Our Tornado 9,5 has done over 400 hours this year
Allthoug its a big an heavy boat our back, neck and knees
is taking plenty of beating even in the calm Oslofjord.
Have tried several ribs wiyhout them but since were using
so many hours in the boat there really is no alternative.
Its allways an option to buy one and then you can change it over to
your next boat.
I strongly recomend Ullmans, Try one in some rough seas
and i think you will be convinced.
