Ahoy! I keep seeing images of this Fin on several Westsail's but can't find any information on them. This image is from Pygmailion. (D. King fairing is planned)

I'm in the process of trying to buy a Westsail 32 and planning repairs and upgrades so I am collecting estimates for my budget.   1) Does anyone know the area of the hull under the water line for paint estimates and Dustless sandblasting. 2) I need to replace the standing rigging with 9/32 wire and want to get general estimate of the number feet of wire. 3) Finally since I will be moving the W32 to my yard, which are better the 4' or 5' stands? (And I'm sure I will have a ton more questions). Thanks Van
