A good source of info?

Greetings, new to the very idea of getting a RIB and finding it frustrating to find good information. An example, I saw a reference to a "D-Tube" and did not know what that was. I have googled long and hard have yet to find an answer. Now I figured it was a D shaped tube, but could not find out the why of such a thing, better, worse, what application, whatever. Also trying to find which hulls are deep V and which are shallow or modified V, well, that seems to be a closely held secret, too!
So, wondering if anyone could direct me to an "all about RIBs for dummies" or something similar I would be most appreciative. I need to know a bit before even asking questions here!
I'm not a complete boating newbie, I've had a sailboat and spent lots of days on ski boats, but I've been out of boating for decades, about to retire, and ready for something new.

One persons deep V is another's medium V. I think the logic behind d shaped tubes is to increase the internal beam but the fact they aren't more widespread suggests for most applications they may be a compromise.

Welcome to RIBnet. A friend of mine was in Nashville last week and saw a big sign that she said reminded her of me.
It said "RIB Festival"...

...turns out it was the BBQ variety


You might consider further reading and then a good old dig around on here.

deep V typically 24 degree deadrise medium V 15 degree deadrise which usually end in a planing pad at the stern manufacturers will differ on angle
D tube reference the only one i know of is the foam filled sponson on commercial boats such as delta.

Maybe "D" fendering was relating to the "D" shaped rubbing strakes that are sommon on some ribs?

D-tubes are rare for recreational boats. They're very expensive to manufacture.

Why do you need a deep V in Nashville?

If you're on Lake Cumberland, you don't need a big offshore machine... A flatter bottom boat will plane easier and be more stable at higher speeds.

You could try the "Complete RIB Manual" by Dag Pike.

Hey cool, lots of replies! Richard, I'll be using this boat in the G of M, but either way do not want a deep V hull, as I do not tend to go fast over waves anyway. I'll check out that book.
thanks everyone
Bill
