Inflatable Fishing from a SIB
Alongside my “main” boat I’ve also been the proud owner of an Avon R310 inflatable boat, or SIB, for over 20 years. Not used as much nowadays, it still gets out several times a year and has provided some good memories together with access to fishing I wouldn’t otherwise have got. It’s also in pretty good nick – not bad for a boat that many anglers regard as a flimsy substitute for the real thing.
So where’s it seen service? Well, mainly on quiet evenings off Dunbar, offering a couple of hours relaxation close inshore when I couldn’t be bothered with the hassle of a big boat launch. However it’s also seen service launching in quiet coves near Aberdeen; off Tarbet Ness in the Moray Firth; Point of Stoer near Lochinver; west coast sea lochs; and around the Mull of Galloway. On one occasion it spent a week touring south and west Ireland, sitting quite nicely in the car boot for the ferry crossing.
I’m talking here about Soft Inflatable Boats (SIBs) and not the Rigid Inflatables (RIBs) used by most divers. For fishing purposes a SIB really needs to have a decent floor – preferably aluminium or plywood – rather than simply be a donut shaped yacht tender. The Avon is constructed from hypalon which has proved excellent and long lived, even when “cared” for by me. Other materials are available but I’ve no personal experience of them.
Pros and Cons
The biggest pro is undoubtedly its portability, and this applies in two ways. First, it can be packed away in a car quite easily (especially with a hatchback) and doesn’t need a trailer. Of course this also saves on storage space and means you don’t need a garage or driveway to leave everything when you’re not using it, although you do really need somewhere secure to leave it of course. Second, you can launch from pretty much anywhere you can reach the sea and don’t depend on a slipway or trailer access. In turn this may mean you can get closer to your chosen marks before dropping the SIB in the water.
Second biggie is affordability. You don’t need a large, expensive, engine or the costs of maintaining a trailer in roadworthy condition. You don’t need a hefty towcar, with equally large fuel bills. Once on the water a small engine is nippy but very frugal – with a lightly loaded boat I’ve never been able to measure the fuel used by my 4 stroke 5hp Tohatsu as it is miniscule. A decent inflatable can’t be described as cheap, but it’s a lot less than the alternatives.
A third pro is quite simply the fun of being in really close contact with the water, coupled with the ability to sneak in anywhere – explore caves, little beaches, etc. that a hard boat might struggle with. It’s not fishing, and it’s not that easy to explain until you’ve experienced it yourself, but it certainly adds to the enjoyment of being afloat.
Cons? – well there are quite a few to mention, including:
– no keel means it drifts fast in the slightest breeze. You can combat this to some extent by using a decent drogue and this can be pretty effective, but you have to accept that fishing in a windy day will be difficult even at anchor (as you will still veer from side to side more rapidly than a conventional boat).
– a SIB is a wet boat. In a small inflatable you will probably park your backside on the flotation tubes, or maybe 8 inches above the water. Even in a calm day you will get wet – with any breeze or chop you might get very wet. Waterproof trousers are a sensible investment and I have thought about a drysuit as used by kayakers.
– internal space is very limited. My 10′ 6″ Avon SIB is fine for one but quite cramped for two anglers. It’s OK if you’re organised, but you do need to limit your gear.
– it gets cold, especially in winter. No great surprise there, but the lack of shelter coupled with an inability to move around easily does mean you need to have proper clothing – perhaps similar to the kayaker’s drysuit if you’re planning an out-of-season trip.
There is a lot of misinformation put about concerning the safety of fishing from an inflatable. First off, the concept is relative – I don’t consider the Avon to be as safe to fish from as my Warrior, for example, but I do think it is safer than the majority of 10-12 foot long hardboats. An inflatable is a very stable boat for its size, and I’ve never felt at any risk of capsize.
– you’ll struggle to put a hole in it with a hook (I’m assuming you’re not daft enough to carry a gaff in one).
– a large spurdog, or decent tope, could conceivably put a hole in the tube if they weren’t controlled quickly. However a tube is maintained by volume rather than pressure, so a leak is unlikely to be too dramatic anyway, and a SIB will happily float even with a tube deflated. Putting a wet towel over a fish will often calm it down and reduce any thrashing about.
