I am designing a runabout and wanted to know the reinforcement requirements for a boat of 4m x 1.6m. Can anyone suggest any thread or recommend any classification rules which mention the frame spacing? This is for a fiberglass boat construction.
 
The requirement is very simple: the boat should not suffer any damage when dropped into water from a height of 2-2.5 meters.

The norm is ISO 12215-5:2008 (Annex B)
 
Thank you. Let me got through ISO 12215-5:2008.
 
Thank you TANSL, but how can i convert the language to english?
 
Since I do not have any ISO standards, can anyone suggest DNV, ABS, RINA or IRS class rules for small boat scantlings. Based on IRS class, the bottom plate thickness is calculated as 9mm. Is this very conservative? Can you suggest the transverse frame spacing usually used in small boats?

On another note, I have designed the hull in Delftship and imported the design to rhino. But in rhino I only get the edges. Can anyone show me how to create the hull surface. I wanted to create sectional views from rhino for issuing construction drawings.

As far as I know, by now nearly all class rules are demanding the use of ISO 12215 for scantling of small pleasure boats, so I am afraid you will have to get a copy of ISO standards.
And as far as I know (again) this is the cheapest place where you can buy a copy of these standards: http://www.evs.ee/shop
