Oh , so the thing is called a SeaWych. Sorry but they are ugly. The Slug may well be aptly named but she has pedigree and looks the part. Drop the diesel overboard and get a four stroke.
not many bilge keelers look good out of the water
the fact that I can sail the slug is 2 feet of water is a great bonus
The inboard has been wonderful
Its true in flat water where the prop can be working at a reasonable depth to deliver everything it has got to give to the boat and outboard can push any boat along at a good speed
It also has the advantage of being off to one side so it is firing all its power away from the boat.
The slugs prop is right under my feet - in front of the tiller
That has two effects - first there is some loss of forward power because the flow from the prop runs into the rudder - no idea how much it is but it must disrupt the flow
the upside of that is that when you want the boat to respond to the tiller - it does it
Then the prop on the slug is big - much bigger than an outboard prop
it is turning deeper in the water - with all that weight of water above it to make it more effective
and it is sweeping a bigger area of water - but moving it more slowly
when a wave tries to push the slugs bow out of line then the rudder working in the flow from the outboard delivers that turning motion.
I have tried pushing through big waves with an outboard - it was not very satisfactory
I know that an outboard on the back of the boat will sometimes require me to place my hands on both the outboard and the tiller to vector it
I sail single handed - so coming into quays needs to be done slowly and under control. Onre hand for the tiller, the other for the mooring lines
The turning prop is well out of the way of errant lines - all my mooring lines are bouyant
In my opinion there is no doubting that the advantages of an inboard are massive when it comes to single handed sailing and safety in a small boat.
But.... keeping an old one going is stupidly expensive
so I really would like to keep the inboard
I have now had the first assessment and guess at a price for fixing it from the engineer in Wisbech
the first email, which was a long one ended with
"I am sorry the news is not good
the second email, which was much shorter ended with
"I am sorry the news is bad
I wil put the emails on my website if anyone is interested
