do roundnose hulls need reinforcing like sn's doo??

i was thinking of getting a squarenose superjet and was informed that they should be reinforced especially around the engine bay area. What i was wondering was if roundnoses were made out of the same weak material or if they needed to be reinforced.

Its not so much as weak material, its just the thickness. Why would you need to reinforce it if you live in Minnesota?

two layers of 17oz biaxial right around the sn pole mount enough for flatwater?

I would fill the holes, reinforce with at least 2 layers, then redrill the holes. That should be enough unless you really yank on the pole while riding.

I put an xmetal pole on my sn without reinforcing at all at first, but you could watch the entire mounting area flex and move while just raising and lowering the pole. I have 2 layers now and it is pretty solid, but I would do more if I rode harder.

squares need lots more work than rn. the only place you may develop cracks on the rn hull in flatwater is on the lowerdeck. for surf they should both be reinforced on the nose, crown, engine compartment, tray, and if you refoam, gunwhales.
 
What about the tray area? I have seen some warped superjet trays too.

I was looking at a 91 SJ but think it might weigh as much as my 750 by the time I was done reinforcing.

I flipped the SN hull upside down and filled the voids on each side of the handlepole mount with thickened epoxy. I put a few layers of glass over it all the way acroos the handle pole mount before the thickened epoxy setup. It was alot more solid than stock.
