Looking to put a new trailor under a 1995 18' Larson with 3lt Merc inboard. Any opinions on bunks or rollers for this boat? It currently sits on rollers so that is my first instintive choice, but I thought I would investigate the bunk option.
Thanks...

Re: Bunks or Rollers???

Everyone can argue the merits of bunks or rollers though my belief is that it all comes down to what are the ramps like where you will be using it most. If they are flat and shallow then rollers are the only way to go. If they are not then it really doesn't matter.

Re: Bunks or Rollers???

I personaly like bunks with keel rollers. I belive bunks give better hull support. I have a roller now, and its setup good, and havent had any issues, just have to remember not to unhook the strap until the boat is over water.

Re: Bunks or Rollers???

I think rollers can tend to lead to more "premature launches" than bunks because of the lesser friction quoefficent.

Re: Bunks or Rollers???

The one I have may be a smaller lighter boat but when it is sitting flat on the roller trailer it will not freely roll off w/o a push. Even when at the ramp I normally use which isn't that steep it still requires a push to get it rolling.

I would rather be worried about "premature Launches", which can be prevented than arriving at a ramp only to find I can't use it because I cant get deep enough to get it off the trailer!

Re: Bunks or Rollers???

I fought a bunk trailer for years and now love my roller trailer. The first time I used it I almost prematurely launched it but that's a mistake you only make once. I can load and unload anywhere with the rollers. People talk about leaving dents in the hull, mine has sat on that trailer for 30 years and there isn't a mark on it.

Wish I had pics or remembered the mfg, but I saw a trailer a lot last year for a bass boat. It had conventional bunks, but also had a set of rollers that would cantilever up, raised by a second winch up front. Best of both worlds! The boat would rest on the bunks, but if you needed to do a shallow launch/recovery you could turn it into a roller trailer.

Re: Bunks or Rollers???

There are a few factors to consider. Bunks are cheaper than rollers being the most basic, and the reason there are so many more bunks. The rollers for me are an advantage that I wouldn't trade. Every access no matter how bad it is becomes an easy access with the rollers. In MN we have a lot of really bad accesses. I think of it as a typewriter compared to a brand new quad core pc. At least at the many accesses I use, and the situations I encounter, Id rather have the better technology. I probably don't absolutley need it but life is a lot easier with it.

Re: Bunks or Rollers???

I converted my roller trailer to bunk because I hated the rollers for the launch I mostly use which is a unique situation. I have taken my 16 foot boats all over the midwest, mostly Minnesota, Wisconsin, Illinois, and Michigan, and have never had a situation where I couldn't launch using the bunk trailer.

One of my other boats is a 16 foot bowrider too and I switched the bunks to bunks with rollers mostly because the bunks needed replacing anyway. Regardless the difference in weight between my Sig boat which is heavy and the much lighter 16 footer with outboard makes the rollers less of a luxury a bit like pulling out a tinny with a diesel is overkill. I could also still use a typewriter for my business as well. I can't count the number of times over the years I've watched bunk trailers struggle (usually not with light/small boats nor beginning boaters) to do what a roller trailer does easily. Again, however lots of difficult accesses.

Re: Bunks or Rollers???

i see sooooo many post about poeple not being able to load there boat on a roller trailer, i dont think i will ever get another roller trailer! certain boats load better on certain trailers. i have bunks wihta 23 foot cuddy loads perfect every time mostly i load it by myself no issues! my dad has a 15 foot lund with bunks and that dam thing never loads right unless you drive it half way on back the trailer in further and crank it on the rest of the way. i dont like rollers for the fact that if i am by my self the boat tends to roll back and makes it just that much harder to launch and retrieve.

also if your by yourself with a bunk trailer tie a 20 foot rope to your boat and trailer and back in the water slam on the brakes it flies right off then pull forward enough to tie the boat off and park. [i seen a local sheriff do this]

it does matter some what, what type of ramps/waters you boat in. if your in rivers then bunks, if your in shallow in-land lakes then maybe rollers are best. you dont want to burry your truck just backing the boat in the water because it wont come off, makes it twice as hard to pull the boat out.

