Keith

the crux of deciding which route to go has got to be convenience and pos costs

Therefore, whatever you decide you have to be able to have the boat fully inflated & ready to go, pos even being able to keep the engine attached ( I dont know wether sibs get towed with their engines in place when it is so easy to remove a small 15 hp ?, this may put additional pressure on the inflatable hull)

For single handed launching you also want to be able to float the boat off the trailer, so you dont need someone else around to lift off a box trailer for example

This to me leaves you one option, a new or secondhand purpose made sib trailer or purchasing a cheap jetski trailer, circa 100 quid and possibly adapting it with wider supports to spread load

shouldnt be to difficult

I think once you go this route you will find it more pleasurable to go boating and wont be put off going out for half an hour , because you know it takes 45 mins each side to inflate / deflate

launching a boat of this size takes 30 seconds on a trailer, if engine is already in place also then you save further time

Ah, there's a problem with these - they do need quite a bit of modification to be suitable for a SIB. Reason is that the two rails which a narrow jetski slides onto are too low and too close together for a SIB (remember that a SIB hull is much flatter, even with the inflatable keel) - so a SIB will sit on one of these with the tubes resting on the mudguards, until the brackets bend down so the wheel rubs through the mudguard

Pepper2 lives on a purpose built Indespension trailer with a home made device at the back to take the weight of the outboard and to attach the lighting board to. It all works quite well - the trailer has no sharp pointy out bits, so any lack of accuracy when recovering won't snag the boat on anything. The bunks are carpeted so they're soft on the tubes, and the keel supports are also carpeted and made of a deformable material so they're soft on the keel.

And, finally, all this kit may be up for sale shortly...

Hi

One of the problems I have (and believe me I have MANY) is that I am NOT a DIY type person. I do not have the skill to make trailery things. (thanks for the PM though Phill)

Whilst I like the idea of getting a box trailer and having a 'thing' on top to put the SIB, I do not have the skill to do it myself. If I had to have it made for me then it would be MUCH more expensive.

Matiboy brings up an important point. Can the SIB be traillered with the 15hp engine attached to the back? At first I thought probably not as it would be a strain on the boat. However when I thought a bit more (not easy for me) I came to the conclusion that it must be much more strain on the boat when out on the water and we are bouncing all over the place.

Now Pepper, about this trailer......?

Sorry Keith/Matiboy, severly disagree. In the water the whole boat is working and being pushed by the engine over the whole of the transom. On the trailer (assuming it supplies the correct support for the boat) the engine is simply hanging and bouncing with the weight pulling the transom back from the top - stretching the top of the tubes. You'll find that she rapidly becomes hog backed when under power.

Yes, that's backed up by advice in my outboard handbook which advises against transport of the unit unsupported.

That's why I built the combined engine support/light-board device.

I believe that the problem is that small outboards without power trim and tilt need to be raised to clear the ground, but the supporting bracket (which doubles as the shallow water drive lock) doesn't stop the leg bouncing up. Neither is it designed to absorb any downwards shock (it's just a bit of pressed steel). I guess that power tilt and trim models are engineered much differently (you usually raise these all the way to the top, don't you?)

Keith, I've sent you an email.

Pepper, had some "greens" try that supported idea on one of our boats (i.e. o/b legs off the pin and clamped to a support, carpeted, bar). They claimed only minimal miles (<150), b'd up a 5.8m commercial Avon - and my budget. (O/b's 2 X 30 HP yammies).

Sounds like a case of Squaddies can break anything!!!

My trailer has suport directly under the transom, so that takes the load of the engine, and being a SIB, flexing is not a problem, especially as it's controlled by the support of the outboard leg which is seriously over-engineered.

Phill, yes I can understand that. I can see that it may not do it any good to trailer a long way with the engine on the transom. How about for just a few minutes though?

Pepper, seems like you have thought of that one.

Probably Ok, ? but how many times "a few minutes" ?

Pepper, quite correct, same group took out a portable sounder, because it had 4m of cable connecting the unit to the transducer they thought that it was a towed fish, threw it overboard, ran it through the props.

P.S. the <150 miles was total claimed over eighteen months !
