Broker comments

2002 Sealine S23, one of the most sought-after sports cruisers in its class. Combining sporty performance, stylish accommodation, and the legendary Sealine build quality, this is the perfect boat for weekends away, family cruising, or simply enjoying sunny days afloat.

A very well presented trailable motor cruiser with an economical 170hp Volvo Penta KAD32 diesel engine.

Ideal first boat for someone looking to enter the world of sports motorboat cruising.

Reason for sale: The owner, who is over 75, has found that his osteoarthritis has got worse this year and consequently he is finding it difficult boarding Jambo. He has therefore decided that the time has come to give up boating.
