Sillinger were supplied by Avon in the 1990s - I saw a load of them in the Avon factory about 10-15 years ago. Looks like a re-badged Avon 4.65 Supersport. Definitely a leisure boat with a medium-shallow Vee hull. A few of my mates have had them over the years - they're good for running around on the estuary or in calm water, but don't compare them with the 4.7 Searider as they can be really hard work in choppy seas. Due to the shallower Vee hull, they tend to climb over the rougher seas and slap the hull down, rather than cut through.
Depends what sort of use you have in mind.
