Hi James,

My apologies if I had missed this earlier in the thread, but are you able to keep the boat assembled when not in use, or would you need to disasemble each time?

If you are able to keep it assembled, why not keep it on a hand dolly with beach floatation wheels? This would be much easier on the boat than using transom mounted launching wheels. With those steps, transom mounted launching wheel would place a tremendous amount of stress on the transom when trying to get up and over them.

I have a 4.7 meter SIB with a 40 hp which I had originally envisioned hauling in the back of a pick up truck, and assembling and disassembling with each use and using launching wheels to launch. While I can do it with another fit person, it is still a lot of work of work (my boat without motor weighs somewhere around 180-200 Kg). The the disassembled boat, motor & fuel tanks pretty much filled the box of the pick up truck, thus requiring a utility trailer if I also had a bunch of camping gear that I wanted to take.

I have since bought a trailer and keep it on that which is much more convenient, but does require the extra storage space (which may be worth looking into). Once I was able to keep the boat assembled it go used far more frequently than when it had to be assembled. I found that other friends were willing to help me assemble the boat once, but not twice

Now that I have a trailer, I am wondering if I should have gone with the 5.3m version of my SIB.

Transom wheels can be fitted in the water but they are a bit buoyant so it isn't easy and they are not very useful. The engine is too heavy to remove without a winch which I have in the garage. In practice, dismantling the boat after use is not worth the effort and mine stays inflated on a trailer with the engine attached when not in the water. The trailer is too long to fit in a garage with the boat. Mine is therefore stored in a boatyard when not in use. Hope this answers all of your questions. Feel free to ask more.
Where abouts in Mallorca do you use it?

Thanks for the replies guys!

After all that I went for a RIB! First of all I won a mk2 Futura (4.2m with 50hp yam) on ebay, but fortunately it wasn't anywhere near as good as described so I didn't buy it, but it did enable me to test drive it, and tbh I was left very disappointed. Now I am sure this is mainly due to the condition it was in, but still. Anyway, I have now ended up with a 4.2m rib with 50hp Tohatsu 2 stroke injection engine, and despite me saying I cant use a trailer, I am and I made special ramps for it to go up the steps on the slip way!

Thanks for all the help though! lol

Pictures? How are you pulling the trailer up the ramp? Did you get checked out on the hoist?

Yea the crane was serviced and takes 2 tones! =D

I made ramps using scaffolding planks so the trailer can roll up the steps onto the slip way. I have only brought the bought in once, and we used the winch on the trailer to an anchor point opposite the slip way to pull the trailer up, but what a pain in the back side (with 3 adults pulling!!!) we really struggled to get it up the ramp onto the slip way! The ramps I made flexed A LOT in the middle with the weight of the boat/trailer so next time I will put a breeze block in the middle of each plank to help stop it flexing.

I am going back out there in a few days so will actually try a different method, as my friend who helped me suggested. I know it sounds stupid that we didn't do it this way originally, but basically the plan is to crane the boat straight in and straight out of the water! Once we got the RIB onto the boat deck my friend was like, how far down does the crane's hook go, sure enough lol it goes right to the water, so in hindsight we should have tried craning it straight out of the water! The problem is the front of the RIB will hit the step/slip way so I plan to attached a rope to each ski/towing eye and have two people holding the RIB backwards so as its lifted the front clears the step/slip way. I hope this works, fingers crossed it will as it should make life a lot easier and that way the trailer can stay on the boat deck above and never have to go in the water!

Also as a back up plan in case we struggle to hold the RIB back to prevent damage to the front of it on the step/slipway, I have bought a pulley, this one in fact... 50MM Awning Pulley Single Nylon Sheave Fixed Elongated Eye

The back up plan is to attach a couple of meters of rope to the anchor point (eye) in the wall opposite the slip way and put the above pulley on the end. Then lower the crane's hook straight down to a couple of meters above the floor and attach a length of rope to it, and then feed this rope through the pulley and then attach it to the trailer in the water and let the crane do the hard work of pulling the RIB/trailer out of the water!


Here are a couple of pictures for you...

Did you consider a 50, or have you tried one? I'm trying to sell my 40 so I can get an ETEC. Wondering about 50 (max. recommended) or 60 (Max. allowed); whether the difference will be noticeable. What year is your 60?
Apparently the 60 has a water valve that alters the exhaust tuning. I'm wondering if the extra complication is worth the potential for extra trouble when it fails or needs service/adjustment.

I'm staggered that a 60Hp Etec can only reach 32 knots.

I was surprised too, but to be fair Zodiac quote 37.3mph (32.4 Knots) as the top speed so it must be! You know how it is though, it always feels faster than what your actually doing! lol

FWIW, I went from a 15 pitch to a 17 pitched prop on my 40 and only gained about 2 mph, maxing out at about 31 mph. I think the hull is main the limiting factor now. I'm hoping more HP might gain me a little more speed, but also will allow me to reach close to max speed with a greater payload, i.e. 3 or 4 fully kitted divers.
Which again makes me wonder if I need to go with 60 HP, or if 50 might suffice.

I would say if you can afford to get a 60HP engine then do it. If your buying a second hand engine I cant imagine there will be much price difference from 50hp to 60hp, though I am sure there will be a lot more 50hp engines to choose from!

Another reason why I would go for a 60hp over a 50hp is because I don't think a 50hp will cut the mustard after coming from a 40hp, its only a 25% increase, where as the 60hp is a 50% increase in power!

Good luck either way!

I'd say that an Etec 40Hp would be just about the worst possible engine to have on a Futura - I now doubt that the 50Hp would be much better. The 40/50/60 all weigh in at a mammoth 110kg!

IMO, it's the sheer weight of some of these modern outboards that's the limiting factor. I'd say that they are probably more suited to a solid hulled vessel if it's out and out performance people are after.
