Boat looks great

Have you measured the transom ? Looks a little big for a short shaft.

[HighlandR]

Hi Pirate - yes it is ! that is the first thing i spotted soon as i inflated it and thought " ohh sh*... !

The engine mount bracket to the water intake plate is 45cm, and the transom is 50cm !! Should the AV plate be level with the hull or 1 inch below ?

Are the bunks level with the road, or are they set on slight incline to lift the nose preventing build up of water while sitting in garden or being towed in the rain etc ?

Having sold the other 3.8 sib ( the one with the 2 chamber issue !! ) I've managed to get my hands on a slightly newer, deal has been done and now have a zodiac 4.2 - just been delivered today.

The main reason for buying this was that it is hypalon and has 5 chambers instead of 2 ( no thoughts of putting foam balls inside the tubes now ! )

also being slightly bigger the deck space should be more comfortable, and it seems to be a good quality boat.

The floor is ply coated with grp - which is pretty heavy, but not much heavier than the old floor that was in the 3.8 so can't complain !

The boat is pretty heavy... that is the only downside i can see so far, however I don't think it will be too heavy to manage on the large pair of transom wheels, also wonder if it will get on a plane with just the 15hp - but I'll find out soon enough !

what are your thoughts on the boat guys ?

I've never seen this model before - since it is an older boat will it be possible to find out more details/ specs etc from the serial number ?
such as weight, max HP, year of manufacture etc....

How does this boat compare against other sibs out there ?

If money was no object I'd have went bought a newer Bombard or futura like most of you guys have here but for an older boat - so far it looks to be just fine for us to go fishing - safe enough to go a mile or so off the coast?

Hi the bunks are mounted level in relation to the trailer bed.
I cover the Sib over when not in use with a Honwave cover and an old tarp on top.
This set up keeps the inside of the sib bone dry and shields it from harmful UV rays.
I tow the Sib most often with the custom made Honwave cover on it.
It fits and ties on tightly.
Thereafter I use two thick 6 tonne ratchet straps over the Sib and cover to help secure it to the trailer and stop the cover coming off.
When I go to my caravan I use the Sib as a make shift trailer as the Tohatsu 20hp outboard claims most of the boot space.
All sorts go inside it safe and dry under the cover.
Even had the kids bikes and scooters and a microwave inside it lol!!

Sib looks neat!
It sure looks robust enough.
I borrowed and used a 15hp Yamaha on my honwave before I bought my Tohatsu 20.
It won't be that much lighter than you Sib and 15hp planed it fine.

" and a microwave "

Have some thick PVC tarpaulin material here ( roof panel from a marque tent ) was thinking to use that to make a fitted cover, but will mess with that later.

First i will need to modify the transom to fit the short shaft engine.

Questions :

How and what is best to use for cutting a section from the transom and then sealing the ply? - jigsaw? or was thinking maybe a router would be a better choice to reduce the risk of tear out?

then few coats of polyurethane varnish?

Should the AV plate be level with the base of the transom or just below it ?

[Landlockedpirate]

The forum will generally scream a lot if you suggest cutting a transom, however that boat is the same design as both the Futura and the Classic, both of which have cut away transoms.

I think they are simply sealed with paint, but I would also add a capping strip where the engine sits.

[HighlandR]

Hi Pirate, that's a great looking boat, what length is that one ?

I hate to cut the transom, just don't like the fact of changing how it was originally made, but I will do the best job I can to try justify it !
Capping strip on the top will protect the end grain from damage, that's exactly what I'll do.

Thinking I will seal the end grain first then just screw a capping strip on so that it can be replaced easily in future.

Just deciding now how much will need cut off !! Any ideas on the AV plate height Pirate ?

[Landlockedpirate]

Its the last of the short shaft Futura Mk3's, 4.7m.

Why not make yours the same as the standard short shaft zodiac transom at 15" from the bottom of the V to the top of transom ?

[HighlandR]

Hi Pirate, I will make it the 15" as you suggest, just busy drawing out a template for the router.

Been busy taking a few sizes today for working out the trailer conversion, and the boat is actually 4.5 Meter - NOT 4.2 as told from the previous owner

We need to move the boat down a small ramp and across some sand, a total of around 50 meters

Is this going to be a problem to move on transom wheels ??

[HighlandR]

Also - what can I expect from the 15hp outboard on it ?

[Boatnomad]

Reckon you got a good one there,foot for foot it will be heavyer than some,but it sure will last

[HighlandR]

Thanks Boatnomad, it certainly is more heavy duty than my previous sib, the material is clearly a thicker grade, the overlaps on the seam joints are much wider too, I'm very happy with it. The only thing I'm wondering is how easy it will be to move on transom wheels, and if it will plane with the 15hp !

[paddlers]

Only one way to find out, get the thing out on the water

[HighlandR]

I hear ya paddlers !

Soon as I cut the transom to fit the short shaft, seal the ply, bolt the transom wheels on, and get some bunks on that trailer it will be good to go.
