I know I'm a little late joining this party and to be fair I do have a boat that cruises about 17 knots. I prefer this because if I have to get someplace fast because of weather or other I have the ability to do so. We go to the Bahamas cruising at 17-18 knots and once there usually go at 7-8 knots. Once we were almost to Georgetown when a hurricane made a turn and headed to where we were, we left early in the morning, stopped in Nassau for fuel and continued on to Chub, next morning we left for Miami. Speed was a wonderful thing to have on that trip.

My old Viking will still do it's advertised 27 k. At that rate, it's burning fuel like a DC-3. 13-14 k is a comfortable "cruising" speed if you don't care about fuel burn.

Normally - trawler speed (7-8k). Able to sneak up on wildlife and hold a low decibel conversation, while sipping fuel. If I had a little more rudder surface, it would be perfect all the time. As it is, as long as I don't have a following sea, we do trawler speed.

Quoting (I think) from an old Greyhound ad - "Getting there is half the fun." Or more.

Wifey B: Rode one horse power means of transportation today. Walk at 4 mph, slow trot around 10 mph and gallop around 25 or 30 mph. Rode about 3 hours. Fuel required was some hay, a couple of carrots, some feed and about 2 gallons of water. Very efficient.

Yes, but the labor maintenance costs or personal hours, is exponentially greater than most boat engines.....and then there's mucking out the stall. Like so many things, better to rent than to own.

Other considerations - one or two engines? I am not a fan of an aft cabin where the cockpit is raised. I like the cockpit at water level, with easy access to the swim platform. Well, where do I go from here? What boats should I be researching? I am thinking 43 to 50', and controlling price with age of boat. Price is kind of up in the air, but I would think at least $300k, with room to go up if I fall in love with the perfect boat, a Unicorn.

Thanks again for all the input.

You can get everything on your list in a Cheoy Lee trawler. The original ocean going trawlers. But they are scarce as hens teeth.

Wifey B: Or just ride at the grandparents of a friends home in Spain. They have acres and acres and stables and pastures. We have city sized lots in FLL.

Tomorrow we get out on the water. Never been on the Med.

Only two days on the water. Boat on water has 7200 hp.

Check with your trany mfg to see if free wheeling in OK.
I never thought about the transmission when running on one engine. I guess I better look into this now. But, I was always concerned about free wheeling melting the shaft seal. Especially if you don't have a crossover hose between your port and starboard shaft seals, the spinning shaft will burn up your ahaft seal without having the water to cool it down.

Melted "dripless" shaft seal will likely happen if you have dripless shaft seals. I stopped using those many years ago due to failure potential of sinking boat as well as no free wheeling without heat damage when there was no functioning crossover hose... which, when crossover is installed, creates another "dripless seal" failure point.

You can always lock tight the shaft from non running engine. Locked prop creates a bit more drag than free wheeling prop. Also, will take a bit of time/effort to lock the shaft so it can't get loose - plenty of inventive options to accomplish that. You might be lucky and invent a simple, quick action, fool proof and affordable "lock-it-tight" shaft binder that can be patented and sells like crazy! Only one I've read about costs a bit, some effort to install.

I agree that when the engineers converted actual horse power to engines, they underestimated the efficiency of a well taken care of horse!

Can you just put the transmission in gear? Surely the compression will keep the prop from turning.

I needed to lock the shaft one and used a large vice grip to lock down on a two inch sharft and tied it off with some 1/4 lines. Did over 200 mikes with no problems. Easy fix.

Going slow

I love cruising at 7 or 8 knots, much more enjoyable, and the boat is "liveable" while cruising.

However, I can only do that alone or with buddies. When "Admiral" is aboard, its 16-17 knots, she want to get there!

The exhaust was a problem when he fed the horse Beefaroni IIRC

Art, "appropriate", in one of its meanings, would be more, well, appropriate, than abscond. But as a true grammarian,Al resisted adding "with" after "abscond", which might have worked but would offend by ending the sentence with a preposition...

"Locked prop creates a bit more drag than free wheeling prop."

Depends , multiple experiments have given multiple results.

A locked prop is easier on the tranny , shaft bearings and stuffing box .