Re: Bunks or Rollers???

Generally, the hull will sit higher on a roller trailer.

You need to have the rollers sticking out of the water to properly load and center the boat.
Since you can't float the boat on up to the front, you will need to find a way to connect the winch strap with the boat 8-12' back. Usually means getting your feet wet if you are loading by yourself.

I have converted 3 trailers from roller to bunk. These trailers were wide enough for the hull to fit between the frame rails.
Removing the rollers allowed the hull to sit 4" lower on one trailer; 7-8" lower on the other 2 trailers.

Now, didn't have to back in as far.
Loading was easier as I was able to float the boat to within 12 - 24" of the bow stop.

I actually launched off the bunks in just 8" of water. Water wasn't even up to the axle on the trailer.
Had previously applied car wax to the bunk carpet. Pushed the 1300# rig off with ease.

I'l take bunks on a wide low frame any day, for launch or load.

Re: Bunks or Rollers???

around salt water, rollers are preferred so you can keep the trailer parts out of the water. Or used to be, until bunks took over the market b/c they are cheap and appear to be easy--the sellers don't see them when they rust out.

trailer. er.

Roscoe, you're a bigger, better man than I! If I tried that they would be calling the paramedics for me. How well did that boat go back on to the trailer in that shallow of water? Besides I don't think my semi-V Lund would fit onto a trailer like that.

Actually only 5'9" 200#, or I was back then.
Boat was a 1995 16'8" Spectrum aluminum with a 70 hp, 12 gal fuel, 3 batts, troller, fishing gear.
Typical escort trailer that they sell with Bayliners.

Bunks were set up to be 1.5 inches higher in the front.

I had backed out into the lake about 100' past the end of the concrete and was afraid to go any further for fear of getting stuck.

Was able to push her off with very little effort. Like on those commercials for the white plastic furniture movers, where the guy moves a car by pushing it sideways.


The combination of the car wax, and a coating of wd-40 made the boat glide.

I did have to go find the other deeper boat ramp to load her up though. Ended up walking almost 2 miles back to get the truck.

The current trailer was nice, but I was able to lower the original bunks another 3.5" by removing the bunk brackets and using a hat bracket from the under side of the cross members.


Why do I do this?

Wilderness trips to Canada where we beach launch and we can't back the truck into the water at all. And the less moving parts on a trailer that is gonna be run on abandoned logging roads -- the better.

Re: Bunks or Rollers???

Ok guys, I have to post this for the guys that think that it is hard to load a boat on a roller trailer.Roller trailers all the way!!! Bunk trailers are a PITA. I will never own one. Get yourself a self centering roller trailer, set up perfect for the boat your hauling and you will never turn back. Also a good trailer will have plenty of rollers so you don't get soft spots. I have never had any damage to any boat using a roller trailer. Here is what I posted on the "trailering solo" post.

Ok, Finally something I consider myself an expert in,lol I have been self launching my boats since I was a teenager. I am 41 now. This is how I do it.

1. Prepare boat before you get to the ramp with all the gear that you will need for your trip. Ice,coolers, fishing gear, cell phone, fenders, lines, etc. etc. etc. This will differ from person to person.
2. Install the drain plug and leave the keys in the ignition while still at home. Have a chock and line ready in your truck.
3. Have fenders staged at cleat locations if they will be needed. My ramp has a edge bumper so no need for fenders.
4. Approach staging area for ramp. Remove tie down straps from stern of boat. Tilt motor half way down.
5. Remove line from truck and tie it to your front cleat, coil the rest of line and place on bow where you can easily grab it once boat is backed down the ramp.
6. Once your turn comes around, back the trailer/boat into the water just so the stern is floating slightly.
7. Put truck emergency brake on, then put it in park. Exit vehicle with trusty wheel chock in hand. I use a rubber one.
8. Put wheel chock behind rear wheel on driver side.
9. Take rope that you tied to bow cleat and wrap one full turn around trailer winch post. rope should be tight from cleat to bow winch post. This will act as your launching come along.
10. Take safety chain off. While holding rope in left hand tightly, loosen winch cable until rope in left hand becomes tight with the weight of the boat. Now remove winch line from boat completely.
11. Once the winch cable is removed, use rope wrapped around winch post to slowly let boat slide off trailer into water until completely floating. This is done by keeping the rope wrapped around winch post but slowly letting the line out until the boat floats completely
12. Once the boat is floating completly off the trailer, use the rope to pull your boat around to the tie off spot.
13. Once boat is tied off, retrieve wheel chock and pull truck/trailer to parking spot.

