn at speed, with quite a bit more weight up high.

Totally different hull shape; the Ranger 25 acts as a typical planning hull and leans into the turn rather than out.
 
Hey Les, dont worry they probably dont spook that easy . thanks for your reply thats all im lookin for acoupple mph. the day i went for a demo of course it was flat like glass, and the gps never pushed passed 11 mph (3 on board) guess i will start by talking to fact and go from there. it was nice hearing from someone with experience on the boat do u know of any tests that have been done on 21ec cant seem to find any ink on it.sounds like ur a dealer for them woud u be able to mail me a brouchure on them -local dealer here said he had some but ran out ..........JLF Excavating po box 329 Cornwall NY -12518 thanks brats
 
Bill if i werent singel handedly running my excavation co. and u werent so far away i would love to do a R&D experimenting with u . would any one out there be interested in taking me out for a coupple hrs on thier tug in ny area my 10 min demo didn"t really cut it .FUEL-LUNCH -BEER on me come on guys u remember what it was like before u bought yours ........thanks....john
 
Rock Hall is easily accessible from NY down I 95 to 301 -- great crabs, cold beer and you can watch folks with big boats and no skill try and enter the harbor and try to tie up at the restaurant. The Ranger dealer is on the other side of the harbor

Powered a friend's "new to him" Sabre 32 sailboat out with a heck of a headwind and an inbound 45' power boat trying to hog the channel -- his wife was on the bow trying to give him directions -- funny as all get out except she wanted us to back up!

Its warm here in Fl. and we have 2 !Possibly some prop work [ smaller dia. more pitch] could squeeze a little more speed ...........I think they have tried a Volvo 40 and dont know the results.....

Hi again,

I was involved with the boats early on but we are not a dealer. You can grab the brouchure online from here. There's information at that site and the download links in the lower right corner.
 
thanks for replys all/ i sent a e-mail with questions to fact. on thier site keep u posted on results about more hp.i know there is a lot small boats simillar to the 21ec out there / kinda have my heart set on 21ce. that volvo 40 sounds insteresting ? i read about in a post somewhere here but no real preformance info un fourtunatly .another thread here is about the 25 with cummins&more hp so im thinking the 21 may not be too far off. I know most of my cruising would be at 5 to 7 kts and that would be fine with me but a few more knts and im sold .I would hate to buy one with no power and have to butcher a 50 or say a 75 in it but whatever it takes is the only way ill purchase .hey wefings can i get a demo ? i"ll be in florida (west palm) w/girlfriend to visit her mom as soon as i know it"s not going to snow any more (com. snowplow contracts - can"t go to far) guess early april . where are u guy located? always hear good things on this site about u guys thanks-gang hope to hear from u soon...john
 
well got a response from Jeff at factory he said "no room to fit anything larger than yan 30" also said it works "pretty well"????? guess id have to agree it doesnt work well.............dissapointed,,john
 
I thought someone near Seattle repowered with like 40hp last year and
not long after that the boat was for sale.
That is if I remember right. It may be in the Ranger archives somewhere.
Myself I don't use the 30hp most of the time but if I wanted to go fast I
surely would got a CD22. The slow speed of the Ranger is fine with me.
Good luck on your search for the perfect boat.

ps good to see you on here Les, getting the boat
ready for a trip in land of the Byrd..
 
k7mxe,Ikeep hearing about this myesterous volvo 40? couldent get any info from the factory about it .re read my previuos post about it and wish now i worded it differently ,did not mean for it to come out so negativly,kinda had my hopes up they would work with tryin to install a pinch more hp . i"m very interested in buying a 21 and like it alot , most times i would be happy with hull speed of 5-7 mph,but it sure would be nice to go a bit faster at times,they advertised new tug in brouchure saying"higher speeds" "bringing more cruise destinations whithin easy reach ",imean come on 2mph? 3mph?more speed? ,a one way cruise of 25 to 30 mi,5 to 6 hrs?please dont take me the wrong way /but u know how it is mabey a long 10 mile streach in bad weather/or tryin to stay to stay ahead of it a few mph would be nice.i really do appriceate all info-disscussions on this site i"ve always done a little reasearch on any major purchases; and cant even find any info on 21ec anywhere?can u ?thats mostly what i"m asking for. from what i"ve heard here i didn"t think installing a 50 horse would be impossible ,im by no means rich but ,i would be willing to pay for engine up-grade . my apoliges to jeff or anyone i may have offended. if the price is fair without power i'm gonna try it myself.ive read all the posts many times hope more 21 owners will chime in any info /ideas/handeling /abilites ?are greatly appriecated .........john
