Iam pretty convinced it is a TRIM box fin, these are not so common, they do appear on EBay. Some shops will have some product.

in Denver :Larsons had the one on the right side of the photo.

True Ames show this one:

True Ames' shop is local for me, and I can say that they've got a stock of some fins with the Trim Box base, because I've seen them on the shelf. If I were you, I'd give them a call to see what models are in stock, and what new fin pricing would be. Quality G10 fins aren't cheap (usually $90-150), but if you're going to keep the board for a while, it would be a good investment. Since boards with Trimbox finboxes are rather rare these days, the used market might prove a bit challenging. Still though, many windsurfers have a quiver of fins from years past, and they may be able to help you out at fire sale prices.

Fanatic began using the Trim box fin system for their Mega and largest Ultra boards in 1992 according to Windsurfing Magazine's March 1992 equipment issue. The March 1993 issue lists a Fantatic Ultra Ram at 10 ft 3", 149 ltrs, 25.3" wide & 24.8 lbs. The March 1994 issue lists a Fanatic Pure Ram 310 at 10 ft 3", 145 ltrs, 25.8" wide & 25.74 lbs (also available as an Ultra Ram). The March 1995 issue shows 26 lbs as the weight. The Fanatic Ultra Ram wasn't mentioned before 1993 or after 1995.

The Ultra Ram was not intended for beginners. Learning to windsurf on an Ultra Ram will take more determination and stubbornness than 99% of the population has...even with lessons. If you can, start with lessons on a modern, really wide, beginner board, something about 33" wide or wider. After you know how to windsurf on a wide board, the Ultra Ram will still be a big challenge, but it will also be good enough to progress on.

Tell us where you are so we can help you find some lessons.

Welcome to the sport of windsurfing. I hope you are as hooked by the continual combination of challenge, frustration & satisfaction as I am in my 31st season.

I will venture to guess a new fin will cost considerably more than he paid for the board itself.

yes, often i am disappointed how much a fin costs as opposed to the old boards
however, on e-bay sometimes they are around $30 and do NOT cost much to ship

I didn't catch where the OP lives. If it is in the gorge then you want to hit the CGWA or Windance swap meets. CGWA has a bucket (at least they did last year) of old fins. So the price would be a lot more reasonable than a new fin for a fairly old board....

As much as I hate to disagree with the Chief Tester and Grand Poobah at the Colorado Windsurf Fin Test Center, and assuming that the board has a working centerboard, I would put just about any fin in it, 30 cm or better, that I could find really cheap, like 10 to 30 dollars. Most of your power will come from the centerboard, but you need something in that finbox. A couple of other things to know: there are 4 brass inserts in that fin base, but you really only need one good one. Also, many bases need to be either sanded down or, more likely, have plastic tape added to the sides to fit correctly (snugly) in the fin box. If a screw comes with your fin, it will most likely be too short. It's a Murphy's law thing.

I agree with dennis_c. In displacement mode, 20 or 25 cm will do.

umm I did not realize that this board had a centerboard. Does it retract fully into the bottom ?

It does change my suggested fin size, and in the OP favor a much smaller fin. A few listed on ebay for 30$$ ish .

We at the 'Center' are busy packing our test equipment for spring in Hatteras.

I dont recall any trim box fins or boards available. Will search on arrival.

Your post is funny beyond words.

Very Happy Very Happy Very Happy
