Single axle or dbl

[bullfrogin83]

Getting ready to pick up a 2019 starcraft EX20C. Was wondering on what trailer to buy as far as single or double axle. The guy at my local dealer said a single would be fine. Thoughts.

Need to look at weight of boat and make sure trailer is rated for it. A single axle is sometimes easier to maneuver than a tandem axle.

Well I did a quick Google search and found it's dry weight of 1850 lbs.

Another quick Google search found the max for a single boat trailer axle is 3,500 lbs.

So let's say an outboard weighs around 200lbs. So now your looking at 2,050lbs. That leaves 1,450lbs for gas and gear.

Google is your friend, easy to do your own research.

If you have to move the loaded trailer by Hand, then the Single is the way to go. On the other hand twin axles allow for the use of smaller tires, allowing the Trailer, and the boat to be lower, making it easier to launch/load. But 2 axles means twice as much maintenance, and twice as many tires to eventually replace, granted each small tire is likely cheaper. 2 axles also offer the the possibility for double the Brake Capacity
On a Tandem, especially one with Torsion Axles, the Hitch Height is Extremely Important, as the Trailer needs to be almost perfectly level to ensure that both axles are carrying the load evenly between them.
Your boat and motor sound fairly Light, and most Tandems start at 4000 lbs. EZLoader has a Single that is speced at 3700lb load

Load Rite & Venture sell single axles with a 5200 lb capacity axle and they have load capacities of approx 3600 lbs, plus the weight of the trailer. If you have a tight storage situation & need to maneuver it by hand the single is the way to go. They are also easier on tires because the tires don’t twist on the rims when you make sharp turns. I replaced my 3500 lb axle with a 6,000 lb axle, leaf springs with 5 leaves, 12” surge brakes & 15” tires with 225/75-15 load range D tires. The trailer frame is the same gauge steel as the higher capacity trailers so it worked out fine. So if you go single go for a HD trailer….

Ditto @jimmbo 's points. You will be fine with a single axle trailer.
I like to keep things as simple as possible. Our new boat + trailer weigh 3740# wet with 15 gal of fuel and a little gear. Trailer 15" D range tire capacity is 4300#. The 560# reserve is more than enough for the life jackets and anchor. Before I put the boat on the trailer I always burn the fuel down to five gallons or so. ...also 8-10% tongue weight takes a few hundred pounds off the trailer tires.

The 225/75-15 Load Range D tires I have on mine are rated at 2540 lbs each for a total of 5080 lbs, as far as tires. My axle/hubs/brakes are good for 6,000 and the springs (5 leaf) are good for 5700.
Trailer has 4650 on the axle and 420 lbs on the tongue, total 5070 lbs.
First time since I've owned it that it hasn't been overloaded lol. But my trailering consists of driving to the boat ramp (1 mile) and boat yard (1/2 mile) each year for bottom paint. Fixed it just because I might have to trailer it further (paint/fiberglass repairs, on the South Shore of Long Island, like 15 miles from here.
Hemi powered Jeep pulls it easily, rated for 7200 lbs.
