2020 Karavan Single Aluminium Jet Ski Trailer with Adjustable Bunks

Jet skis get used hard on Australian ramps and estuaries, and this is a trailer built around one of them. The 2020 Karavan WCA-1250 is a welded tubular aluminium single-place jet-ski trailer weighing only about 113 kg empty, with adjustable bunks so it can be set to fit different hulls rather than one specific model.

Why aluminium matters on a boat ramp

A trailer that goes into salt water twice a weekend has a hard life. Welded tubular aluminium does not rust the way a painted steel frame does, and the Sure-Lube bearing system lets you grease the hubs without pulling them apart – which on a ramp trailer is the maintenance job that actually gets skipped.

Setting the bunks

Adjustable bunks are only useful if they are actually set for the hull. Take the time to position them under the strakes rather than the flat of the hull, wind the winch strap up snug and fit a separate transom tie-down. A ski that shifts 20 mm on the highway will chafe a hole through the gelcoat over a season.

Registration

The figures above are the US manufacturer’s, converted. They are not an Australian ATM rating and this listing makes no roadworthiness or ADR claim. An imported trailer must be presented to your state or territory road authority before it can be registered. The rest of the range sits under container chassis and trailers; if you also need secure storage for the ski over winter, our container price guide covers the cheaper end of that.
