If the pump is not damaged, use the money you would use on installing a Berkeley and buy a Place diverter for the WJ.
The WJ will handle just about anything you can throw at it without complaint.
As for the hull... I have a love/hate relationship with mine. I absolutely hate how it rides unless the water is between flat and mild wind chop, anything rougher and it is horrible. Now on the other hand, I love the uniqueness of the T-deck and the sexy shape of the hull.
And for an added bonus, don't plan on packing too much stuff in it, it's very cozy inside.
