Bombard 380 vs F-Rib vs ?? - Help choose right boat.

I have received some great input at this forum regarding Remote vs Tiller steering and the more I thought about the boat the more i realized that I need to start selecting the actual boat as my daily launching logistics are a bit special. I think I'll go for the new Suzuki 20HP as it's 44kg and it should be manageable. I don't know if the engine has some good handles for lifting it down to the beach though?

Here are the boat options I have found with a 20+HP rating and semi light weight:

F-Rib 360 - 48KG (Max 25HP - Sadly uneven floor)
F-Rib 375 - 62KG (Max 25HP - Heavy, but flat floor, good)
Bomb. Aerotec 380 - 43KG (Max 25 HP - Lightweight, V Shaped floor as minus )
Zodiac Cadet 350 ALU - 67 kg (Max 20HP - Heavy)
Zodiac Mark 1 Alu 350 - 64 kg (Max 25HP - Heavy)
MERC, Air Deck 320 - 46 kg (Max 20HP - Too Small?)
MERC, Air Deck 320 Fish - 49 kg (Max 20HP - Too Small?)
Honwave T38 IE (380) - 48 kg (Max 25HP - Semi V floor - Too large?)

I'm going to keep the boat inflated during the summer months. And it will be located very close to the sea.
I have tried to show my main obstacle in the attached drawing.

There's a 2 meter drop from the plateau where the boat is stored and down to the beach. Lifting the boat and engine down 1 by 1 is the only way to get it to the launch area. I'll have to carry the boat over some rocks (two person job) and this is why i'm looking for something pretty light.


I would like the boat to both be as fast as possible while I use it with friends for fun (Hence my 20HP rated boats). And also comfortable for family trips. Catch 22 it seems. The most efficient boats like the 380 and F-Rib 360 have uneven floors and my guess is that they'll be uncomfortable for the family runs(here comfortable refers to being able to use the floor surface for resting and roaming around for smaller kids while anchored and so on?) The F-Rib 375 has a flat floor but is heavy. The same goes for the ALU floor boats that are nice, but it would be annoying to deal with the floor if remove before lifting the parts to the launch area right? It seems hard to assemble these ALU floor boats.
My strategy is to not deflate the boat and only remove the engine after the runs. It will sit on the raised plateau with a boat cover while not in use.

I have read the 'Which sib' post and almost any other relevant posts and it seems all boats are compromises.

Can't you build some sort of "slide" ?

It's interesting that your launch site is similar to how the previous owner of my old Aerotec described its original use in Ireland.... two person launch over a boulder/rock area of foreshore. My boat was covered in small grazes on the black floor skin and these were much of the repair work I've done.

I'd say from experience anything heavier than a sub 45kg air floor is going to be a struggle in your location and anything getting up towards 70kg will be awkward even with a third person.

You are right that for family room, comfort and walking about space there is nothing like a 3.5m alloy floor SIB and that's why we spent some years with a hard floor SIB.

The difficulty in choosing is the main reason we've gone to some trouble to get an Aerotec to take on 2wks holiday alongside our existing flat air floor Zodiac... by the end of the period we'll know for sure which we want to keep.

If that was my house (presuming it is yours?) I'd forget a SIB and get a small 4m RIB with a 30 or 40 on the back, clear the rocks on the beach area and build a simple launch ramp (pair of scaffold planks, sand ladders etc) rolling the boat down on a simple launch trolley, winching it back up if necessary.

Much simpler surely for a few hours work?! And a 4m RIB will outperform any SIB by a long way.

If this does not appeal then I cannot help thinking you are over-analysing things. As per previous topics it all comes down to the same basic choice and compromise. 3.4 to 3.8m SIB, 15 - 25 engine etc, etc.

Are you inflating each time? No. So a solid floor is no issue.

Two people can easily carry or roll down on transom wheels any typical SIB over that distance.

Have you sat in a 3.4m SIB? There is no room for roaming!

A solid floor is good for the feel underneath but it is hard (literally) for kids to sit on so a mattress or similar may be needed.

Don't see the Aerotec inner V as a disadvantage. It is much deeper and safe feeling for kids in the bow, comfortable to kneel on and driving from the tube much more ergonomic for bracing against. Having said that, again in *your* circumstances a solid floor would be the one I'd choose.

Really, I'd read the sticky (again) or topic below:

Advice on which SIB / engine combo works best ..

It's all been said a gazillion times before but all boats are a compromise.

But coming back to your (dream) house, just clear the rocks!

Lifting and carrying a 20hp 4 stroke is easier said than done, I certainly wouldn't fancy trying to get one up and down over those rocks on a regular basis.

I'd suggest going to to a dealers to try moving one around, and then imagine yourself with 2m drop over boulders, before you commit to buying one.

Assuming that you own the flat plateaux at the top where you are storing the boat then I think Max is thinking along the right lines. Either (a) create some sort of temporary wooden / plastic slide that gets it over the rocks using a winch to haul it up/down OR (b) construct a big davit/derrick which would let you lift the boat and swing it out over the rocks and lower it down. Assuming of course that you can't remove the rocks.

Rocks... I'm thinking coastal defences!

May be heavier but a boat that would stand winching/dragging over smooth boulders is a Poly boat like this...

Pioner - Pioner 13 - versatile, tough and easy to handle

They will take huge abuse and may be better than a SIB or RIB in this location.

I'm a bit of a poly boat fan, but I can't see you just dragging over those boulders!

Well OK perhaps some sort of wooden rail to assist or tarp draped over the boulders... but if there is a risk of bumping the hard stuff those poly boats shrug it off really well.

Thank you so much for all the great info! - I have commented inline below.

I have thought about ramps and have researched the topic. Because of rules regarding the coastal protection the ramps would have to be temporary and each section would have to be 6 m in length to reach the beach. Such a ramp section in aluminium would weigh approx 70kg, so each section would be very hard to handle.

Great info! - Thank you. It will be very interesting to hear your results from the two weeks testing.

Yes it is my house
This is also my dream to have such a setup, but it has proven pretty hard. The rocks can't be removed as they need to be there for coastal protection, so the ramps would have to be on top and they would be long. Each section about 6m, a scaffold plank in this length will be very heavy. Also there's not room to maneuver at the beach, if the boat is 250kg with engine then it will probably be hard to launch and turn with a pair of launch wheels?

I'm very sure i'm over analyzing things, but it's very important that this project turns our to be a good experience.

The plan is to not inflate each time. I'll just top up the boat pressure if needed at the storage plateau. The only issue from a solid floor is the weight.

Thank you for the floor surface info. The hardness on top of the unevenness is why I'm hesitant regarding the F-Rib 360, it must be really uncomfortable.
I haven't sat in a 3.4m SIB, since my kids are very small (1 and 3, I do not see them as taking up much space, so that's why I wanted something just big enough. I have heard that kids grow, so maybe it's good with some additional space

Thank you for all input Max! - Very much appreciated. I know my question is generic and covered here many times. It just feels a bit different as I'm not using a trailer or car boot as part of the setup.

Good idea, we'll try this Does anyone know if the engine has some decent handles??

Yes it's my plateau, and you're right I can't remove the rocks.
I have seriously considered a large swing davit, and a SIB/RIB setup with a single point for lifting. It just gets very complicated real quick. I haven't given totally up on this idea, but it might be a larger future project.

I looked at the Poly boat, and I don't really understand the concept. It's both heavy and and not capable of much engine power :/
