    Hi from the Tasmanian Island state of Australia

    Hi, Thanks for the reply. Our waterways are reasonably clear of obstructions but in saying that it's still an ocean and things still float about in it. We had a safety warning for mariners alert that a 100mt 250kg (300ft - 550lb) piece of black PolyPipe from a local marine farm had broken...

    Running a Sea Ray 275/260 at say, 27 to 37mph for 5+ hour runs

    Hi and thanks, Yes, I have very good sailing experience and with that, I'd like to say excellent navigation skills and weather awareness skills. I guess to clarify 'outrun' is that I'd cruise to the appropriate weather but should weather look like it's turning for the worse either by our...

    Running a Sea Ray 275/260 at say, 27 to 37mph for 5+ hour runs

    Thanks for the info, Tasmania is situated in the southern ocean with huge, no, HUGE westerly swells (Google Marrawah Tasmania to give you an idea of Tasmania's rugged West Coast) thus, I'll be staying well clear of the West Coast and limiting my cruising to the much calmer Eastern side of...

    Running a Sea Ray 275/260 at say, 27 to 37mph for 5+ hour runs

    Hi all, Thanks for the wealth of good information. I've formulated some data and using Navionics my maximum run at 27mph is just over 3hrs at a fuel consumption of approx 173L. This is a good safety margin of fuel as each of my ports of call have fuel docks available. Plus running Unleaded fuel...

    Hi from the Tasmanian Island state of Australia

    Hi and thank you very much for the excellent information. I like your answer as it really offers me 'real' data, I think my math's is good so I have trust in my calculations of Litres per Hour and balanced with what your information I'm thinking I can do a 5hr run. I was also concerned with...

    Hi from the Tasmanian Island state of Australia

    Hi Tony, Yes, Tasmania is a lovely piece of the world but then again, I believe most areas that have an ocean or coast are also lovely pieces of the world but that's the boater in me. Wow, sounds like a good month of travelling. Devonport for the Spirit of Tasmania Ferry and the Salamanca...

    Running a Sea Ray 275/260 at say, 27 to 37mph for 5+ hour runs

    Thanks, some really valuable information. Is 75% of WOT a good cruising speed? I'll get into more forum searches and have a more detailed read of some posts.

    Running a Sea Ray 275/260 at say, 27 to 37mph for 5+ hour runs

    Thanks for the reply, I really had no data to go from. I did find some fuel consumption data in Litres from Boat-Fuel-Economy website which had the Mercruiser 5.7MAG - 300HP @ 1500rpm = 9.5L 3000rpm = 28.5L and 3500rpm + 37.5L but I'm unsure how accurate those internet figures are and would...

    Running a Sea Ray 275/260 at say, 27 to 37mph for 5+ hour runs

    Hi all, from Australia I've just joined and would like to ask! Is there a fast rev/speed that can be sustained for say, 6 to 8 hours? I've read that 6-8knots is ok for fuel economy but I'm thinking of fast 5 hour runs at say, 15knots/27mph or even 5 hours at 20knots/37mph I live in the...

    Hi from the Tasmanian Island state of Australia

    Hi all, My name is Pete and I'm from the Australian Island state of Tasmania aka home to the Sydney to Hobart Yacht Race and largest wooden Boast festival in the Southern Hemisphere but enough of the tourism ad. I've nailed down my Search to Sea Ray's Sundancer and most likely a 2006-2008...
