We had à system to "lock' our shaft on our Cheoy Lee 53, it was like à car disq, it was locked when the key of the engine was in stop and it open when you start the engine. Are you sure than à locked propeller do less drag than free one ? Fre ch désigner Joubert on his motor sailor...

The différence between steel and aloy for the hull of our former Long-cours 62 was.. +10 T (for an average similar résistance) it is à hudge différence ! 15 cm more draft and...15 cm less free board and need at 10 kts 34 % more hp

At less you must start the engine each 3 hours for lubrification, ( or switch ps to sb each 3 hour) it is what they say on the documentation. On our former boat the hurtz don't need this regular start.

On 140 nm at 7,5 kts we was only on one engine running at 1100 rpm !! Fresh bottom paint, and full of equipment, tool, water but remain "only" 3500 liter of diesel in the tank It means we was at an average of 58 T We fill 5.8 m3 of diesel in Tunisia, now remain around 7m3 and our actual weight...

We don't check at 8 kts At 7,50 kts it was 2 liter per nm it is around 1.89 nmpg checked on a crossing of 140 nm At 9,85 kts it was 3,85 liter per nm it's around 0.983 nmpg checked on a cross of 240nm

This C12 are electronically injecter. But not only aluminium "trawler" was made for speed over the hull speed : Grand Banks,Swift, Nordic Tug, Rhea, Fleming, Adagio...etc All this fiberglass "trawler" have more hp per T than our. I contacted Cat to rated our 700 hp tp 350 hp ( like the...

Few year ago I bought this one, ok not à kayak but It work well without effort.the bl-3 model https://www.koga-miastko.pl/koga-small-sailing-equipment.html They also built lot of type of kayak

Yes impressive but in witch way ? :) At 8 kts 1.42 liter per nm it is 24% more than our former boat At 9 kts 2.94 liter per nm it is 65% more than our former boat at 9.8 kts I like the concept of this boat but can't say the consumption is the main argument :) On their Atlantic crossing they put...

I always put the "real" ( from surface)because : nothing to do for my old brain ( until I still remember my ...draft) for example a "bathymetric ligne " of 20 m just looking 20m ( eventually corrected by the tide at this moment). not need to make plus to the keel or plus to the transducer.

Are you sure all is well fixed in the propulsion line ?

Thanks for this info, but little desapointed Our former Long Cours 62 doing better at this speed, may be they running generator ? 6kts was 0.68 pnm 7 kts was 0.81lt per nm 8.4 kts was ( full (over) loaded at 34T and just launched with fresh bottom paint ) 1.38lt pnm And Long-Cours was not the...

Domino is one interesting catamaran closer to my "dream power cat Santorini" than the too high, too heavy, too low bridge standard powercat. And Domino have a similar consumption than our former LC62 it means near...half than the actual at 10kts :-) Domino is all I like in powercat small draft...

Interesting to know the consumption of this one at different speed ? https://www.yachtworld.com/yacht/2012-custom-78-transocean-powercat-8699533/

For the moment the last offer we got was not "reasonable " for us 325000 :-(. If nobody interested it seams we will miss the opportunity to buy back (again !:-) ) our Vietnamese baby

I like the retro look of this motor sailor ( if it will be not me who must do the varnish ! :-) ) But I don't understand this amazing high diesel consumption !? 6/7 kts = 7 to 8 gal per hour !? It means average 4.35 lt per nm I think mistake between gal and liter ? Because 4.35lnm it is more...
