the 50 vision has an avs of 121, what does avs tell us?
As far as i know, it tells us how far a roll can go before the boat is likely to immediately self right and how stable it is upside down, but bear in mind it will take a far greater wave to roll a 40 foot boat with an avs of 121 than a 50ft boat of 121 avs. Now a wave with enough energy to roll a 50 ft boat will roll the boat regardless of its avs, whther it is 120 or 150 both boats will roll (given roughly same weight) the boat with the 150 avs will most likely self right quicker as it is less stable turned turtle and will require a smaller wave to self right. (please correct me if i am wrong in any of this).
This i why i say a 35 ft boat with higher avs is not as good as a 50ft boat with lower avs ie why you are better to get a bigger boat than a smaller more seaworthy
boat, you have far less chance of being rolled in the first place. is it not better to get a bigger boat that is far less likely to be rolled in the first place, than a smaller boat but with better numbers but will be rolled by a far smaller breaking wave, bear in mind it only takes 12 foot of breaking wave beam on to roll a 40 foot boat.(mono) if a cat you can double that then add a bit. One of the findings from the fastnet disaster was that not one boat over 45 feet in length was lost
, and that neither make nor seaworthyness nor skipper
skill made very little difference, size was what mattered....
one of the reasons i wanted a boat of 45 foot or over.if in doubt of what i say please correct me or check the physics involved as i spent a few months reading the physics on just this subject. as for those advovating older designs, he beam of the boat was what counted, sure a beamier boat may roll more, but the breaking wave has to approach the beam size in order to roll the boat , so a narrower boat will roll in a smaller breaking wave, it may have a more seakindlier motion but when it comes right down to being rolled it , will roll with a smaller breaking wave than a beamier boat.
Id rather be tossed about a bit more and have more resitance to being rolled. As for bavaria
, yeah they aint the best, but hey there are over 50,000 of them on the planet, and ive yet to find one sory of one sunk by a storm. there was a problem with the match series with bad keels/keel support and these were light weight racers rushed into production.
boatman 61 i worked in the north sea of scotland
in a 35 foot fishing
boat for 2 years, granted it would certainly not be a place id take a yacht willingly, but ive seen some very large seas and skippers with a large catch thats going to go rotten wait for no storm. I maybe be new to yachting as things go, but im certainly not new to the sea,
