Hunter 701 fitting an inboard.

Well don't blame me for the heavy engine hung off the end ( worst place ) of a boat which already has inbuilt design drag then :)

And please don't use my website- that was a particularly shitty thing to do and speaks volumes about you.

What exactly are you trying to say? That the 4 stroke is heavier then the listed weight, or that even though they weigh the same, somehow the 4 stroke weighs more.

For someone that claims to have been an aerospace engineer its kind of odd that you believe that two engines with the same mass could possibly have different weights. Honestly at this point you're just trolling.

And as usual you can't help but try and take a dig at other peoples choice of boat.

I dont think he actually made it as far as being an aerospace Engineer ........ He was the one who looked at the prototype of the Hawk and said "That'll never fly. The engine is too heavy. You won't get it off the ground"


I think you may have hit on the science underlying the outboard weight argument though. The brochures etc really give the mass ... in kg , not the weight That would be in Newtons. In Seajet's Cloud-cuckoo land gravity is less therefore his engines weigh less !
 
Try lifting a two-stroke 5hp compared to a four stroke one.

Actually I sat in the first Hawk, XX154, on the evening before it's first flight by Duncan Simpson the next day - seemed pretty airworthy to me, but I was a 12 year old schoolboy at the time - it's the subject of one my little articles.

You adoring fans can read most of my life story if you like, soon to be published ( really ! ) - I'll keep you informed. :encouragement:
 
Weight of a new latest model Yamaha 5hp 2 T 21 Kgs. Yes you can still buy them if you really want one! Ancient mariner Andy will probably want to include his purchase of an older model in his life history:encouragement: This weighing nearer 18Kgs but realistically they are as rare as hens teeth now.

Weight of latest model Suzuki 5HP 4T 24Kgs.

Weight is really no longer an issue when comparing 2T and 4T new engines that are available at this Hp rating!

I am not sure you would notice much difference if you hung either off the back end of a Hunter 701. But I would not want to use either on a lightweight roundtail roll up dinghy/tender!

This still sways me to recommend the lightest power to weight ratio engine the Johnson/Evinrude 4HP 2T. Not quite as rare as hens teeth yet! weighing only 17Kg. http://www.ebay.co.uk/itm/Evinrude-outboard-4HP/262983612407

Can I just say that the picture of Vics boat seems to show it can carry the weight of the heavier big sister gear box engine (available as 5,6 and 8HP variants)quite well. There is little sign that the boats equilibrium is contrary to its waterline. I would not expect transom drag to be any more than the designer envisaged.

I'd be happy to list the design snags of the Anderson 22 ( and 26 ) - no such thing as the perfect boat, just the A22 seems the best of its format so far.

Transom drag is maybe not a problem but distinctly noticeable on the A22; when one has an inflatable dinghy under the cockpit, a few crew and the cruising junk like kedge anchors onboard the stern does sit down and performance reduces by half a knot or more.

This is with a two-stroke Mariner 5hp, which is easy to lift in and out of the well; four strokes are not !

When racing it pays to have crew on the foredeck to keep the transom out of the water.

So as the 701 has a much narrower stern and a transom hung outboard it seems reasonable to suppose transom drag affects it worse.

I apologise for my comments about the Sea Wych, each to their own - but a heavier engine hung off the back of a smaller boat seems likey to incurr transom drag.

For the second part, I think nearly anyone who's racing stows the outboard down below as close to the keel as possible. If cruising, I imagine a few kg wouldn't bother the majority (not all) that seem to sail everywhere with poorly trimmed sails and a terrible rig setup.

As for the designs of small boats, as much as I can appreciate the design of older hulls like the Anderson as a beautiful thing, I would say that for both racing and cruising, the newer designs do it better.
Plus most examples are now very tired and in need of a good bit of money spent.

For example the Bente 24 (I know its 2 feet longer, but its just an example)
http://www.bente24.com/wp/24ben/?lang=en

Lots more stowage space, a powerful but easily handled rig, fast off the wind sailing with the asymmetric, much easier to get around on deck, enough stowage.
Also benefits from nearly 50 years of advancements in understanding of the materials and construction techniques.

If I was downsizing and could afford it, I'd seriously consider something like that.

Stowing the outboard in the cabin was spiffing in Uffa Fox times, but in an A22 is a serious obstacle for getting forwards in the cabin, and a possible leak source for petrol.


Having the engine stowed and the well fairing plug fitted - or if one's really keen, the engine taken ashore - seems a better bet for racing - nb for cruising there's also the 2hp tender engine on the pushpit.

I was sorry to see you and VicS arguing, because you really have a lot in common.

The Anderson 22 is a small yacht with a sleek appearance, excellent hydrodynamics, sparkling performance, remarkable seaworthiness and an impressive track record of passages, including ocean voyaging. The Sea Wych is also a small yacht.
 
Hi. OP here after a very long absence... Well my plans for my 701 have gone nowhere to date.. birth of daughter 3 scuppered any real time last year.
Thank you for all the info and thoughts... I'd did have her looked at by a local boat builder who said that a lot of the work was done and she likely had an inboard previously.. he suggested if I could find good s/h parts and was willing to lend a hand with fitting I could likely get it done under well under 2k... But as many have said I'd be very lucky to get my money back and with the need for something bigger looming it's been put aside for now.
Cheers again.. I'm sure with more time on the water this year I'll be back with more questions... Jim

Elefatnman,

please feel free to PM me for an e-mail chat, I'd be the first to admit the Anderson 22 was a modifiied rip- off of the Hunter 701 !

The two are hard to tell apart for a casual onlooker


sorry if not making much sense my normal back pain is REALLY kicking in now - the 701 has a much thinner transom, along with no well and masthhead rather than 7/8tths rig and an hyrdaulic rather than manual keel winch.


Several late A22's tried various inboard engines but it i's fair to say they were failures; like the the A22 I suggest a well maintained Mariner 5hp two stroke - light enough to lift and stow - with a remote fuel tank and charging coil - is best bet -have to go as in agony now.

Andy

Hi Andy. Appreciate the thoughts and offer. And I wish your well with the back, I too well know this affliction having currently got issues with two discs my my lumber back meaning I get sciatica and muscle spasms... Both of which are horrible.
Thank you. Jim

I’d also like to wish Andy well with his affliction.
