I've got the Oceanrunner 670 with a 150HP Yamaha on it. Could do with a 200HP i reckon power wise but i can still get to about 28-30Knots with it. I have to trim the motor right back to get a good ride, probably could do with a bit more weight in the rear. Nice and dry with the hard top. Heaps of deck space and is great for trips across the Abrolhos. It can rock a bit side to side depending on what way the swell is coming from, definately need to have trim tabs. Overall a good boat

 Thanks for the feedback, the boat I am looking at has a 150 4 stroke so hopefully power to weight ratio should be o.k

I have the 670 walkaround with 200HP 4 stroke.
It goes pretty good, tops out at between 35-40 knots (tweaked 41 out of it on glass-offs).
Stable at rest, we fish 3 blokes one side no worries at all. Cabin is big enough for the missus and kid to curl up in.
With the 620 I reckon the 150 would be OK, maybe a little slower out of the hole, but that's not really an issue for fishing or diving.

 Hi bsir,

Thanks for your response, you are correct the speedout of the hole is not an issue for me.

 Skull I have an under powered boat and ALWAYS wich it had a bigger donk (bad choice of words there) you know yourself it will bug you for ever as the boat will not perform and the extra fuel trim trim trim.......

Thats my thoughts anyway. Im just jealous Id love one !

 Hi Ol Tom,

I currently have a Genesis 580 with en ETEC 150, I am of the opinion that it is slightly overpowered, what size boat and outboard are you currently running, I respect the fact that we all want to get to our favorite place to fish or dive as soon as we get on the water, but I am a bit of a cruiser and sometimes just enjoy being out in the ocean, what size moter would you recommend for the Coraline 620 walkaround?

Thanks in advance for your advice.

 Skull Im no guru except to say I have a 4.65 trailcraft with a 50HP four stroke. When the mate bought his boat I recommended he put the biggest legal motor on it he could. The trailcraft are a heavy boat and mine can take a 80HP motor. Obviously they put the smaller motor on to bring the price down and I got caught out. 

The boat will do 42km flat out which is usually enough (60-70 would be better) but thats when I am on it alone. As soon as I load the boat up with people and gear it struggles.

My advise is if the boat can take a bigger motor then put it on. Of course there is a balance with initial cost, power v fuel usage etc but the mate loves his boat and it is quite economical. Me...I keep looking to power up, which costs you more money anyway.

I know I havent answered your question exactly but look at the maximum motor size and if the 150 is close then maybe ask the owner for a test run?

Good luck

 I'd put minimum 140 on a 620, or 90 twins. i've got a traill 540 with a 115, which was an upgrade from a 90 (180kg/130 max) and am always looking for more with 31knots max out of it. It's more of a get home/ pull out of the shit asap with motor choice, storms can roll in quick. I reckon i could get a 140 suzi with the weight limit.

Hi Guys,

Thanks for the advice, morgs I think you raise a good point, I never considered twin outboards, I went and had a look at the boat this morning and even the Salesman didn't mention twins as an option, will go back and discuss this with him.

Regards

Skull, I have owned a 670 Coraline walkaround for the past 6 1/2 years, not the perfect boat (there is no such thing), but a very good boat that I expect to keep for a few more years to come. With a 225 Yammy 4 banger hanging off the back it performes quite well.

 The only real complaint I have is it's slighly unpredictable behaviour in a big following sea. It has scared me on a couple of occasions (broached), but the seas were BIG. 

Be carefull of the trailer/boat weight.  Although I did buy second hand, the boat came on the John Pappas 2 tonne trailer as supplied when the boat was new. I put it on the weighbridge and with nothing but the necessary safety gear on board and full tank of fuel the weight was 2.38 tonne.

Ended up costing me 4 grand to upgrade the brakes and suspension to make it all legal. My other bitch is that the 200 litre fuel tank only hold 170litres !

Good luck with whatever you decide on buying, it IS a big decision.

Have had a 620 ocean runner before but would never buy a coralline again good solid boat but very hard ride compared to the current boat and they seem to list too easy

Hi Guys, thanks for the latest feedback, I am interested in the broaching issues withthe boat, this is a topic I talkedat length about with the salesman, he guarantees that with the new and extra big chine this is not a problem, ( can you trust a salesman?).

The fuel tank is another disappointing thing as the brochure claims a 200 litre tank so not having the fuel you think can get you into trouble although we must have a safety factor so as to not run out, but you should at least get what you pay for.

Nathan (catchalittle) what boat do you currently have as you no longer have your 620?

Looks like I willl be going back to ask more questions before making a final decision, the advice from all of you is appreciated greatly.

Skull

Mine fuel tank specd at 200L but to be honest I have never ran it that dry to find out. I calibrate my fuel tank (on the HDS) as 150L and try to work to that. I think I got 170L in it one day after a few outings.

bsir,

Even though i wasn't buying my boat from the dealer, I called them before I purchased it to ask specifically about the trailer. They knew the boat I was referring to and assured me that the weight would come in just under 2 tonne. "Just don't overload it if you do a big trip away and you should be O.K" they told me. Don't believe salesmen !

It would be a good idea to find out your exact weight, as you have no insurance cover if you are involved in an accident. Worse still, if you were to clean some one up because you couldn't stop in time, it's very likely you may have the book thrown at you.

Hi Nathan,

I have heard the surtees give a good soft ride, I currently have an anchor winch on my Genesis, as the Surtees is not walkaround is it easy to access the anchor, as I rarely anchor these days (only when Diving) no need to have a winch.

Skull If your serrious about the coraline ask the saleman to take you out for a test run on a demo boat... in rough condtions then you can make the decsion for your self.... and get the boat saleman can put his money where is mouth is.... IF you worried about the trailer put a subject in your offer to purchase that stipulates a wiegh bridge certificate that your happy to pay for.... 

 Had same problem broaching with trailcraft.

Alot of allys need extra weight (like alot) in the back to stop this.

Chines alone wont fix it.

Id consider your budget and have a close look at some custom boat builders.

 Maybe slightly smaller but with better performance and safety for your money.

Have a look at some westys too. Maybe an older hull with a newer motor might be the go?

Good luck!

 Hey mate, my best mate has a 620 SF coraline. Just got back from 2 weeks in Exy on it. Has the 150 yammy on he back. My experience with different models and especially bigger fibreglass boats aside I absolutely rate it. You certainly wouldn't go smaller than the 150, it tops out at about 34 knots and cruises nicely at 23 using 25L of fuel an hour. Awesome to fish out of. Have experienced the trailing swell problem but don't really have a comparison, would have thought most boats would act similar. Real stable, I had no problem jumping on the roof and sitting while zipping around searching for sailies in the gulf. 

Any specific questions feel free to ask and I can pass them on aswell.

I have a Oceanrunner 580, i have had a hard top retro fitted by Boat City, also fitted a Suzuki 150, a great combo.

Yes the ride can be a little rough in certain sea states, but overall not bad.

As for the broaching..ask yourself if you would be out in those condidtions in any other boat?.....The coraline is built like a brick shithouse, strong and reliable hull, yes with a few ride issues but driven to conditions is a safe and reliable set up...especialy with the suzi four banger on the back.

Love my Coraline.

 Go the Coraline Skull
