See if you can get a deal on the optional extras because its all the upgrades that add up. Make sure it has trim tabs fitted, that are a must on Bar Crushers. Also a Barcatch, but they might be standard now....makes life easy at the boat ramp.

 Cheers for the tip about the optional extras.

 Plenty come up for sale in karratha .. they do seem very expensive for what you get 

Cuts a good deal and yeah boat show specials will save some coin, definitely go trim tabs and bar catch. A couple of free services is usually easily negotiated on top of putting the squeeze on the electronics.

 make sure you have a look at the trailer as well. Seen plenty of good boats sitting on rotten trailers.

 if you are looking at a " deal", it is very common, unfortunately, for costs to be cut by placing a trailer which is really too small for the boat under it. It may be technically marginally OK as the boat leaves the dealers' yard with no fuel or gear on board, but fill the tank and put even normal safety and fishing gear on board, and it is overloaded. There was thread in here only a year or two back where the dealer ( this was in Perth, I think it was the Barcrusher dealer? ) did this--when the owner took him up on it, he said that you are not meant to fill the fuel tank right up    True story. Make sure there is plenty of margin , gross weight-wise, over the dry hull and motor weight. 

 Get them to throw in anchour, life jackets, epirb, flares, a plumbed up live bait tank, have a look at the optional seats, twin batteries, optional engines, even decal stickers and all of the above, i would think the way the economy is they would be willing to do a deal. Boats are similar to cars they have a there cost, mark it up and you try and get as much extras out of them as you can barter for

 Sethy, i have a 6.8wr bar crusher for sale,  as new , i  have just purchased a 8m Preston Craft , needed a bigger boat for the family,

  so the bar Crusher has to go,( Gumtree add gives detail)   call me if your interested, 

and good choice of boat, i would have to say its  the best riding boats  i have had over  years...   regards Frank

 My biggest advice for buying anything large capital item new is KNOW EXACTLY WHAT YOU WANT before begining negotiations.

If you are well researched and know exactly what you want, then you are in a position of strength and the negotiation can be on your terms. If you are pliable then you are open to manipulation with things like trailer quality and the other stuff mentioned above.

It seems like you are not quite ready and it might be best to use the boat show as a research exercise. These sellers all say stuff like boat show special and deal expires at the end of the boat show, but in the reality in todays market you should be able to secure a similar deal even after the boat show. There is not a lot of toy money floating around in WA right now and these dealers want to sell so will cut a good deal.

I reckon try to narrow it down to a couple of brand/models and figure out a specification as close as you can, including options like engine, winches, electronics, plumbing etc. These items are expensive but there is a reasonable profit margin at retail prices. Quite often dealers will add the options in at near cost to get a package across the line. So when negotiating know the retail prices of electronics etc and try and get them down by 20-25% which will be down near cost.

Also if you know exactly what package you want exactly, you have the option to just shop the exact package around between dealers even nationally.

This is how I purchased new cars and it soon sorts out who is competitive and really want your business. Sometimes with cars there are rebates from factories on sales numbers and your sale in the one they need to obtain the rebate... Not sure if this applies to boats

Anyway that's my 2 bobs worth, I hope it helps. Good luck!

Purchased my bc over east at a much better price, wacked a 1000hrs on the motor and sold for 8k more than what i paid.
DO not buy a single axle trailer for a 615 and if you can afford it, try to get the max hp.
Buying a new bc is quite expensive but they shit all over every other ali brand in performance imo.

 Whats wrong with the single axle trailer. Arent they "custome made" for the hull?

A single axle trailer is a cheaper option, there is nothing wrong with using one, but the advantages of a tandem outweigh a single significantly imo.
Long story short, my brother and I use to own a 615bc each, he had a single axle for two years and never gave it a second thought. When I bought mine from NSW he drove it over to WA. We sat down over a beer and he commented on just how good it towed with great stability, he also said he had a hell of alot more confidence whilst towing it.
He got back home and sold his single axle trailer and upgraded.
I was lucky enough to have got mine at a great price with plenty of upgrades that bc offer.

don't rush... And make sure you give any boat a good test run in below average conditions.... Most boats go good on flat waters.

Take your time and really consider what you want in a boat now, and what you may need it to do in the future (kids getting older etc.) As said above once you have settled on the boat you want you can stand firm on the extras you want with the deal, the economy is slow at the moment and to get the sale I believe the dealers will be quite flexible so don't be put off by the "no" we can't do that response. But at the same time don't be foolish with what you want thrown in with the deal.
Have fun with your shopping and let us all know how you went.

i don't consider myself an expert. ( particularly after just launching my new rig onto the concrete boat ramp)

but I do talk  to a hell of a lot of fishos and do my share of boating.

my understanding is there is a lot of hype around Bar Crusher.

 Great name, and a very nice boat, but do yourself a favour and try not to get caught up in all he hoo Har around a particular brand.

the other thing is + 100 for Ranmar 850 trailer comment, many years ago I got caught with a Boat Show special which was on a crap trailer....I didn't have enough brains to notice as I Was all psyched up with getting a new rig at the time ( it blinds you), trailer was way too light for the rig, with no brakes, and the bloody thing rusted out completely in 4 years! ( Dunbier) And eventually it also came to light that the fixtures and fittings were slapped on for the show ( It was a display boat)

eventually got all sorted, sold it.

oh.....and the first boat you buy will certainly NOT be the one you end up with.

good luck and enjoy the hunt.

 Thank you to all for your advice, Decided on the Bar Crusher 615c. Many of the words above were helpful in providing comfort for my final decision. The boat is on show at the boat show at the moment.

 Another trick (similar to the trailer one) to make BMT packages attractive price-wise is to put the minimum HP motor on it. Yes it's legal but you want to be able to load the boat up with crew, ice, gear etc and still have reasonable performance, and you don't want min HP when things turn nasty on the water.

My general suggestion is to fit the engine size one smaller than the max for the hull.  You may also find that a bigger engine under less load will use less fuel than an overstressed smaller engine.