Now, loading alone is quite easy also. This is what I do.

1. Stage boat at loading ramp and wait your turn.
2. Get truck/trailer while waiting.
3. When your turn is up, back trailer in so axles are about half way in the water.
4. Set emergency brake first and then take out of gear into park. In this order it will help you get the truck in gear when pulling out.
5. Once in park, exit vehicle with trusty wheel chock in hand. Put wheel choke under drivers side rear truck wheel.
6. Retrieve boat, drive boat slowly on trailer until bow is centered and basically stopped at the rear of trailer.
7. Tilt motor half way and power up until boat loads onto trailer all the way up to the bow roller.
8. Keep motor in gear, powered up enough to keep boat solid to the bow roller76 and to prevent it from slipping backwards off the trailer..
9. With motor in still in gear, walk to the front of boat, bend over bow and hook safety chain up. Then hook winch cable to bow ring. Crank winch cable until tight.
10. Once boat is firmly winched, walk back to helm. Do not shut off motor yet but idel down. Still work to be done here.
11. Look over both starboard and port and make sure stern of boat is centered on the trailer. If it isn't centered, use your motor to center the stern of the boat by turning the wheel right or left and throttling the motor enough tell the stern moves where you want it.
12.Once completely satisfied your boat is centered, shut motor off and tilt motor all the way up.
13.I usually at this point, walk to bow and step off on back of tailgate on truck to exit the boat.
14.Next, do not remove chock, chances are you wouldn't be able to anyway because of the weight that has been put on it..
15.Get in truck and after putting foot on brake heavily, put truck into low gear. Now remove emergency brake.
16.Slowly pull trailer up to top of ramp and stop. Put emergency brake on and into park. Retrieve your chock so no one runs over it.
17. Walk back to truck and pull boat to area away from ramp where you can install your safety stern straps and make sure the boat is ready for road travel. Antennaes etc.

Bye the way, this will work with almost any size trailerable boat. So you know, the boat I have now weighs in fully loaded at around 8000 pounds and I load and off load myself all the time. Only difference with different boats is the access to the bow. Fortunately, mine is a walkaround and all the other boats I had were center console.

Not to toot my own horn, but most people just look at me in awe when they see me loading or unloading, takes all of about 2 minutes. Ok, maybe 3 minutes. Take your time and don't let anyone rush you. Practice makes perfect, try it when the ramp is least busy, usually during the week. Hope this helps someone.

By the way, this will work with a bunk or roller trailer. I personally like and have a roller trailer, but to each his own. You have to find the sweet spot for whatever trailer your using. Every trailer/boat setup is different, but you should be able to find out how deep your trailer needs to be pretty quickly. I have a dual axle trailer, the back tires are almost completly covered when backed in and the front tires are about half way covered with water when in the right possition. I really prefer that no one helps me at the ramp, it is much easier to do myself.
This is the boat I trailer now, load and offload myself.

Re: Bunks or Rollers???

Check out my post above, you are wrong on many accounts.

Most roller trailers should have the rear rollers in the water when loading. The rest of the trailer should be out of the water.
You drive the boat onto a roller trailer, thats whats nice about them. If you changed over three trailers to bunks because you didn't know how to use the trailer, I feel bad for you. No offense!

The good thing about a roller trailer is you won't have to push or pull the boat of the trailer ever. Ohh and you will never have to add wd-40 or vaseline, or plastic strips, or all the other BS people try and add to make a bunk trailer work in all conditions.

