[Fr. Frank]

Under my 23 Tsunami I had a galvanized Performance 2224T tandem axle with a 6800 lb capacity, 185/75-13" tires, and galvanized surge brakes, and in retrospect I think it was minimal for regular trailering for any distance. I hauled it 1000 miles round trip twice a year to the Florida Keys. I paid only $1700 for the trailer at a local marine surplus yard.

After I had it a only a short while, I found myself wishing I had spent the extra $180 for the 8000 lb version of the same frame with the heavier springs and the 205/75-15" tires, mostly because the 13" wheels and tires were really inadequate and wore quickly.

Moral of the story? Figure what you'll need with your boat at max loading weight, and add 25% to that figure as safety margin.

Under my 20' Seafari I have a 19-21' Magic Trail tandem with 4500 lb capacity, based upon the calculations below.

1800 lb hull + 300 lbs fuel + 400 lbs gear + 250 lbs in live well = 2750 lbs x 1.25 = 3437.5 lbs + 900 lbs trailer weight = 4337.5 lbs max gross vehicle weight = 4500 lb capacity trailer to purchase
