Powerboat Circumnavigation Possible ?

Beebe's famed Passagemaker for sale

Before he died in 1988, Robert Beebe designed more than 150 vessels, none more famed than his 67th design which he built for himself and named Passagemaker.

The voyages Beebe made with Passagemaker proved his theory that the oceans of the world could be explored in a proper powerboat with greater comfort and dispatch than in a sailboat. The book Beebe wrote—Voyaging Under Power—launched the modern-day trawler yacht era and still serves as its bible today.

+1 Said and done.

I think it is doable.

I think one of the big elements will be fuel costs and these are driven by: speed, displacement and shape of the hull(s). Thus, I would go 'slow' in a big light cat and spend the balance on drinks and fun.

Sounds exactly like cat-man-do only his slow will be faster than most mono sail vessels.

We looked at a Nordhavn when we were boat shopping and they are most certainly luxurious and comfortable, but for us just too small to live on as a home. The one we were looking at was 40' at 350k, so it was affordable. We had to build our boat for a year and a half and ended spending maybe 100k less. I really like the size and heft of a large steel vessel.

Good on you Lorenzo, I'm thinking buying a fishing boat (A Trawler but not as big as yours) and converting it to my needs is the way to go.
How many hands do you need to safely berth your boat in a mariena and what were the all-up costs for your boat?
I, and others I'm sure, would like to see a few/lot of pictures of your trawler, if you have them, before and after pictures would be good

Normally it is just him and his wife, no help needed.

Wow, love Strathbelle! How's the rebuild coming along? Is this is the oldest boat on CF?

[Gene :^)]

Thanks, she is coming along very, very slow.

I think she is probably the oldest on cf.
At 85 ft I think she could be the longest.
Drawing 8.5 ft she could be the deepest.
The 62"x57"x5 blade prop is probably the largest as well.

I'm shopping for powerboats and can't believe how inefficient their hull shapes are compared to sailboats under power.

Average cost of mast rigging, winches, furlers, sails, spi, cleats, etc.. for a 48ft 150 000 $.
Cost of fuel (here in South Africa) 1,3 $ per liter thus with 150000/1.3= 115 384 ltrs.
Consumption passagemakerlite: 4,9 ltr/hr (1,3 US gallon) at 6,5 knots thus about 1 ltr/mile (0,26 US gallon) or 115 384 miles before I could have got any economical advantage of a sail rig. By then of course there would not be much left of my sails or rigging.

The most expensive way from A to B is with free energy.

I like the look of those passagemakerlite/s, the passagemakerlite 39 would suit my needs to a T but alas, I'm not in the market for a new boat, nor do I have the time to build, so I guess I'll keep searching for a suitable older power cruiser.

I fully agree with you. After reading your blog: www.passagemaker.co.za I see you are doing what you preach. May I send you a PM with some specs on a boat I'm looking at?

Sure please do so.

I have enjoyed reading this thread from the beginning. I landed on it from doing a search on Nordhavn because some friends just arrived in Panama today on their 43'.

On to a different concept, diesel-electric-solar hybrid.

If you don't mind a slow passage at 3.9 kt, then the 6 kw of panels will allow it with no consumption of diesel. There is a pair of ultra efficient Steyr 75 hp diesels for a more conventional speed.
