we had a coastline 6 meter a few years ago and it was a great boat! very capable when it gets lumpy but not the fastest boat in the world.
think they have done quite a few inboard boats in their time although ours was outboard boat.
they moulded deck gives it a good finish and when i spoke to Brian before we bought our current rib, seems they are making a few changes and bringing out some new console / seat designs as the old ones were a but angular and in need of an update!
i still think with the tapered tubes they look great on the water, ours had white and blue tubes and i still think the colour scheme was great!!
they are involved with ribex this year so expect to see a few of them there. built on the Hamble still i think.
would be well worth a look!