I think the main risks are:
– falling overboard. A SIB can be bouncy, and a hand tiller can be more awkward than wheel steering and it’s not too difficult to envisage being thrown into the water if travelling too quickly in choppy conditions. I always wear a lifejacket and use the kill switch on a SIB, not something I automatically do on a hardboat.
– flipping the SIB. A lightly loaded SIB will bomb along very quickly with quite low power outboards, and doing 20 knots is easily possible on my boat (albeit not with a 5hp engine, which maxes out at 12 knots). However 20 knots is a stupid speed to run at except in very calm conditions and might allow it to flip over in moderate seas. Using a longshaft engine will exaggerate this effect, although it’s not likely to matter until you’re over the 5-6hp mark.
– it’s not practical to carry auxiliary propulsion. The small oars or paddles supplied with an inflatable will make no progress whatsoever against a mild tide or breeze, so you’re stuck if the engine breaks down.
Key safety measures:
– Use your lifejacket and a kill switch. Always.
– Carry a small anchor with some chain and enough light rope to easily hold bottom in the areas you fish. If your engine breaks down you must be able to stop the SIB drifting, and paddles/oars don’t count as auxiliary propulsion unless you’re in a very lucky position.
– Carry flares, VHF and PLB (or at least some of the above). You’re small and won’t be spotted easily on a big, grey, sea. I personally no longer carry flares because they are of limited value compared to a PLB, are very difficult to dispose of, and aren’t practical for other outdoor activities like shore fishing or hiking.
Fishing from a SIB
Not really very different from other boat fishing to be honest. I’ve a couple of rod holders fixed to the transom, and make sure I carry only a moderate amount of gear. I tend to take a spinning rod and a 12-20lb class boat rod and find that covers most situations.
Slicing and dicing bait is obviously something to undertake with a little care – basically by making sure the knife is sheathed as soon as you’ve finished with it. I only ever cut bait on the wooden floor of the Avon, but a reasonable sized chopping board would make an OK substitute.
Comfort can be an issue both because the boat is cramped and also because you tend to sit very low down on the tube or on the seats (less of a problem with larger inflatables which have bigger tube diameters). I try and take a break ashore during the day to avoid this problem, and also use a trout fishing seat cushion to raise the seat a couple of inches and sit a bit more comfortably.
SIB or Kayak?
I’ve used both a sit-in and a sit-on kayak, but to nothing like the same extent as I’ve used a SIB. The popularity of kayaks has certainly exploded in recent years and personally I’d like to have both, but I do think the SIB has the edge for practical sea angling, particularly if you fish alone.
My biggest concern is that Kayaks do have a greater tendency to dump you in the sea which is potentially a big problem unless you are competent enough to recover the situation. In addition SIBs are faster, can carry more gear and cover more ground and are more comfortable to fish from – although you are completely dependent on your outboard.
Paddling is quieter and a very satisfying way to explore a coastline and I wouldn’t knock it, but a SIB is a better choice for my needs at the moment.
Does Size Matter?
A lot of anglers who think about a SIB struggle with the size and engine to choose. Too big and you lose the portability that is so important, whilst too small rapidly becomes limiting or dangerous when out fishing.
For single handed fishing I wouldn’t drop below 2.8m or go much above 3.4m. A bigger SIB will generally have larger tubes and will probably be drier, but the weight starts to increase quite quickly, and getting it in and out of a car boot will become trickier. For two anglers then 3.4m upwards is probably a better choice, provided you can handle a much heavier outboard that will likely be needed.
A modern 4-stroke engine weighs a ton relative to its older 2-stroke ancestors so I wouldn’t go above a 6hp for single handed use. Even an 8hp engine can weigh 40kg and I don’t fancy carrying that any distance over slippy or sandy ground. At the other extreme, a small 2.3hp outboard is easy to manage and will cope fine in sheltered water – but it will be slow.
Many people keep their SIBs on a trailer, but to me this means losing the pack up and go aspect that is one of the most attractive aspects of SIBing to me. Once you get to this sort of set up you’re comparing against RIBs and other hard boats, so the choices get a bit harder.
