Hi Paul. Where have you been, I have been trying to get in touch with you about putting a bow section on one of our boats!
I aggree, that a "Full Tube" is more suited to ribs up to 10 metre, but anything after that it all becomes a bit of a problem in "interesting seas"
I was up in Ireland and Scotland at the weekend and there is no question, the Storm Force 11.5 is one hell of a boat and just punches through anything that is thrown irs was. On the way back from Port Patrick I was on ahard noes Scorpion in difficult head seas and again it did its job where as a full tube would have stuffed. At the end of the day it is down to the sea conditions as to which type is best. My version of big seas is proberbly very different to most peoples.
I will give you a call about putting my tube back on.
