Title: My boat overhangs the bunks
Post by: Rhojo on June 15, 2010, 10:54:51 AM
My 22-2 is on a '04 Magic Tilt trailer with bunks. I've noticed that the boat overhangs the back of the bunks by a good foot and a half to almost two feet. I'll be replacing the bunks probably after this year because they are starting to show some age. I noticed this when I recovered them a couple of weeks ago. While the trailer tows well, no wandering or anything unusual, I'm wondering if the bunks shouldn't go all the way to the bottom edge of the transom? I haven't verified my tounge weight at this point, I've been told it shouldn't be much more than 200-300 lbs. which is about where I am now I believe. There is room to slide the winch up some but not enough to get to the end of the bunks and I think the tounge weight would be excessive at that point.

Please, help get me straight on this. I've heard so many different opinions on the position of the boat on the bunks and trailer I really need it from some that know for sure!  :scratch:

You may want to check out this thread on THT...

Lot's of opinions, including mine, for what it's worth.  Started by a 215 Explorer owner, whom I happened to talk into buying the boat! :cheers:

I'm with the last post on THT. Good pics there too of 2 different Aquas on trailers. If you want it exact as he suggested, adjust the axles, not the tongue. But if you have approx., 250 lbs of tongue weight, I'd say you're good. Mark the bunks where they're an inch from the end of the hull, pull back the carpet, and take a Skilsaw to the overhang. Re-fasten the carpet.......now THAT'S custom.... :lol:

I have 450lbs tongue weight on the 230. I kinda thought this was excessive but the trailer people didn't.

So if the the total approx weight of the 230, ready to go, is 4500 lbs...

Would that mean the tongue weight should be 10% or thereabouts....

I'll give our trailer guy a call, and see what their recommended ratio is.

10% is what all believe in...

I would say the boat weighs probably close to 6k when topped off with fuel, water, cooler, me....

Rick i agree with you on the weight thats about what i figure for my boat also.

Rhojo, per discussion, you may be a little light on the tongue weight. Easy enough, weigh everything at your local truck scales, and back it down from that. The 10% rule SB mentioned is what my trailer dealer also stated today. If in doubt he says go a bit heavier on the tongue weight, rather than lighter.  Your triple 2 will weigh in less than the 230's, but at least now you have a point of reference.

I just made a post on how to get the tongue weight at home if it's under 600 lbs.

Thanks to all for the input. I have to read through all this a bit more before I make any decisions or change anything on the boat and trailer. I'm definately worried about hull damamge from the bunks but I may be overly worried. I have to trust in the PO that they somewhat knew what they were doing when they bought this '04 trailer for the triple 2 but something still isn't sitting quite right for me with the way it is now and I will definately have to replace the bunks sooner rather than later.

JJ, Thanks very much for your diagram on getting tounge weight at home. That will be a big help to be able to do that myself!

My trailer was built for a Proline 210. I only have a 19-6. My transom doesn't even come to the end of the bunks, maybe overkill but I like a decent margin of extra capacity just for piece of mind. If you can post some pics of how yours sits will greatly help everybody make better suggestions. In looking at your avatar pic IMHO your trailer looks short. Warthog5 on Classic Mako always posts that your bunks should not extend more than a couple of inches beyond your last crossmember. If you agree with him then my trailer is still not correct! What is the weight of your trailer? Also what is its capacity? If you can give us more info we can help even more.

This is the way mine sits as of now.

Lewis,
Nothing wrong with that setup, as long as your tongue weight is good.  That real issue with bunks extending past the transom comes into play with trim tabs.  Tabs can get bent if they are left down a little or if they are mounted such that when fully retracted, the trailing edge doesn't come up above the hull bottom...

Hell, I've yanked 18 footers out with triple axles...want to see some long bunks?

Here is my current setup. I'm not sure these pics show it well enough. I'll try to get some better ones this weekend.

Oh, NOW I get it.....the BOAT overhangs the TRAILER...DUH....

 :oops:

Reminds me of a joke. The blonde calls the fire station...."Can you help me, can you help me, my house is on fire!!!!!"

"Yes mam! Can you tell us how to get there?"


"Duh!!!!......Take the Big Red truck......."

I currently have rollers,
Seems the bunk vs roller thing is also regional, up here on the Chesapeake i think rollers are in the  majority but when i visit our Florida home (east coast) it seems over 90% you see are bunk.
For future reference should i ditch the rollers where are my stingers located on my 170?
I would assume there fairly close to the edge of the coffin lid.

You've got inboard stringers and outboard stringers.  The outbord ones are where the bunks need to go, and hopefully where your wobble rollers are located.

Open the pie forward of the motor and take a tape measure, extend if over to either side until the end hits the stringer.  Note the distance to the center of the pie.  The center of the stringer should be about 3" further outboard.  Do the same for the other side, sometimes stringers don't end up where they were supposed to go... :scratch:

thanks for the reply, open the pie?
If you mean the inspection cover that i have seen in some boats mine dosen't have one in the back only one over the fuel sender.

i thought this was posted in the bunk vs roller folder, oops

Ok - I've been waiting for this:
Just the opposite - My bunks overhang my boat  :!:  :!:
http://www.classicaquasport.com/gallery/showphoto.php/photo/2004/sort/1/cat/500/page/9
I inherited a boat and trailer from my mom and the boat was given away and I kept the trailer because of the nifty auto latch it has. Anyway, I put the 170 on it.  For me the ease of getting in the boat from the back while on the trailer surpasses the looks I think I get as I go down the road.  :wink:  Been like that for 22 years.

One thing that will add to this topic though is the support that this trailer gives the boat.  The trailer was for a much bigger boat and you can see that if we follow the "under stringers" rule - she fails.

Again, been like that for 22 years.
Been thinking about putting some inboard bunks on her - for 22 years  :lol:

Now Rick, you know as well as I, the oversized bunks aren't going to hurt your boat...they just look funny...(http://i259.photobucket.com/albums/hh301/seabob4/Smilies/roflsmileys.gif)

The positioning on the hull is not bad either.  Notice how they sit at the transition from the chine to the hull bottom.  Next to the keel, this is the thickest glass on the whole boat.  If they were way inboard, say between the outboard and inboard stringers, you would have a problem.  But they aren't.

Maybe in another 22 years you'll find that trailer made for your 170.  But in the meantime...(http://i259.photobucket.com/albums/hh301/seabob4/Smilies/cheersemoticon-1.gif)

My 225 overhung my trailer bunks for a while, but after 2 adjustments to my winch stand, the transom now sits 6" forward of the end of my bunks.

I know it was probably perfectly safe, but I always felt nervous seeing the tail of the boat hanging off the trailer!
