Questions from a new potential boater!

Hi -my first post after browsing for a while

I'm looking to buy a SIB for use in North and East Yorkshire mainly.

It will be a mix of river/lake slowish cruising and "light" coastal trips from Humber and Yorkshire coast harbours.

Boat size will be 3.1 to 3.5m usually with 3 adults.

Just a few random questions please -

Given this profile would a 5/6 HP or 9.8/9HP motor be best suited considering weight/economy/speed.?

Is there a case for going for a 15HP on the basis it will spend at least 75% of its life at very low revs?

What fuel economy is likely for these engines at a) 6kts river and b) WOT(ish) off the coast?

What would be the license costs for the River Ouse?(if any)

Do SIB require any form of certification?

Are there any marinas on the Ouse which offer dry storage for the outboard so we don't have to transport it by car each trip?

Thanks for reading this and any replies will be gratefully received - there is clearly a lot of expertise out there on the Forum!

Welcome to the forum.
I'd personally go for the biggest engine you can carry. my younger brother uses a 25hp Soozie on his Avon and manages ok.
You don't need any certs or qualifications to use a SIB but its best to do one of the RYA Powerboat courses to pick up the basics.

Thanks Chewy

I'm unsure about the size of boat to buy. Can someone please point me to some dealerships I can visit to see a selection of inflated 2.5 to 3.5 metre boats to determine their actual "comfort" with 3 adults and some kit plus perhaps a fuel tank. I am aware that most boats do have a weight limit also which may override the physical space issue.

The visit needs to be within 2 hours or so drive from Harrogate on a weekend.

Any suggestions please?

Also....newbie type question (!!) When carrying outboards horizontally in a car, is it best to put them in some form of container? Can they be prone to leaking fuel/oil when not upright?

Dealerships within 2 hours drive of Harrogate,, ,skipton ,castleford,whitby ,Hartlepool,Hull and Humberside even the lake district .
The river ouse ,,British waterways took it over about 15 years or so ago and there is now a fee ,even below Naburn lock a few miles down stream from york which is then a tidal section a fee is needed .
last time i was on the river ouse at york was at the annual viking festival one sunny crisp cold febuary morning .

there used to be 2 marinas just south of york ,Naburn marina and one across the river near Bishopthorpe ,

with regards to carrying an outboard in a car ,no problems ,,though ,,
4 strokes need to be layed down on one side only ,, there will be a warning sticker that tells you which side ,
2 strokes any side ,
though unless you run the carb dry before you pack away ,either disonect the fuel tank and run dry or use the drain screw on the carb there can be a slight wiff of petrol not much to worrry about though from most engines,

Boat Owners Marine Store. at Castleford are Honwave Dealers they always have a few in.
there. So you should get a good idea for size inflatted and deflatted. address is 16 Methley Road, Castleford, WF10 1LX Tel 01977 735400.

Or the slipway at bishopthorpe although currently they are knocking down the showroom and other buildings and constructing fab new ones.

to run a sib on the river you need a Boat safety exemption certificate lasts one year. And a river license you can get one day ones or a 30 day occasional use, depends on how often you intend to enjoy the river.

SIB and engine

For 3 persons I'd say you need to be looking at 3m minimum boat size. Our 2.8m Zodiac is great with 2 people but a bit cramped with 3.

Also the 6hp engine won't plane with 3 people in the boat, although it will push it along fine at low speeds.

So I'd say go for a 3m+ boat with an engine of more than 6hp....unless you don't want to do over 6mph.

There's a big engine weight jump from 6hp (27kg) to 8hp (37kg). One exception is the Tohatsu 9.8hp two stroke if you can get a good used one, it weighs only 27kg.

A 6hp motor will be fine for inland use, but you'll probably with you had more when you're on the sea. A 9.8 2-stroke would be a good choice, and a 15 would be OK, but probably more than you actually need. Fuel economy with any of these is pretty much irrelevant - the biggest problem is forgetting to fill up because you do it so infrequently.

If you are going to be inflating and deflating the boat each time, then light weight and convenience is the key to making your day enjoyable. Unless performance is key, get the lightest motor that will do what you need it to. A 15hp 2-stroke is manageable, but a 9.8 is much easier.

Likewise I'd definitely suggest an airdeck for your type of use. Something like a Quicksilver 340 would be good, or for a bit more money you could get one of the Honwaves or best of all the Bombard 380.

I've had inflatables in a variety of combinations of floor type and motor size, and now have a Bombard 380 with a Tohatsu 9.8 2-stroke. It's underpowered, but will easily plane with me and two kids and will just about get on the plane with 2 adults and 2 kids. Best of all it must be the lightest package for the size and is really easy to store, transport, setup and derig.

Thanks everyone....some valuable advice there, its a refreshing change as I also post occasionally on a pilots forum where useful answers to "newbie" questions are rare and consist mainly of patronising w***y waving bores!

Just another if you please......is SIB-ing permitted on any of the many reservoirs in Yorkshire?

To say how many reservoirs ,lakes and dams there are in yorkshire ,there are very few if any that allow the use of the general public using powered craft,mostly they are private sailing clubs or used for drinking water ,even the watersports centres dont allow powered craft except for there own rescue boats ,there maybe some in south yorks and i think there is a couple of lakes over the pennines on the lancashire/manchester side .
the lancashire sibbers may have a better idea ,, Sale water park and Hollingworth waterpark spring to mind ,,,(not often us yorkshire like going over the pennines into lancashire ,war of the roses ,,lol.

Newbie question - Do you always use a slipway ramp to launch your SIBs or is there another approach which can be used if a pontoon is available? Probable boat will be 3.1/3.3m and 6HP

I am talking here about river/lake launches where a beach is not available.

Assuming the boat has no trolley, are launching wheels the way to go?

I'm asking these questions in preparation for the "we should buy a SIB" pitch to Mrs Hamble Flyer !
