Ok, I have a canal at my cottage in Maine, the width is 84 inches, and is lined with a very thin carpet...I know a Donzi 18 2 + 3 is suppose to be 84 inches wide, what would that boat measure with the black rubber moulding and aluminum housing of the rub rail removed measure?

I have a line on a couple project boats, maybe if I get one, thin it up a bit.

Let me know, crazy perhaps and purists will cringe, but thinking about building a serious high speed Donzi, once my car projects are done. Maybe even put in 68 Corvette taillights....haha

Regards, Tim

I just checked, and at the widest spot(at the throttle/shifter)I got 83" from outside the rails. It was even a hair less than that, but not 82 1/2".

Keep in mind that the Donzi 18 & 16 does not have any rubber insert that sticks out from the rubrail molding; at least on most of the earlier boats.
The original aluminum rubrail molding itself is a very flat slightly semi-rounded alumium extrusion.
You might be able to put a slightly lower profile strip of totally flat Aluminum , or Stainless Steel trim metal stock back in place of the original aluminum rubrail extrusion ?

That's a very tight canal you have there.
Make sure there are no slightly tighter spots anywhere in your way along it's entire canal length as it's going to be a very tight squeese .
Lots of project Donzi 18 hulls pop-up from time to time here, and on ebay, & craigslist.

if I do this, I likely would make a custom rub rain as needed....I am very familiar with the canal, no other tight spots

years ago, our first boat, my father got for a great deal and as my grandfather had a body shop for over 50 years, they re did the full made it an inch or two smaller overall so it would fit

with a classic 18 having a beam of 84, I likely will be fine just by thinning up the rub rail with someone custom

thanks for posting!

a 16 will fit, an 18 will be pushing it for sure

let me try to find a pic, basically it is a cement wall on other side, about 30 feet long and the road passes over it

A newer 16 is two inches narrower than an 18 A good list might help narrow the beam like two people on one side

measured the canal this weekend, it is 83 1/4 but my 16 which is suppose to be 83 goes right through with an inch to spare...if the 18s, especially earlier one with the thinner type rub rail measures 83, I should be fine, without modding it...

How do you keep boat sides from scraping sides of concrete wall? Sounds tricky.:boggled:

Sounds like a two person job at the least?

some of the people on the lake lined each wall with indoor outdoor carpet so boats that are a tight squeeze go right through, we have to lift the drive up, I walk it through the tunnel

what year is your boat? are all the classic 18 hulls the same width? I know that have various mouldings, the early have the thinner alum moulding, later combo of alum and rubber which are likely thicker.

if I can find an early boat with alum mouldings, if it were real tight, I could take off the mouldings and fabricate a nice thin moulding from alum stock...

I appreciate the info....likely can get an 18 to fit
