Hi! Total disclosure, I am not a windsurfer and know absolutely nothing about the sport. What I am is a rower I'm here because I recently bought a rather rare product which can mount to SUPs and windsurf boards in order to row them.



Today I bought this gem of a board from craigslist. I knew going into it the board was pretty banged up so I only paid $75 for the thing. It's the perfect length and dimensions for my mount so I thought I'd attempt to repair it throughout the winter. I am wondering if there is any advice/tutorials you guys would suggest looking at prior to starting this project. I'm not sure what material "ETA" stands for. All I know about the board right now is that it is a Rainbow Allround Race board and apparently pretty old. I am not sure if the board is so far gone it's not worth repairing other than slapping on some duct tape and caulk, or if I it's within my means to bring the thing back to life for years to come. Any comments are appreciated!

You'd spend less money getting a better board than trying to fix that thing which should have been put out of its misery long ago, the seller was lucky.
That is definitely a case of diminishing returns. I'd bet you could find a much better board w/o spending anymore than you already have that needs no repair other than cosmetic.
It looks like it has too much rocker (curvature of the hull) for your use anyway, it would be very slow.
Look for something flatter with just a little kick in the nose. I used to row quite often.
Sorry.

A long standup paddle board (flat water racing type) would also work, but it would be hard to find one for $75, they haven't been around long enough.

Might be a good idea to reveal your location, someone may be able to help you out with a lot better option than that POS.

I've SUPed on one of the big boards in that pic, worked well. Windsurfer One Design.

No apologies needed! The seller definitely got lucky. My reasons for buying the board were pretty simple. I live in Minnesota (US) and you generally do not see used, cheap long boards up for sale very often. The rig works best on boards 12 feet or longer. When I went to check out the board and saw how ****ty it was, I thought to myself that $50 wasn't that big of a deal to at least have something in my garage I can go out on this Spring in the event another one does not pop up for sale before then. Now I am faced with my original plan to duct tape and caulk the thing so it will last for 1 season, or spend a little bit more to fill it with something proper.

Ideally, as soon as I have the money I will buy one of those fancy shmancy inflatable race SUPs. The rig fits in my trunk so with an inflatable board I'd have quite the mobile package for camping and other trips.

Repairwise here is most info you need...

I find it interesting that it seems to be designed by John Hall who designed and built windsurfers in Sydney.

Ok whats your budget for fixing it ?

Where are you going to row? If it's on a flat lake or river, a good old fashioned Wally (original Windsurfer board) might work better than that banana shape thing?
