The Next Step | Sail and Power | Exposing Secrets of the Dashew FPB and Sailing Designs 

Our pleasure, we are happy to share what we have learned.

We're glad you liked it. Thank you for your continued support!

Hi guys I am looking ICTI buying Intermezzo in Anacortes

At 80 you are dreamer and that is so laudable just need to become a believer and the seven seas will be yours. God bless you too !

You could build a remote controlled model boat replica.

Howdy Karl: We have addressed the question of licensing before so we won't repeat.ourselves. As to adding to the video content, we enjoy doing this, but is only since we "retired" that we have had the time.

It really is!

Glad you enjoyed it!

We have a lot of footage from old videos we made through the years. Do you think people would be interested in seeing more of it?

@@DashewOffshore Most definitely

Glad you enjoyed it

Design issue first. To plane requires a hull surface that is relatively flat, light weight, a large sail plan, and the stability to carry the sail. The power to weight ratio has to be very favorable as well. In a cruising yacht this means lots of beam, attention to weight management and payload, along with a deep keel, canting preferably, which then gets you into dagger boards to offset leeway. We are talking expensive, fussy to sail, and uncomfortable end results. Take a look at the Open 60s for a good example. Now some hydrodynamics...Sailing drag off the wind is made up from wave drag which is proportional to the square of boat speed, and wetted surface drag which goes up in direct relation to boat speed (linear). The. power which can be developed from the wind is a square function of wind speed. Now it gets interesting. The relationship between wave drag and wetted surface drag is controlled by the displacement length ratio. Higher DLRs have mainly wave drag at high speed. As the DLR drops wave drag becomes a smaller percentage. of the total. DLR is a function of the weight. of the vessel. and its water line length cubed. So a modest increase in LWL will have a huge impact on the wave drag/wetted surface drag relationship. Take a long, slender, hull form, with a low DLR and combine it with a moderate sized rig with efficient design, and you end up with a package that can create force from its apparent wind more quickly than the drag builds up. Our low DLR design has essentially linear drag increase as boat speed goes up. But the force in the wind goes up with the square of the wind velocity. Now throw in the change in apparent wind direction forward as the boat speed increases and the apparent wind speed both climbs and interacts with the rig at angles which enhance power. An ice boat is an extreme example of this, being able to clock five or more times wind speed. High performance multi hulls can get into the twice or more wind speed range. In the context of a modern, go anywhere, tough cruising yacht with modest draft, and normal systems, you can have your own apparent wind machine by simply lengthening the waterline. Take a look at the videos of Beowulf on this You-Tube channel to see what I am talking about. About the business of yacht design, it is not easy, and if you are good enough to make it in this game your talents and hard work would probably be better aimed at another field of endeavor. But some times you have no choice. If this your situation, then my advice is to spend a five or ten years actually out there cruising. On larger yachts as crew, and on your own vessel as well. This experience will provide you with a real world foundation against which you can make the many trade off decisions that are a part of yacht design and construction. As to reading material, you might start with four of our books, available now as free PDF downloads on SetSail.com. Good Luck!

DashewOffshore What a fantastic and informative response Steve. Thanks!

Hello Michael: Not sure of her status but if you contact Sue Grant at Berthons International she will know.

We have taken solar charging to the practical limit in the context of maximum reliability for our type of cruising. Cochise has 16 of the most efficient commercial solar panels, producing 345 watts each, and sufficient power to typically run all systems, including air conditioning at anchor. But solar for propulsion is a different s story. Too many tradeoffs for our taste. As to batteries, we prefer batteries which do not require micro processors for charging control. That leaves Lion batteries out. Maybe some day in the future this will change.

There is only one iceberg and you will have competition if the owner ever decides to sell.

@@gendaminoru3195 She is for sale right now ...

@@gendaminoru3195 www.yachtworld.es/barcos/2014/Circa-Marine-FPB-97-3617912/

For Iceberg you will need 6.5 million min. offer plus maintenance good luck.

@@Ozmy in this economy me thinks more like 5.5 or less, but if he doesn't have to sell then he could stick to 7.0 if he wanted. Curious about your remark on maintenance. Have yo checked it out? I will prolly rather spend money on an airplane anyway since it helps earn money. Yachts are holes in the water your pour money into.

