Well we had flares - lifejackets - spare fuel - first aid kit - gps - even an anchor.

The most important thing was - it was a NICE day!!!

Remember with the 15hp we can cruise at about 15 - 20mph so didn't take too long. Didn't even use all of our 3 gallon main tank....

I'll grant you I have just checked and most 4strokes are weighing the same in the 4-9.9 HP range regardless of power, however typically the 6HP version is 300 more expensive than the 4HP! Thats quite a lot of fuel...

...given the intended application (as a tender - and for pottering about) - I'm not convinced that the original questioner needs more power (although that depends on his feelings about going fast). Many, many yachtsmen are perfectly happy with 4HP and less on tenders (often quite heavily laden) for the relatively short journey to shore and back. Afterall he is managing with a 2.2 HP on a similar sized boat just now...

Hi
We have been using an ax2 with a 2.3 honda on the back.
Although very practical and light, wet backside and a very noisey engine has forced us into something a bit bigger. I am picking up a yam 4.hp on a Zodiac 2.6s with a new roll floor system Friday. That combo should give us plenty of go for just under a grand.

Hmm. Not much on pros and cons of solid floor/keel (RIB) vs inflatable (SIB). Does that mean that most people don't see the point of a RIB that small, I mean no benefit over inflatable keel boats?

If that was the case, assuming a high pressure inflated keel, what about the choice between sectional ply or aluminium floor vs and inflatable floor? My thoughts are that I'd prefer the sectional floor. Easier to adapt if for example I want to add lashing eyes or something, and one less thing to pump up and worry about puncturing.

Thanks for the differing comments on engines. The ability to zip along is appealing, but I guess I'll need to decide how much I'm prepared to pay for that. It would open up some more uses from the boat.

I wasn't seriously intending to use the 2.2 except for trials - at the very least I'd want F-N controls, and a 4hp with F-N-R is probably the sensible minimum.

I use a flatacraft force 3 RIB with a 3.5hp tohatsu as a tender,the 3.5 is light enough to get on board easily and the flatacraft tows well due to the heavier bottom but is a bit more of a struggle to push around full of kit with the outboard on(really tough with a 15 on the back).
The flatacraft will plane one up but any more weight and it is displacement speed only with the 3.5.
The flatacraft will convert to a safe sailing dinghy also.
The RIB is alot tougher and takes the knocks much better then a soft floor and will tow safer due to weight then an air floor inflatable(which I think could flip in high winds).
I have however had the RIB try to overtake me in a large following sea.

I think that depends a little. If you do decide to put a big(ger) engine on it and use at speed then a RIB will probably be more comfortable (although if it is heavier may not go as fast with the same engine).

If it is for "pottering" and as a tender - I'm not sure it would be worth what I imagine is a fairly significant extra cost?

Generally people are inclined towards SIBs (with or without hard floors) because they are "easily" folded away and stored when not in use - that doesn't seem to be a concern/priority to you.

GandyGoose, will you be landing on exposed beaches possibly subject to a bit of breaking water and will you need to haul the boat up the beach? If so, light is best because you'll need to escape the boat, grab it and get it out of the break pronto or the next wave is likely to fill it up. Inflatables and small ribs lie very close to the water, typically just a tube diameter above the surface. Also, a wee boat can become surprisingly heavy after carrying it 50mtrs. Wheels might be good.

Cheers once again. The point about weight is well taken, although anything I'm looking at will probably be lighter than our 10' fibreglass dinghy, and easier to pull on/off the trolley as well.

Sticking with the "very small RIB" theme, there's the Zodiac Zoom 310 that I've seen in the flesh, the Flatacraft, and I see Valiant make a 3.00 basic RIB as well. Are there any other makes I should be looking at?

I think the flatacraft option would have to be second hand!
