Hi Everyone,

I was planning to take a Grady Marlin, with F225s, from Newport RI to either Block Canyon or Atlantis canyon.( weather permitting) this late summer or fall. My understanding is that this is about a 100 mile run. I would plan to spend the night trolling and drifting , then trolling some more in the morning and then head back to the barn. It would be four guys, ice bait, gear, etc.

I was curious if posters here agree that the 300 gallon tank would provide enough fuel to make the run.

Thanks for any input.

Looking at the F250 performance data on the GW website and assuming the F225 is close in performance, here is my totally unscientific WAG.

I would estimate 1.14 miles/gallon, but will use 1.0 (not that low at any RPM speed). Assuming a 200 Mi trip, your looking at 200 gallons back and forth. Maybe another 40 for trolling? So, I'd estimate 240 gallons based on this super crude method, leaving 60 gallons or 20% reserve. Maybe bring 15-20 gallons in 5 gal jugs to be sure?

I would figure on 1.0 nmpg on 270 useable gallons of fuel (90% of your 300G capacity).

So, you will need 200G to get there and back then have 70 miles to troll ( not 80, 90 or 100).

I run a 330 with F250's and kinda know what these V6's drink. The 300 will do better than my 330 but not by much. At 100 miles out, I'd think about carrying an extra 30-50G in portable tanks to siphon in just to be safe. Good luck!

I fished a tournament a couple years ago. We went 115 miles offshore.
Here are my planning numbers:
Run out: 3500 rpm, 5 hours @17 GPH = 85 gallons
12 hours trolling: 2000 rpm@ 6.3 GPH = 76
Run in: 4000 rpm, 3.5 hours@22 GPH = 77
Total plan: 238, 62 reserve
We did better even though the boat was loaded with 4 big guys, 8 rods w/50 wides, tackle, fish box full to the top with ice, 2 large extra coolers filled with ice; three cases of water, two cases of beer, a full bottle of single malt scotch, a full bottle of Makers.....so we were heavy. My Marlin with twin F250s gets the exact fuel flows Grady White predicts.
Bottom line: you will have plenty of fuel unless you go crazy and run wide open.

Fall run out of RI to the Canyons !

Plan to expect any weather (seas) on the way home, even if you cut and run early.

How many hours is it going to take at what speed over ground in such conditions, if it turns, from any direction inclusive of north, or east.
Will you be able to keep the Marlin on plane?
What is minimum planning speed for that hull as to be loaded ?

250 gals is the right number. Watch the flow scan. They r right on

I would follow the 1/3 rule - take total tank capacity, reduce it by 10% to subtract estimated margin for unusable fuel and then calculate your total range based on estimated fuel use with a fully loaded boat (ice, crew, gear, rafts, etc) where you then allocate 1/3 of usable fuel for your trip out, 1/3 for your trip back in and 1/3 for reserve; do not forget to factor in idle or trolling time; end of last season was about 65 miles south of jones inlet where I got 1.8 - 2 mpg fully loaded down for offshore (twin 150s on my CC) on the trip out and then with a 2 foot increase in seas and tightening of the wave period (time between swells) I got 1.0 mpg on return trip - I was fine because kept 1/3 reserve - in my opinion this rule needs to be followed and/or combined with safely bringing some extra fuel; keep in mind you'll also see MPG increase slightly as you burn off fuel too - better mpg on return trip

Good luck and safe travels

Thanks again for all the great feedback. This will be my first year fishing RI and having the Marlin. I plan to make some shorter trips before attempting the run and spend some time running it. I have fished for BFT off of Mass about 30 miles or so out on a 22 foot boat regularly the past five years.

Planning potential fishing trips are a nice distraction from the snow.

Thank again.

It's 70 miles from Montauk point to The Fishtales. My 98' 272 Sailfish has twin OX66 injected 225's running at 25-27 mph on a fairly calm early September day I burn 19gph. We can't make it safely without refueling at Montauk.

I am having serious thoughts about purchasing a 5O gal. bladder, filling it at Montauk and running it dry on the trip out. Our boat is equipped with a 6 person raft, 4 immersion suits, EPIRB, personal EPIRBS, Solas jackets etc. but the low fuel thing drives me bananas.

I WISH I had 300 gal. of fuel capacity instead of 200 ( which we all know is safely 150 :bang )

I was considering refueling at Block but I thought it might be too early in the trip. I was also considering stopping at Mntk LI but I wasn't sure how easy it was to get in and out and how much extra time it would add.

Montauk refueling is easy, several choices for fuel just inside harbor entrance. Deep water across sound and inside.

I ran a 2003 306 Bimini with F225's for 6 years to the canyons. Home port is Portsmouth, RI. Safe range is anywhere from the Dip to East Atlantis.

Now not safe range. We would load up with 1000lbs of ice, 19 rods, 5 flats of bait, all the gear and then put an extra 110 gallons on the deck. Fished as far as 10 miles south of Hudson and two years ago made 3 consecutive trips way east to Gilbert. Most fuel ever burned in a 40 hour trip was 356 gallons. That was without stopping at block or the vineyard. My advice is go slow 4200-4500 and not any faster. Make sure bottom is clean or that will kill the gph.

Most importantly safety gear. We had 2 GPS, 2 fixed VHF, 1 handheld VHF, 1 sat phone, life raft, EPIRB, an extensive medical kit (boat owner a doctor), gas generator, and spare everything.

The boat is extremely capable just go slow and be safe

Upgraded to a 2006 330 express and repowered with F300's. Home port is still Portsmouth, RI.

Old boat name Ohana. New boat name is Kraken

One tip on running low on fuel: finish off the front tank first. Early on in my ownership, with a bad fuel sender, I ran the rear tank empty. Thought it was no problem since I believed I had usable fuel in the front tank and had just added about 15gallons just to be safe. When I switched to the front, I found it was all unusable since the boat was light in the aft and sitting lower in the nose than it normally would. The fuel must have been sitting in the front of the front tank and the pick up wasn't getting any of it. I have never gotten that low since, but would always leave the aft tank as my last usable fuel if it did come down to it for this reason.

Thank you all for the advice. My plan is to be docked in Portsmouth RI as well with the name Great Escape II. Looking forward to learning the area and finding the local bait shops, and anchorages spots with the family.

Do fisherman with similar boats to a marlin go from Montauk to the Hudson Canyon or do they traditionally go to Block Canyon? I suspect it's wherever the bite is...
