Another vote for paying someone who has the right tools to do it for you, if you can afford it. I got a firm in Devon (K Blasting) to blast the Abbot back to bare metal, a coat of Sigma marine primer (a lovely shade of pink!) and two pack Sigma epoxy DBG topcoat. However, never underestimate how much mess the blasting makes - no matter how well you cover everything, the grit will get everywhere!
And in response to the ABRO question they blast the hull after stripping it bare, that's how the Bulldogs were done.
