1980 Colvic fishing boat

Burnham-on-Crouch, United Kingdom


Grayling is a characterful example of the ever popular Colvic small motorboat range, well suited to pottering around on rivers, esturaries and light coastal work. She has a taller wheelhouse than standard for improved headroom and is fitted with a more modern Nanni freshwater cooled engine. Although she could be improved with some fresh paint and varnish in her cockpit she is a good example of her kind ready to enjoy and is fitted with bilge keels ideal for drying moorings.
