Please can anybody recommend a boat insurer that will cover an agreed amount rather than the secondhand value? It could be quite easy with an old boat to get into the position where the potential cost of a major repairs could exceed the sum insured. thanks.

Tim I have been insured with Bishop Skinner for a long time and have Heaven Sent insured with an agreed value of £5000.  I have had them settle several claims both after collisions and from the boat somewhat disintegrating at Tenby and I have not had an issue regarding the value.

Thanks Andrew. Will give them a ring.

Yes Bishops Skinner the's place to head - very helpful people too!

Have insured my 2 Merlins - 235 & 1939 with Bishop Skinner for many years, with 235 for £500.
