What would a course teach you that would be different ?
It would show you the joy and ease of close quarter manoeuvring with twins - rule of opposites - different pivot points.

I used a twin engine RIB for Powerboat training and did not find any marketing advantage.

OK, so its not just me scratching my head. One or two engines - Im not sure I can figure out why/how they would be different - within the constraints of a basic PB 1 and 2 course.

I will of course see what happnes myself by using just one, but what would a course teach me that I couldnt figure out myself ?

Until you have had the opportunity to use twins and be shown the correct way to use them it all sounds very tricky. In reality it takes very little time to get the hang of them.

In slow speed manoeuvres use the outside engine in tickover and leave the inside engine in neutral.

Cheers, I plan to spend an afternoon messing about just doing that sort of thing soon in the confines of Poole before I venture much further.

Spend 30 mins doing turns in a confined space and you will be fine.

So for example it is:
Full right lock
Port engine tickover forward
Back to neutral
Full left lock
Starboard engine tickover astern
Back to neutral
And repeat

I would be interested in a short half day course along the lines of;

1. Classroom - learn the differences of one engine vs two engines techniques, manoovering etc. say 1 to 2 hours
2. Practicle - 2 hours, comming alongside, manouveres etc
3. Classroom - recap 1 hour

cost - would be willing on paying up to 125.00

if thats any use for feedback

its a good idea but not sure it would pay commercially to own it. prehaps if you could use on ad hoc basis?

sure if it was coded it could get charter work for support boat duties for some of the yacht race teams?
Hi Howard
Yes that's the one
Seems not something most rib owners would be interested in how to use a twin set up so will pass on the owners offer.
