Biteme-fuel burn

[Libero]

Biteme-

With the 315 Yanmars what is your fule burn on a typical 75-80 mile canyon run?

I am interested in performance figures with your engine combo.

Thanks,
Nick

Hey Nick, what are you doing over here. Are you looking at a Classic?

Did you sell your shammy yet?

i had a bad season last year due to personal issues..we made a few day trips to the tails which is 70 miles each way..i think the burn was @160 with 24-5 knot runs each way and a full day of fishing..may have been less but not more..made a trip to the dip at @ 140 gal.. my mechanic balks at instaling flowscan for fuel rest. proplems...this tear boat will get full ovetnite trips as soon as the fast fatties show their pointy heads !!!

Hi Tom-

No, I did not sell my Shamrock yet but am considering a 28 CC 1-2 years out. I figured I better start looking now to see whats out there and learn more about the boat.

I really want a 28 CC that can cruise at 28-30 knots. I am hoping to get about 1.5 NMPG too. Other than the Yanmars, I think the Cummings 330 engines would do the trick. I do not want Volvo's.

I was at the Miami show and talked to Kieth Privot, what a nice guy. My fiance really liked the boat too. We both want something that is a little more comfortable for the couple of trips per year that she comes with me offshore.

I also like the layout of the Rampage 30, Shamrock 29, Henriques 28 and the Pursuit 30 Offshore. Does anyone here have any pros & cons comparing these boats? I do realize that hull design is a tradeoff among these models.

Any advice would be appreciated-
Nick

Nick I have an 04 28cc with the 300 volvo's I cruise 28-30 kts burning 18-20 gph, I was a little hesitant with the volvo due to heresay, but I've made 5 trips last year to the hudson canyon from staten Island NY, and the boat ran flawless.I spoke to Mac about the yanmar vs. volvo and he told me its up to the buyer, he's view was that they both run identical as far as speed and fuel burn, the differance electronic engine vs. mechanical. Electronic engines are the way of the future. I look at a 28 with the 330 cummins , if your 4 feet tall and weigh 75lbs. great cause if not there is about zero room for you to get in the engine room.As far as the other boats you listed I never looked at them except the Henriques which I did not like cause of the mod. vee then again theres a tradeoff mod. vs. deep.A friend of mine has a 00 30 pursuit offshore with volvo 44's nice layout to the boat but as far as performance a total dog the boat is very under powered 21kt cruise 26kt. wot

I too am hesitant of the Volvo's due to the heresay and also due to the fact that the parts are much more expensive. Kieth Privot suggested that 2 NMPG is possible with the 260 Volvo's at a 25-26 knot cruise. Is that a full load estimate?

I agree, it is smarter to buy newer technology with the common rail setup, etc. Do you know what the life of the Volvo's are? I know that the Cummings have a long life if taken care of properly.

Thanks,
Nick

Keith is talking about the D4 volvo with the common rail, I have the volvo 300 which is really 285hp, my personal opinon is the D4 and cummins 250 is little underpower, the volvo 300 or yanmar 315 is the best set up in my opinon.The cummins 330 is overkill, again my opinon.As far as longevity I don't know, but the saying is, use it or lose it.Like I said in an earlier post fully loaded , that is 4 guys,full fuel 400lbs. of ice and the fishing gear to the canyon 28kts, 18-20gph, 8hrs of trolling and back home total trip 180-185 gals for the day.As far as the heresay, what sold me was the dealer gave me the extended warranty.Volvo got a bad rap on there eairlier engines that is 41,42,43 series but before I bought my boat I suscribed to boatdiesel.com and couldn't find a single bad thing about the volvo 300 only possitives, and that also swayed me.

Nick, I went through the same thing the last 2 yrs. When I go offshore I want the best riding boat that I can find with the most room. I started with the Henriques( and almost bought one) until I looked hard at the bottom. It looks to flat for a good ride. I talked to a guy in Long Island that had one and he confermed this so I bumped it off the list.

The Rampage and Shamrock is the same hull. Why one is 29' and the other is 30' is beyond me. I own a walkaround as you know and will never buy one again. Any water that comes over the bow fills the boat. Not a good design for offshore and you loose to much cabin space. They have lots of room because of the 11'6" beam. They are cored on the sides which I do not like. I want solid glass for lots of weight.

The Classic is solid glass, weighs 13500 lbs dry and has a 24deg bottom. Much more at the entry. People complain about the rock but my fathers 31 shamrock rocks pretty bad so I'm used to it. It's a tradeoff I am willing to take for a good ride.

As far as engines go, I'm a cummins guy so I would put in the QSB 330 commonrail and would have Mac add extra fuel tanks which was discussed in another thread.

Here is a picture of the bottom just in case you never saw one.

I'm going D4

repowering now from KAMD 42's to D4's after a lot of back and forth. Mac finally sold me on the D4's when he put a set of 18 X 26 props on them and got within 1 knot of the KAMD 300's and yanmar 315's.

My canyon run is 20 miles more than from N.Y. and to me being able to cruise at 25-26 knotys/18 GPH is more important than a 28-30 knot cruise.

We'll see when the boat is done, but Mac says he got 28+ knots at cruise w. the D4's; full fuel, 3 guys and 300# of weight on the deck and still hit 3630 RPM's at WOT.

One other (editted) point on the D4's - their torque curve is outstanding and shows top torque is reached at ~2000 RPM's - this hopefully translates into another key element of fuel burn - how the engines handle variable load at slower speeds and lower RPM's. My old KAMD 42's burned almost the same fuel at 3000 RPM/20 knots in heavy seas as they did at 3300 RPM in the same sea conditions. The mechanical governors were always 1/2 wave behind the boat and would end up surging and retarding the RPM's by up to 200 RPM as I went up and down both head and follwoing seas.

Hi Gang-

Tom: I know what the boat looks like quite well, our summer home is about 300 yards from Holiday Harbor Marina in Waretown, NJ.

Actually, my 24.6 Grand Slam looks identical underneath, just several feet shorter and a foot less beam. The model of my boat is rare, they only made it for 2 years.

I think the short list will the the Blackfin 29 and the CC 28. I need at least 240 in fuel on either boat. I do like the Cummins better, but I am warming up to the Volvo's. I also think that 290 HP is the least I would buy for my needs. I also would like to get a genset and heat/ac if possible. A new boat is not in the gameplan, I think a 2-5 year old boat would be great.

Has anyone ever thought about building in a folding bunk on either side of the cabin area where the shelves are? That would make for a 3 or 4 person bunk setup. Rampage/Shamrock is the only vessel in this size range that has done that. To me, it is a nice to have option.

Thank you for all of the replies so far, this thread is helpful.