Morning John: You understand correctly. We tried to come up with a program that would insure that the FPBs would be built in accordance with our specs. Otherwise, our new customers might not be getting the correct product. It was in our interest to find someone to carry on. However, try as we might, nothing met the goals.

@@DashewOffshore I'm sorry to hear that, but best wishes on your retirement, and fair winds.

We are glad you like them! We enjoy sharing the information.

Thank you Mark, we are glad to be able to continue sharing some of what we have learned over the years.

For Beowulf motoring that sounds about right.

she is for sale and plenty of detailed interior pictures on yachtworld ....

There is also a walkthrough available on RU-vid - ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-MNTbx-T6s8s.html

Are you kidding me? The US has more untapped oil in Alaska than the Saudis have ever had. It is not counted as available because of legislation which has deemed the land off limits. Once our gov gets out of the control game, we will have a couple hundred years worth of oil just in Alaska. That isn't counting the unavailable oil we have in the lower States. Where does Australia find people like you. You are an embarrassment with your gullibility.

@@lightning9279 if you go to IndexMundi you will find energy data on all countries. All types of energy not just oil. If you Google:- mundi oil imports by country. You discover how much oil USA imports each day. About 7 million barrels a day. USA shale oil will decline soon, then USA will have to import more oil. If a person spends more than they earn we know what will happen. Mankind is burning 36 billion barrels of oil PA. Only 9 billion barrels is found each year. A short fall 27 billion barrels PA. The situation is not sustainable. Cheers Gray

@graham, 1948. Humphrey Bogart in TREASURE OF THE SIERRA MADRE. At the beginning of the story, the American crew were in Mexico doing what? And they were laid-off because the oil companies did what? . We are in a long-game. A few minutes research will show the source of the marketing term 'fossil fuel', a gimmick fabricated by Rockefeller to give the impression of scarcity. . This particular planet has infinite amounts of oil. And it is constantly creating more. . Next.

Hello Road: There are a lot of variables, but lets say you go from New York to Kinsale, Ireland, and allow 2700 nm for the passage. If you are on Wind Horse, and are patient, waiting for a high to develop and then ride the Gulf Stream and high circulation (-north side), you will average 11 knots, burning 6 .5 gallons of fuel per hour. You will have topped the tanks off at the fishboat fuel dock o maybe paid $2.00 per gallon.So 245 hours at /hour, $13.00, or $6375, Play the weather just right and you could shave 1/3rd.

@@DashewOffshore Amazing !!

Except they are are retired and no longer taking new orders AFAIK.

@@genephipps6421 Not according to this video,talking about their new innovations.

Yes, we are retired. We are trying to pass on a little of what we have learned. The object is to have the consumer demand more. Otherwise, nothing will change in the marine industry..

Hi Roderick: Your comment reminds me of s discussion I had with my Dad in 1975. We had just purchased Intermezzo, a 50' ketch. She had a large cockpit and an even larger dodger covering the cockpit. That dodger was ugly as sin and it was high on my must do list. My idea was a minimal pram hood over the companionway. Much less offensive aesthetically, and almost no drag. When I explained this to my Dad, he took it in, and then a couple of hours later suggested I hold off on the change until we had used the boat a while. "You only see the dodger when you are off the boat. You will enjoy the benefits a lot more of the time." He was right of course. The Matrix deck might be the ultimate expression of my Dad's advice. Yes, it adds windage and we can see the fuel meters react in headwinds. But it also acts as sail area in a good breeze downwind, although overall, it is a net negative in this regard. And you will get no argument from me that a smaller structure would look better. Against all of this we have to weigh the benefits. I can tell you with certainty that the Matrix deck totally transforms the FPB 78 for us. Rather than being just where we stand watch, it has become our prime entertainment area, makes it possible for us and crew, or long term guests to have separate space, is where we exercise, and more often than not is where we set up the office. You will find the same response from the five other owners of the FPBs with Matrix decks.

Hello Beamer: Until 1988 all our aluminum yachts were painted.Although we tried we could not get a client to leave theiryacht bare.Then we decided we decided to try this on our own Sundeer and we have not painted a clients yacht since. There are several posts on this subject on SetSail.com if you are interested. setsail.com/painted-or-bare-aluminum/#more-18163 setsail.com/bare-aluminum-topside-maintenance/ setsail.com/aesthetics-form-does-follow-function/

That industrial look is just great. My concern is about the aluminum and being in it for some time. Is it healthy?
