a good mate and his brother bought 2 of these dinghys new sametime (pretty certain they were Bluefin, made in Qland)
Less than 18 months later BOTH have been replaced due to constant and serious cracking.

Company offered $50  towards repairs-a welder in the NW wouldnt even wipe his ass with $50 let alone patch them up even nowadays

Bluefins are made in Qld. I have the 4.2m Rogue which is much heavier build than the Rascal. I have a 30HP Honda on the back and have given it a fair pounding including dragging it over rough sand tracks and beach launching onto sand at low tide. I have had no issues with cracking and am very happy with it.

My only complaint is that the angle of the transom means that even with the outboard trimmed in as far as possible, with only one person on board and being tiller steer, it is hard to get enough weight up forward to keep the bow down. I have to carry an extra 20L fuel tank and put that and my tackle box and anything else on board up near the bow. Mind you, I did fit dual batteries and both of these are right at the stern, so it is carrying affair bit of weight aft.

Interesting comments on the Blue Fin. We are currently looking at Tinnies & checked them out on Saturday.
Mainly the 3.9m.
Jupri, I would put big dia wheels/tyres on & carry a spare especially if you are launching off the beach. Bigger diameter is better than small on sand. I am building a box trailer to carry a tinnie as well & am putting 15" Hilux wheels on it.
Good luck with your decision.

Blue fin has gone into administration. Shouldn't affect you getting a second hand one, but if you got a new one it might affect your warrantee.

Interesting to hear that DTrain, thanks for the heads up.

not sure on the typical state of the beach your launching off but a drop down wheel setup might be a good idea you you can un-hitch and push the trailer in the water if you wish
martins trailer parts sell them
15 inch wheels mean you need to back your trailer in further so beach launching everyday is not good news for your Suzuki ;)

As Rig says, bigger wheels equals need for deeper water to launch, so if getting the trailer custom built, be sure to get it made as a break-back. It also helps heaps if you are retrieving the boat on the beach in low water. You can take the trailer off the hitch, wheel it out, break its back, winch the boat on and then manhandle boat and trailer back to the car (which is much easier with the drop down wheel as mentioned above, but still manageable with a small dinghy and two blokes). You can do the same without a break-back trailer, but it is easier with the break-back facility.

Maybe if you are having it made, concider bigger wheels but have a drop axel fitted.
Keeps it low but still bigger wheels, best of both worlds....

 Thanks for all the advice everyone.

Good to hear Makai is a happy blue fin owner.  I am familar with the buluefin brand and have great confidence in them. I set my dads boat up, the 3.8m Varmint a couple of years ago. After visiting dozens of boat yards blue fin stood out especially in the build quality. We had some work done by a great ally welder adding dive step,ladder, fuel tank rack and chine to chine flat floor. Even he was impressed and said that they were the best constructed tinnies he has come across. In particular the quality of welds, no rivets and attention to detail in the finish. Since then that tinnie has been all over WA an fished many remote locations from point nyuts, up to beagle bay. I will check with the guys at dinghy world and call blue fin tomorrow to see if they are indeed going into administration as I would like to know that for sure. 

Anyway picked up the motor today. The yammy looks like a good choice. Picking up the hull after lunch tomorrow then heading to meet with the guys at papas for measuring up the trailer. Have organised hubs to suit the zuk wheels and martains will make the axel to order so the trailer matches the wheel base width of the zuke and runs in the same tracks. So the zuke is 1600mm wide and the tinnie is 1660mm. Which means the tinnie will sit just above the guards not between them. So it will be high but the offroad capability is important for travelling, this rig will be going all over oz pretty soon.  My local beach launch (falcon) is super easy but some places ive been are super soft sand and steep beaches. I will be heading to the NW in the spring and next year to SA and back so will be heading a long way into some very remote beaches. 

@D'train, Rig, Deckie and Makai. I was thinking of staying away from the breakback as i just unhook it and tilt the trailer with such a light rig but i have always been a fan of the drop down wheel setup. have seen people surf launch some big RHIBs with that system. Also nice to know that there is a full spare hub assembly sitting there should the need arise. The other option is drawbar extensions but ill have to check hat it will come in under weight with that. 

Ill update tomorrow and see where its all at. 

I found the folowing two youtube clips last night of a great looking offroad boat trailer. Super high though. Mine wont be that high as my tyre profile is standart zuke not big 4WD.   I love the zuke shocks he has used. looks like a smooth riding trailer built for getting tinnies to those special places that dont even have names yet.

Tight lines

 wow they really are in administration. I found it a bit hard to believe. Will just inspect the hull thoroughly, all welds etc before handing over cash. Just glad I wont be too late to get what i think one of the best tinnies manufactured in Australia. Pit that the workers there who made a great product with attention to detail are the ones to suffer. 

Couldn't be bothered reading all the posts here to see if this has been said yet or not.

1stly, it doesn't matter what size wheels you use, as long as the outside diameter of the tyre is the same. 2ndly, the spare on your car will be useless to you unless the stud pattern of the hub is the same & the wheel offset is compatible. 3rdly, you want smaller wheels with bigger tyres so you can let the pressure down & get them to baloon out so they float on the sand better creating less load on your car & less potential for getting bogged. 

You are right about getting the track the same so the trailer tyres sit in you car wheel tracks. This makes sand towing much eaiser.

I've been doing beach launches for yrs. Personally I'd save the money you put to getting a custom trailer made & put with the money you could get from selling your car & buy a better 4x4. Why do ppl insist on trying things in cars that just weren't meant for it? I've got a diff locked Patrol with 4" lift & 33" tyres. Mate I pull blokes like you out nearly eery time I go on a beach. Nothing wrong with owning a Jimny but planning on taking it to some of Australias most remote beaches fully loaded towing a tinny & expecting it to make it is pure insanity I'm sorry. For your own sake take some maxitrax, a shovel, eprib, a lot of rope, preferably a winch & a few bottles of single malt scotch. At least if none of your recovery gear gets you out you can temporarily feel happy about it. 

Just a tip................if you can raise your tow ball at all by flipping the tongue upside down or something then do it. It might make your prop sit a little closer to the ground but it makes beach launching a lot easier. You can always trim your motor up more to compensate anyway. Or get a break back trailer.
