yes more than enough i have a similar set up 2.3mtr tender and 2.5hp outboard, it is plenty for what you want it to do

even a pair of oars will get you to shore and back

Yes, provided you don't fill the boat up with stores(booze)!!
I've got a 2.3 on the river and can make decent progress upstream - Er, not today though!!!!

Dinghy outboard size

Hi guys merry xmas we have a inflatable dingy not rib, is a 2.5 hp strong enough for 2 people and small dog to get from mooring to shore thanks for any reply.r

You dont give any details of the dinghy.

3 Hp was the maximum size recommended for the smallest round tailed, floppy bottom Avons ( Avon 7 and Redstart) Capacity 550 lbs or 3 persons

The solid transom Rovers started off at 5 hp max for the 2.5m version.

But unless you are talking about a significantly larger dinghy 2.5 should be quite adequate

We used to use a Seagull Featherweight, about 1.5hp or less, on an Avon Redstart with up to 3 adults on board

A bigger O/B would only be "needed" if you wanted to demonstrate that you were an ass by whizzing round the anchorage/ moorings annoying people.

I have a 2hp on a 2.4m dink & can transport up to 4 people (without gear) in calm weather. But mostly I prefer oars as it's quieter & lighter than an O/B to lift on/off the dink or pushpit mounting. If carrying more that 2 with oars it is necessary to use them as paddles with a paddler each side near the bow & 2 passengers either side near the transom.

I haven't bothered to use the O/B for 4 seasons now.

I have a 5hp 2-stroke on a 2.4m dink.

It's a bit heavier than ideal, but still manageable, has a built in tank, and a remote tank, and if you are in open water with one person on board, it will plane. GPS says 9.9kts . Extreme Tender in even a small chop at 9kts is a huge amount of fun.

It saved the day last season, approaching the stern of the bigger boat in what was, because of a combination of factors, a very strong current thru East Head. It needed full throttle to get to the bathing platform

95% of the time, a smaller 2.5 or 3.3 would be fine for non-planing duties.

Having used my rubber duck on the Conway where my mooring was near the Cobb & the current exceeds 5kts at half tide, I am surprised you have managed to put yourself in such a dangerous position.

With a little thought it is possible to make way upstream of your destination (use the eddies) so that you can ferry glide down to your destinations at a relatively low speed. I can even do it under oars, so why you "need" a big heavy & powerful O/B to lift on & off your tender leaves me puzzled.

Maybe the big O/B is just an easy substitute for boating ability?

Just teasing - but the technique works well & I often use it in the strong tidal flows we get around the Menai Straits. Try it yourself next time using the O/B on fast tickover.

The initial approach was from the side, but it was the last 10 yards that was the problem. I have anchored there dozens of times before without problems, but conditions that day resulted in an unusually fast flow through the anchorage. I'd love to have seen you try and get anywhere near it with oars - it would have made a great addition to any "boating disasters" video

The engine weighs 20kg, which is still manageable. Shame they are not made any more - modern 4 stroke 5hp's are 26kg, which would be a bit too heavy, methinks.

You must get upstream first using eddies as I said, or by walking upstream with the dink & launching well upstream. You ferry glide to get directly upstream of the boat & then row directly upstream so you travel downstream as slowly as you can. That should allow you to grab the boat as you pass & slip the painter round a stanchion or cleat to hold yourself in place.

Have you never done anything like that? It's just basic seamanship in fast tidal waters, you know I'm a pensioner, did you really think I was suggesting rowing like a dervish at 6kts??

What will you do if your O/B ever fails or runs out of fuel?

With respect perhaps you do not know the E Head anchorage all that well

For 5 knots to be running it must have been about 2½ to 3 hours after HW. About half tide.

Although E.head beach itself is sand it is not possible to walk upstream from there with a dinghy. You'd have to cross Snowhill creek to start with then the shore at half tide is deep glutinous mud.. The unwary have been trapped and lost their lives in Chichester mud!

I dont think it would be practical to carry the dinghy into West Wittering and then along the footpath to relaunch it further up the harbour.

Due to the geography the ebb tides runs strongly through the anchorage and close into the shore at E head. I am not aware of any useful eddies at any time.

Its a lousy anchorage in some respects but it is off one of the best sandy beaches in the area.

Wait a few hours until slack water, when using the oars is a viable option

True enough, I don't know the specific area, just general comments about using low powered O/Bs & oars in strong tides, of which I know plenty.

I wouldn't attempt to walk thro deep mud these days, altho I have tried in my yoof. I even tried to carry SWMBO ashore once thro deep mud. I'd done it before on my todd no problem, but with SWMBO on my shoulders, I sank a little deeper that I expected. Struggling to release my feet without loosing my wellies it became hard to keep my balance. The harder I pulled to release one leg, the deeper the other sank, so each consequetive step became harder.

Before long the inevitable happened & we overbalanced. Full length in the mud & unable to speak for laughing. Once released of my load it was relatively easy for both of us the get up & squelch ashore. All we had to do then was walk 1/2 mile along the beach, past the locals to get to the Clubhouse, where we were able to hose each other down at the outside tap.

Great fun sailing, innit? Merry Christmas all.
