Avon 5.4 SR Navy Spec V's Standard Rescue

[ribsta]

Apart from the obvious visual differences, does anyone know the differences between the 2 specs?
Reason I ask is, my mate has a standard rescue SR (white hull version) and the ride is a lot less stable than my Navy spec. Calm or choppy the Navy one seems to handle the sea with much more ease.

If it's original white grp then it could be an avon adventurer prototype, either way it will be lighter than yours.

What colour are your mates tubes?

Trim and engine set up will also make a difference too

[ribsta]

Tubes are grey. The hull form inside and out are identical and both boats are from mid 90's. My Navy boat has a 1997 Yammie 85 and the standard boat has a 75 Etec. I didn't think that was too different. Both have identical 'A' Frames.

Is his flooding hull blocked up either on purpose or by some rubbish...

[ribsta]

Nope. Both the hulls are plugged and no water trapped.
I get the feeling this may be a phenomena.
I checked out the weights and I think the navy spec is 30kgs heavier. Must be in the tubes and perhaps heavier layup.
The reason for my questions are that my mate needs his tubes doing up, but prefers the ride of my navy spec boat and therefore trying to decide to sell and look for a navy one.
I must say the Macmillan rib is looking fantastic.

prresuming the seats are in the same position then its engine weight affecting the boats balance. Im always banging on about it but you have a 26 kilo difference in the weight of the outboards. swap the motors over and prove me wrong

I would also check the offset on the outboard. The navy spec ones have had a lot of research done to get the right offset which they say makes a big difference.

Cheers guys. I guess with that extra weight hanging on the back and with less weight in the RIB it will be different. If the tubes are beefed up by adding 30kgs of rubber to the standard SR, might make a difference, but the Yammie engine on the Navy spec will still play a part in providing a better balanced ride I guess.

These are the 2 boats in question....
