I ended up with an old surfboard after a mate moved away.
It's a Darryl Bulger 'Trent' 6'5" x 19 1/2"
I had the idea to turn it into a kiteboard by adding another layer of fibreglass, to add strength, and footstraps couse i'm a noob.
The board shows signs of stress, fracture lines in the glass on the underside.
It had quite a dinged up deck, i've filled and sanded it back to a decent flat surface. Next is the Under side.
The fins are cut down quite short, thats how i got it.
I need to know if i should cut them off and fit new fins, Shape them better, or leave them as is.
If new fins, what kind? 2" kiteboard fins?
I also what advise on placement of the straps.
How many straps?
I was going to put 2 straps on. both on an angle accross the centre line, as on a twin tip, and also have a large area padded so i can move my feet if i progress that far.
I have footstraps, and an idea of where to get the inserts (someone here has an excess) and i have enough 100gsm glass on its way, to do both sides.

so this is my plan:
1. fill and sand underside
2. decide what to do about the fins. HELP!!!!
3. Locate and fit inserts for footstraps. HELP!!!!
4. lay new glass
