Re: Back-up motors

If this is a charter - ask the charter company if you can mount the dinghy motor on the stern to get a few extra tenths of boat speed.

I guarantee you will shortly be told you don't have the experience necessary to charter the boat without a paid skipper.
Displacement boats have hull speeds that can't be surpassed except for brief surfing down a wave. There is a reason they are called auxiliary sailboats - the auxiliary is the engine meaning it's the secondary source of propulsion. The engines are sized to take the boat to hull speed in reasonable sea states at 3/4 throttle.
Ask the charter company what happens with you max the throttle out for more than a brief burst - and tell them you really need that extra tenth of a knot to get to your destination quicker. Same results will occur, make space for a charter skipper.

Lashing the dinghy to the side for a few tenths because the sea state is such that you are only making 5.5 knots is counter indicated by the very sea state you are trying to get through. Again, ask the charter company, and empty a berth for the skipper.

Now if this is a friends boat - absolutely ask the soon to be former friend if it's okay.

As a backup when the engine dies and you have no wind - think about it - that outboard probably has 4 - 5 gallons of fuel at most, good for 4 to 5 hours of pushing the boat at 3 knots in flat water. Maximum range is easy to calculate - in flat water. Don't even try to tow a 45 footer with a 10 foot dinghy and a 9.9 (standard charter dinghy/ob). The dinghy will saw side to side and you'll get 2 knots of SOG to your destination.

Use the sails if you want to get there faster. It's what they are for.

Re: Back-up motors

Ambitious,

Don't take the tone of the above posts too harshly -- they mean well.

The Dufour's got a diesel engine that should be more than sufficient to serve as a stand alone propulsion source.

While Chuckle's comments are a bit sharp, their underlying points are worth noting. With respect, I seem to think that you may be a tad bit inexperienced as far as bigger sailboats go. Since you've got almost a year to prep for the trip, I'd recommend you spend a fair amount of time boning up on the details. Take a stroll through the sailing section of your local bookstore and look for a boating title that includes the terms "cruising." You'll likely find the money well spent.

Hope you have a good time on the charter.

Re: Back-up motors

Sorry, didn't mean to be sharp - more tongue in cheek.

Internet doesn't show that.

No worries, Chuck I was just a little concerned that since this was his first post, Ambitious may not know you as the cantankerous but generous guy you really are (who, BTW, has finally realized the wisdom and joy of maintaining a single hull instead of two... )

Re: Back-up motors

So if a secondary motor is a loser should I consider investing in a spinnaker to take advantage of wind directions that the jib and mainsail can't?

Re: Back-up motors

btw this is not a charter, we've had the boat in the Chesapeake for about 10 years but use it sparingly, it is getting driven down to Florida in the spring, going out to sea for a few weeks and then most likely being put up for sale when it returns to port in Florida.

Re: Back-up motors

If you are talking buying a sail then obviously it's not a charter.

Look at a asymmetrical or a code 0 instead of a spin - much easier to handle, especially as a furler.

Re: Back-up motors

Ambitious:
Based on your original post and some of the responses, I think we need some clarification here before continuing. Do you own this boat already or are you planning to charter it? If you own it already, where is your home port?

Re: Back-up motors

We own the boat, its a 1998 Dufour 45 classic, and we keep it in Deale, MD, but it is getting driven by tractor trailer down to Florida for the trip.
