rib build

r mcdonald · 26 May 2010, 15:03

Thankyou everyone on RIBNET for the information you gave me over the last couple of years.
I have launched my 7.5m rib that I designed myself using Greg Carlson Design software(freeware). The rib has a tohatsu 90tldi on the back and she did 28kts WOT. I am very happy so far.I still have to finish the cabin,roof and another 90 tldi will be arriving soon so I will have a twin setup. The collar was bought from Henshaws and they were very helpful with the questions I had (thanks Chris and your staff).
You can see some of the stages of build at

Wow! I have exactly the same project planned ahead. But mine´s going to be 4.2m. I like the way you have constructed hull panels on a flat table. I think I´m going to borrow that idea.

Two thumbs up!

Wow!!!!!!!!!!
Very nice to see.
This must cost lots and lots of time.
Is this all a hobby, in other words al the work done in your spare time?
Good luck finishing her, and lots of fun!!!!!!

Wow, how long did it take (hours), to get to that stage?
You must have previous experience with fiberglass to even attempt a project of this scale?

It looks really good.
Please keep the posts coming.

To answer a few questions.
It is a hobby, I made it in my spare time.As for the hours I not to sure.Some days I would go over to the shed and stare at the Rib for an hour or so and not do a thing, then come home.I would also lay in bed at night thinking what I would do the next on the Rib.I did alot of reading of books and on the web. This site and the people on it are fantasic.
The collar arrived October 2008 so it has taken about two and a half years. I had some help from a shipwright for about 45 hours during the 2 1/2 years, so It was not all my labor.
I have had some previous fibreglass work ,I but not a lot.The only difference between a big RIb and small Rib you use more glass, resin and more sanding.I owned a SR5.4 about 20 years ago,I should never had sold it.I had so much fun in it.
I have enjoyed designing and building the RIb.There was always the risk after all the time building it. It would be a complete failure, I always thought that if it was easy and no risk there would be no satisfaction.
The first time I drove the Rib out of the boat ramp harbour,the rib felt good even just ilding into some small 2 foot chop.After increasing the revs 1000 at a time making sure it tracked straight and turned port and starboard smoothly and safely, I had it going as fast as the 90 would take it turning port and starboard.Nobody could wipe the smile of my face for quite a while.
If you include all your time to build the Rib it would be cheaper to buy one complete. The materails cost me about 1/3 the cost of a complete hull. I have a saying "why buy it when you can build it".I love to tinker.

A beast with it's teeth knocked out. Let Nuge bring that soppy 90 home in his hand luggage and shove a 300 on there.