I'm not bashing you so please don't take it that way, I just want to make sure that the Op has the correct information about roller trailers. You simply were not loading your boat correctly. By the way, as I stated above in my earlier post, that way of loading will also work on your bunk trailer as long as it is somewhat self centering.

Re: Bunks or Rollers???

Ok, so I am going to point out more bad info. Show me the posts of people that don't like there roller trailer? I have seen alot more bunk owners that have complained about not being able to get the boat off or on. The method that you suggest in slamming on the brakes to get it to come off is a dangerous method and one you will never have to do with a roller trailer. If you load the way I posted earlier, the boat will not roll back, it can't. Also you will never have to bury your truck to load or unload from a roller trailer if you are using the trailer properly. The only thing in the water will be the back set of rollers, the rest of the trailer is out of the water.

What is the difference of inland lakes and a river? Other than current, not much at all. I am on one of the biggest rivers (ohio) and have a roller trailer. The point is a roller trailer will work on any ramp with any amount of water. I have off loaded and loaded on very steep to very flat ramps in salt water, rivers, and lakes. There is no ramp that a roller trailer will not work at!

Also makes it much easier to maintain the bottom of the boat. You can simply roll the boat back to unload on stands or for bottom painting, trailer maintenance etc.

I also have to say, just because you had seen a local sheriff do something, doesn't make it right! Ok,sorry, I'm done with my rant.
i see sooooo many post about poeple not being able to load there boat on a roller trailer, i dont think i will ever get another roller trailer! certain boats load better on certain trailers. i have bunks wihta 23 foot cuddy loads perfect every time mostly i load it by myself no issues! my dad has a 15 foot lund with bunks and that dam thing never loads right unless you drive it half way on back the trailer in further and crank it on the rest of the way.

Re: Bunks or Rollers???

Wow Chris...I guess you really like roller trailers....LOL. I couln't agree with you more.

The posts that you commented on raised the hair on my neck as well. The only reason I didn't reply myself was because its a losing proposition. People have a certain mindset and nothing will change their mind. The problem is that 80% of the trailer boaters, no matter what kind they use, don't even have half a clue how to launch a boat. When I go to the ramp I'm usually met with 3 or 4 others at the same time. My facility can launch 6 boats at a time. If there are 4 others there, its certain that 3 are clueless. Not just the new boaters, but the old farts as well.

When I got my first boat in the 1960's I read a book how to do it. Then I spent countless hours sitting at the ramp watching other before i tried it myself.

In 45 years I only had a problem ONCE. That was the first time i used a bunk trailer. It never went back to the ramp again. The bunks were ripped off the next day. Actually, it wasn't a real; "problem". Its just that I couldn't do it by myself so easy, I had to get my feet wet, and I had to back the car in too far.

I wonder if there is still a "book" in print?

Actually only 5'9" 200#, or I was back then.

I had backed out into the lake about 100' past the end of the concrete and was afraid to go any further for fear of getting stuck.

I did have to go find the other deeper boat ramp to load her up though. Ended up walking almost 2 miles back to get the truck.

Why do I do this?

Wilderness trips to Canada where we beach launch and we can't back the truck into the water at all. And the less moving parts on a trailer that is gonna be run on abandoned logging roads -- the better.

Like I said, You're a bigger man than I! And at 57 years old and having been through 4 leg surgeries on both legs I don't think I would want to be walking 2 mi. back to get my trailer. Also what you decsribe with your fishing trips is extraordinary. Few people will ever face those conditions. So that puts you into a kinda unique position.

On the other hand the roller troaler that I have has 5:30x12 wheels on it with a straight axle. All I ever need to do is be deep enough so that the axle touches the water and I can launch and retrieve w/o any trouble and do it solo w/o getting wet as I have added a catwalk.

I will add that the whole purpose of this boat and trailer was to be able to use it in very shallow conditions at unimproved ramps and be able to do it alone. Now if I was to go to a bigger boat for bigger/deeper water with improved ramps I might opt for a different set-up.
