Hey everyone. Been a long time. Haven't had a boat in a few years, but picked up a used Ebbtide last weekend. Been too long.

I am questioning whether this trailer is long enough. The bunks extend well past the end of the trailer. I've seen many trailers like this,
but I'm not sure I like the idea.

Now, that said...I towed it 6 hours back home and it did fine. The GVW of the trailer is no issue...6,000lbs, dry weight of boat is 4150, so
no issues there.

The bunks extend a bit past the bottom of the boat, but I still don't like them hanging back that far.

Is this standard practice?

Looking at your pictures it does seem that the bunks don't extend as far forward as I am used to seeing. On my trailer they go forward of the wheels almost 2 feet.

I actually took a pic of this trailer BECAUSE it was so short, and at the time (2003) I never recalled seeing one with such a stubby back end!

Nice boat btw smile

while those appear to be 2x8's or 2x10's on edge, their overhang is holding up a crapload of weight beyond the end of the trailer. Is there any lateral bracing to keep the boards from splaying out over time? How's your tongue weight?

I don't care for the keel support rollers either, they might function okay, but they don't fit your boat...

JMO but I think that trailer likely held up a 19' boat in a previous life...

No lateral bracing. Don't know the tongue weight, but it doesn't squat my truck much and it doesn't sway.

I pulled it over 6 hours back home on Sunday. Did fine.

But I still don't like those long bunks sticking out there. I measured, they stick out about 32".

There's about 2" out past the boat.

Seems like a lot to me.

I don't have any good pictures of my trailer, to me it appears the bunks overhang the trailer too much and the bunks are not long enough to support the bow of the boat. I like how the bunks do extend past the transom a couple of inches. Also having a trailer that has too much capacity is just as bad as not having enough capacity.

Maybe a call to the trailer manufacturer would be worthwhile.

It's kind of hard to see where the engine is, but it might not be far enough forward that would put it on the supported portion of the bunks. I would suggest you have the trailer/boat weighed, including tongue weight to be sure things are in balance. There are some standards that manufacturers use to determine support and "balance."

The only experiences I have had with bunk trailers is with the bunk boards in a more horizontal position that mate with the hull like on the green trailer above . So, I can't really say anything about this arrangement. But, I can say that it probably could be better.

The 'bunk arrangement" seems to be how boat yards and lifts hold boats up, probably fine, to be honest. And definitely strong, most bunk setups, look at the green trailer above, they only hold the boat up directly above the bunk SUPPORT. Once the bunk board itself is more than 6" from the edges of the support pad, it's doing very little to hold up the boat. You could cut the middles out of the bunk boards and not affect the trailer's holding power. The main purpose of the whole board is a smooth transition between the supports. With those boards standing, the whole board is supporting the hull, and I would presume the board would eventually take the shape of the hull- or, maybe the other way 'round? I'm guessing wood will take a new shape before 'glass...

NADA sez your boat weighs around 3800#, pretty much any 2-axle should carry around 5000#....

If it were me, and I'm not real picky about adhering to accepted practice if 'it works': IF the tongue weight is, or can be made to be, at least 400 pounds, AND a lateral brace- or 3 of them if possible at the back, middle and front of the bunks to insure they don't start walking- can be added, I would consider it safe and would be okay with it.. smile

I don't have any specific figures to back up what I've heard/learned about the weight of the boat vs the capacity of the trailer, but I have heard that when fitting a trailer to a boat you want to be careful about two things:

1. if the boat is too heavy (or approaches the capacity of a trailer) the suspension of the trailer won't be able to adequately carry the trailer and protect it from sudden jarring like potholes.
2. If the boat is not heavy enough the suspension won't be flexed enough and will pass small road shocks through to the boat. This jarring could eventually cause screws/boats to loosen and could cause spider cracks on the gelcoat.

I remember when we bought our 36' fifth wheel right after buying the Skipperliner, since we made ourselves homeless TO buy it wink -- in checking the specs, the unit had a GVWR just over 15k pounds. So I check the tires, 4 of 'em, and they have a max weight rating of 3600 pounds... umm, times 4 comes to 14,400 pounds--? What the hell?? The owners manual was ready for that, and explained that the hitch weight, 2200 pounds IIRC, when deducted from the 15k GVWR meant only 12,800 pounds were on the tires. I still thought that was pushing it, but the trailer towed wonderful and the tires didn't LOOK overloaded at all...

That all said, I found a PDF on Master Craft trailer's website, and as to tandem axle trailers, their minimum max capacity is 7014 pounds total with a max boat weight if 4717 pounds. Their 'middle of the road' ratings are roughly 7500 max cap with a 6500 pound boat.

Just based on that, I would think the boat/trailer combo in question is okay weight-wise at least...
