Trailer dimensions

I need a bit of help as i cannot seem to find the measerment I need online.

I have just bought a hobie 17, its old and a bit tired but for the beach in front of the house will be prefect.
Anyway it has to live on our beach ( which is more of a cliff than a beach) so I am building a trailer/dolly thing that will allow me to store the boat and not damage the rudders on the trip up/down.

But I need some measurements that I cant seem to find..

1) Hull to hull minimum inside width (the smallest measure between the hulls)
2) hull to hull centre width ( the middle of the hulls at the deepest point/centre/ where it will sit on the rollers)
3) Dolphin striker depth ( how far it comes down in relation to the bottom of the hulls... so the clearance between the dolphin striker and the ground if the boat is sitting on the beach)

Any help would be most appreciated.. I am starting to build this tonight.

Thanks
Dylan

If you have the H17 already the measurements are right in front of you. Just be sure to measure twice and cut once
