New here. Advice please.

Hi. I am new here so hello to you all.

I am looking to buy my first SIB to carry two adults and two young kids (and occasionally just four adults) around the sheltered waters of the scottish west coast. I have just aquired a Yamaha 25 2 stroke (autolube 47kgs) and am looking for a boat to match.

I have narrowed my choices to a 3.5 - 3.8m SIB and like the look of the Honwave T35 al'floor. The specs say max 20hp. My 25hp is within the weight range but slighty overpowered. Does this matter?

I will want to occasionally get four adults on the plane. Do you think this boat is a wise choice for my needs? They are available for £800 new. Does anyone know of any special offers for any less? Is there a comparable boat that's better value? Has anyone got a used one they want to sell?

Thanks in advance.

Chris

Air floors must be pressure topped to work as expected, that's 10-12 psi, easy to reinflate on land, once at sea specially at late afternoon will experiment deflation due to temp variation issues, having the Honwave a V medium deep and not a flat deck, keel re infaltion to those pressures is a bit foot, hand pump unconfortable.

If you plan on to inflate/deflate and pack your sib on every outing an air floor would be the way to go. A 350 sib is too short for a 25 horse and 4 passengers, but if wanting better sib engine performance go for a alum panel floor sib 380-420 range. Will perform much better.

Will take more time to assemble/disassemble than the Honwave, other option is to leave it assembled on top a proper trailer including engine sitting on back transom.

Happy Boating

A quicksilver 3.8 HD would fit the bill well.

check out the bombard aerotec 380 with inflatable "v" keel. I own one and it performs superbly

Hi

The honwave is great fun a and has wider tubes than the others making it more stable and is Honda's loss leader.

Obviously I can not recommend you putting the 25 hp on it but if your question was have I been aware of people doing this then yes on the 3.8 meter ( max 5 people max engine 20hp) but not on the 3.2 as that has a max rating of 15hp and trust me a 10hp with 4 people is enough unless you are v v brave and even then I would need it to be flat calm. Oh and just to be clear on this I am no chicken as I put a 150hp racing engine on a shetland 610 and took it to over 55mph and the videos are on youtube.

re ali floor.

sorry unless you are wanting to fish then this is simply not needed

options

get a smaller engine and go for the 3.2
spend another £200 ish and get the 3.8 air V floor
buy the package and get a fee electric pump and get addicted to boating that will end up costing you tens of thousands over the next 20-30 years as everyone upgrades!

ps happy to quote on request.

pps you could collect from milnthorpe if that makes it easier for you over the next few weeks.

Agree with those recommending a 380 with alu-sectioned floor. The Quicksilver 380HD mentioned would be a good option. It is a good size for 4 adults and is rated to 25hp. You will find iit hard to find a full Airdeck rated that high. From experience, anything under 3.5m would be a bit cramped for 4. Please be aware that if you overpower a Honwave or any othr SIB, both your warranty and insurance would be void should anything happen.

bombard aerotec 380 is rated to 25hp

And the futura (airdeck)

Hi Stig1973
Please tell me about your Yam 25? performance, weight, running costs? etc
Iam close to buying one, to go with my aerotec 380. A dealer is trying to convince me to buy a mercury 20hp 4 stroke as weight will be similar to my existing Yam 15. Really unsure what to do. Any advice would be greatly appreciated

Hi deekus
Yamaha 25 2 stroke

Weight is either 47/49kg

Running costs - £10-£20 petrol per day
depending on speed

Performance, fantastic !
Flat calm water it feels fast enough, choppy water and you would flip the sib if you kept wide open throttle

Fantastic, however it's not easy to lift in/out of the car alone

Hi Stig. Great news about the Bombard being rated to 25hp,I didn't know that. If you can find one within budget, it would be a sound option.

I agree Ex treme..... But it's Deekus who's got a bombard and looking for a 25hp outboard, I've got one already.... Lol ;-)

If you over power a boat you risk the insurance company not paying out in the event of an accident. Since you are worried about overpowering for safety reasons then you will be worried about overpowering for insurance reasons. Ask an insurance company if they will insure you and how much it will cost. If they won't, buy a boat that suits the engine like a T40... no mine isn't for sale
