fuel efficent offshore boat

Panga 26'

The most fuel efficent offshore boat that I have ever seen is the 26' Panga built by angler, I work at an angler dealership and I hear they get 10mpg and take rough seas as well as anything in their class. They come with a 1.7L cummings and top out about 30mph. Their base price is around 32k, and they come with a lifetime warenty. If anyone wants one let me know and I'll put you in touch with my boss.

 

OK I ran 31 ft jc boats in the gulf of mexico, with twin turbo 210 volvos and duo prop out drives, 6000lb payload 1000 lb gear,we got ,,,,at 3to5 ft seas and at 20 knots 1 gal per hr diesle consumption, they are semi displacment semi planing hull contact jc boat in new hampshire for details or look in old national fisherman mag era 1980 to 90 under paul pence ,,,,braodbill 1 and 2 and tochea......longliner

 

Sharpie designs

Phil Bolger sharpie designs are relatively easy and inexpensive to build. Likewise, they don't require a lot of power to move them. Key to sharpie effiency is keeping the stern out of the water. This reduces drag. Sharpies are not particularly good seas boats,but are great for inland work.

 

Check out the design in the June edition, Number 190, Wooden Boat magazine entitled 'A High Efficiency Kiwi Cruiser' designed by Peter Sewel of New Zealand. It's pretty interesting.

 

The Ruel Parker 36-ft Commuter is a good design for your criteria. An aluminum version was built in Nova Scotia and launched in 2001 that has cruised extensively and trouble-free since then. The owner does a lot of coastal cruising and has taken the boat from Chester NS to Cape Cod and back. It is powered by a Honda 90-hp outboard and cruises at 17 knots with a top speed of about 21 knots. It has a 250-mile range, sleeps four, has a full galley and stand-up shower. Since the photo below was taken, it has been fitted with a bimini top and Isenglas side screens to extend its cruising season from early spring to late fall. The owner, a former blue-water sail cruiser, is very pleased with his boat.

 

Wow! That boat is REALLY skinny. Won't she roll horribly in a beam sea?

 

In a word, no.

In reality, her roll motion is very comfortable - not quick and snappy like a beamy hard chine hull; more like a sailboat with a gentle, long-period roll (her roll period is about 2.2 seconds). Of course, if you come to a complete stop or travel at very low speed in beam seas, it will happily roll more than you'd probably like, but with any way on at all she is very stable. I've piloted her in short-period beam seas of about five feet height, and her roll isn't more than about 10-12 degrees across the full arc of roll.

 

I would skip the outboards if economics due to fuel price is a consern.
Why not two steyr diesels in aluminium? light and economical.

 

It is a very nice coastal cruising boat, but it doesn't seem to me an offshore cruising boat.

 

mmd
I like it alot, especially with fuel $3.30+/Gal.

 

You mean that the consumption of your two 210hp engines with 3 to 5ft seas, doing 20knots, is 1 gal/hour?

 

On a tow line?

 

maybe 10mpg at idle but 6mpg is what I average at a 25-28mph cruise (3500-3800rpm)... The do ride amazingly well..

 

Only two things come to mind that i would call sea worthy. One would be a displacement catamaran, like a converted sail boat the other is the Panga. Not a US panga but a south american Panga built to the dimensions/weight of the Eduardono boats. 28ft eduardono runs right smartly with a pair of 45hp 4-strokes. The american version have too much fluff and weigh twice as much as the standard Eduardono (actually owned by Yamaha). Panga.com boats come from this company I believe..

I like that commuter posted above in a center console. The long narrow approach makes it look a lot like a panga in the length/width area.

Weight would be the big issue. Stitch/glue panga like bateau.com might be getting close..

 

Any boat that is 3X as long as it is wide is NOT a Skinney boat, so if fuel consumption is low its from light weight.

Once the L is over 6 times the beam the wave making resistance goes way down , and economy is the result.

Unfortunatly slip fees are on overall legnth so the 12ft wide 65 ft boat (8ft BWL) may have fantastic fuel consumption and great deep sea handeling , but there won't be much savings unless she is at a mooring.

And the local $3.00+per ft for an overnight dock would be a killer!!
