rib racing, covered bow

Anyone from the old rib racing days, find much improvement in speed by covering the bow? Ive heard a few people mention it, but trying to figure out a way of proving it soon. My rub rail isnt big enough to hook anything onto, and any deck or covered bow id fit, would obviously add weight

The canvas tops used to add speed considerably. On 7m race RIB we gained about 6mph

There were some French guys in a rib with a covered front when we went round Britain, it does make a difference, the wind come over the bow and creates a vortex.
There are two main ways of doing it, you can use an acrylic hood cloth or if you want it more permanent you can do a tech layup in GRP, obvious problems with mooring lines etc but worth doing if you want to be more competitive

I dont have exact details. It appears with covered lightweight bow most people gained 5ish mph. One person reported increased bow steer so used bow lifting props but nevwr settled the boat with cover. None of my data. Just what others told me

Have you got the engine height spot on? have you moved all the heavy stuff right to the back? Have you tried a few different props? I think all of these would offer at least as much if not more improvement in speed.

I think the regional systems less important when the hull is not built for high speeds
