Best rough water hull you know.

( killed a nice thread aparently..)

 

Don't worry, it's a slow thread with a good topic.

 

Take a look at this boat

VSV Sharp and pointy.

The owners are farsighted people. They use a traction kite as auxiliary power. http://www.kiteship.com/

Take a look at the Motor Boat magazine article (July 2007, page 89). Cutting Edge :"Why bash over the waves when you could slice through them ?... "
Although you need to go to 70 ft to benefit from a wave slicing hull like this...

 

Simple, just some vertical thinking required - a submarine. Go deep to 400 ft and put on the movie!!!

 

I will concur with Madmat re definition of "rough". It would be generous of designers to include "@ given seastates" in their calculations, hopefully over a wide range to show the comfort/economy zone of their particular craft. As for weight, I will take a heavy boat over a light one if the going is rough. Call it sluggish if you will, but the weight slows down the reaction time nicely. Now if I can just find a design that will cruise at 20knots and be just as smooth at 8, and as long as I'm dreaming, not roll in the trough...

 

light boats dont bob like heavy ones do , the 31 jc wieghing in at 11.000 lb is also hard chine and dont roll in the trough, ,the light boat bobs like a cork in a bucket,,you shake the bucket full of water and the cork ,floats and some part of it is still dry ,,you put a heavy piece of wood in the same bucket and do the same ,the heavy piece bobs below the surface,add some technology and design and you get a 31 jc hull ,,you can make it a pleasere boat or a work boat,,,,for the life of me ,I cant believe the designers on this site have not recognized this boat,,,,they dont advertise ,,because word of mouth is more powerfull ,,I have seen the company go frome a one a month boat yard to haveing at least 2 major yards ,,one in new hampshier and one in fla ,,the boat also has other advantages,being built of airex ,which is lighter and stronger than glass,,and also it floats ,,,,so even if your boat is swampt ,,your not going down,,,,earlier on I made a miss calculation on fuel consumption ,, I rode hurricane juan out on one of these ,,and many tropical depresions,,and was able to outrun 6 other hurricanes on this boat,,,,,,but I still cant believe that the desingers here have refused to look at the positives of these boats,,,,as a commercial fisherman in the gulf of mexico ,,I made at least,,,,,,,40 fishing trips a year.,,,year round ,in all weather ,you can lead a horse to water ,but you cant make him drink ,,,,,,,,longliner

 

yes but the heavy hull requires a much larger engine to push it along which costs more!! get a catamaran and see the light

I thought it was a ROUGH water hull - Cats excluded due to the word ROUGH.

 

Longliner, The way I read it was: You can lead a horse to water, but you cant make him ski... Northerncat, I cant see the light for all the darn spray!

 

Cats are not always unsuited for rough conditions. http://www.alnmaritec.co.uk/category_boats_07.html would not be in business if the vessels they build were not up to the mark.

The facts speak for themselves.

pericles,,why are all the photos in slick calm sea?

 

Longliner,

So you can see the boats, not the spray

Here are the MCA catagories explained. http://www.powerboat-training.co.uk/articles/articles-RIB charter.htm

Weather in the North Sea can be atrocious, http://en.wikipedia.org/wiki/North_Sea

yet the oil rig and wind farm service boats are out in all seasons. In the end, the boats are usually tougher than the crews.

still dont see cats in any rough weather ....just some pics of pretty places,and a bunch of words.,,,,,,,,just dont see it ,,when a boats wieght is divided and spread out over 2 hulls,,,,with no draft to speak of ,going rough,they tip over you know,never to have a chance to correct ,,not that all monos are 100 %gaurnteed to correct,but for my money and choises ,and takeing my chances,will be a mono,,,,,,preferably a fixed keel sailboat,,,,,work boats are so,,,,,how you say,,,,,alotaworktodoallthetime,,longliner
