[MHml] horsepower & sleds

Towing is easier than pushing - but you need weight in the RIB or it will slew all over the place. An easy way is just to flood the floor , this is necessary when slow manovering and starting off, once up to speed drop the flooded water. Avon Seariders are excellent in this situation as their hull is designed to flood and empty
 
for the engine on afterburner:
what about an internal 'trunk' ie a box that lifts out inside one hull that you can drop the outboard into (venting it outside obviosuly).  the prop will always be in the water.
 
when you get to destination - lift out engine - drop in 'box' to seal hull and reestablish hull shape- minimal weight if built in foam/carbon
 
we used to have this arrangment on Mollymawk and it worked really well - until the rules changed which meant we had to change the set-up. 
How much HP do you need??
10hp pushed Mollymawk at 6-7knots when in it's well and 5-6 knots when mounted aft on a conventional o/boatrd bracket as the engine was lifted in and out of the water due to pitching 
5Hp pushes Charleston at 8knots, -but she is more an overgrown, steroid fed, beachcat
 
20 or 25hp in an internal set up should allow Afterburner to move easily at 8-10 knots ??
