215 CC with a 150 yamaha Range

[djdecuollo]

I have an 07 Triumph 215 and I want to take her offshore some but I have no idea what the fuel range will allow. Anyone take their boat offshore and how far out would you say is a safe bet with fuel to spare.

All and any help/input would be greatly appreciated!

DJD,

Rule of thumb is use 1/3 of fuel out, 1/3 in, and 1/3 contingency (you don't want to run out of gas in the ocean...it can cost you big!). Capacity is 70 gallons, depending on how your boat is performing, weather conditions, weight on boat, your engine model / HP, etc. you may be able to achieve a 200+/- mile range. I would start by doing some lite off-shoring at first (5-10 miles) and collect data on your trips (the owners manual has a chart that you can collect info). You can estimate from there.

There are several factors you need to take into consideration when estimating your range. First your fuel consumption under optimal conditions. For example, full load of fuel, two people, normal gear, keeping the throttle at a cruising rpm and that the seas are flat. Hence, something that never occurs lol. But to give you and esitimate my 210 with a honda 150, has about a 210 NM range. Using the rules of 1/3s, 70 miles out, 70 back and 70 in reserve.

Thanks guys, I was thinking of a safe bet being 1/4 tank out then 1/4 tank for trolling and such then 1/2 tank to take me back in. The real advantage I am lucky to have is that the gas pump is about 1.5 miles to the ocean.

Like an Aircraft, I would not think of in terms of range in miles, as much as in how many "hours" (time) the engine will run at any given RPM speed before running out of fuel...

Most of your modern outboard engines though will return their best range (if the right prop is installed) right around the 3500 to 4500 RPM mark. Much faster, and you are burning fuel at a much higher rate for not much gain in either ground speed or in distance gained. I like the 1/3 rule of thumb myself, but if in calm water and if you are not in a rush and willing to run a good cruise speed in and out, you can more than likely add another 30 plus miles to that range...

Fuel flow meters though are great for such work for you can watch how even slight changes in trim can effect your GPH (time in the tank) burn rate. Then compare it to your GPS too see if you will have enough fuel (burn time) to make to your spot and back. This for backing down even a 50 to 100 RPM at certain speeds, can drop fuel burn by gallons per hour pending how fast you are running of course and with the cost of such gauges going down http://www.boatersworld.com/product/319393112.htm
having one installed will pay for gauge at 3 plus dollars a gallon of fuel soon enough

Distance Offshore depends on boat traffic for me. In Charleston, SC there is a lot of traffic so 30-40mi ( I've been 45 but spent too much time worrying) and l feel safe. In Beaufort, SC 20-30mi is a stretch. 460 is out of range, though I can hear the Marinas. I want to reach someone else offshore.
