Thanks Gurnard,
I'm convinced now it should ok .
Your 3.3 seems to get along quite well with all that weight, is it a 2 stroke?

Yup..its a 3.3 two stroke.. 13kg weight..so light and small. The seago (small grey inflatable) is 2.7m slat floor..so doesnt plane.. but it wouldnt surprise me if an air floor version wouldn't plane with that engine and just me on board..?

The red boat at Ailsa Craig ..its a 12ft fibre glass job..around 200kg weight and a 4hp is the manufacturers recommended size engine for it..because it is a displacement boat

So saying all this..if you have not bought the 3.5hp.. I would suggest buying a bit larger. However ..if you already have the 3.5hp.. I wouldnt worry..its safe enough in the areas you mention you will be using it

The other good thing about it is... the fish dont seem to care what size engine you have.. and that appears to be your use main for the boat

I remember I got my first Sib - a 3.3m Plastimo with aluminium floor.
I had a brand new Johnson 2.5hp 4 stroke on the back.
My old man nearly fell off his chair laughing when I told him I would be accompanying him sea fishing down to the Mull of Galloway.
"That'll no stir your tea" he scoffed!
Any ways we went out fishing and my old man kept a watchful eye from his boat to make sure my little set up was going to get me and my mate back to Port safely.
There are strong tides around this area as Luce Bay empties on the turn of the tide.
The 90 is kg Sib with around 220kg of personnel / gear did toil against the tide at tine but ultimately overcame the tidal currents - in the end.
I now use a Tohatsu 20hp 4 stroke on a 3.5 aluminium floored Honwave.
I use a 2.5hp Suzuki as a back up / trolling motor.
This is the identical engine (rebadged) to the Johnson engine I had on the Plastimo.
The Honwave has much bigger tubes and is considerably wider.
It is only 20cm longer than the Plastimo but much more buoyant.
Despite being considerably heavier than the Plastimo - the 2.5hp powered engine shoves the Honwave along much easier than it did on the smaller Sib.
I attribute this to the fact that the Honwave is more buoyant hence less drag.
In the Sub 4 hp class you are touch and as to whether your Sib is up to making headway against tide and wind.
Just make sure you don't overload it and be mindful of tide and wind etc.
I'm sure you will enjoy it.
My safety concious old man now goes out Sib sea fishing on my Honwave more often than he goes on his own boat.
He is now contemplating getting one!

Thanks kaman. I'll be keeping an eye on the weather and tidal reports.
Fortunately I am able to get out any day I choose so I'll be mindful of what's the state of the sea and wind. First few times I'll won't be too adventurous and make do with a couple of hundred yards from my launch point to see how the set up performs.
If the sea is calm l might go out a little bit further.
I'm not too bothered about speed but as you say as long as I can get back against the tide and wind then that will be good enough for me.

If you haven't bought the 3.5 HP engine yet, better go for a 5 HP instead, small in size, weight, will handle much better than any 3.5 which is a basic engine.

Happy Boating
