What I did was talk with others at my marina and let me tell you I got a wealth of information. This is my first boat and I paid enough for it that I don''t want to mess things up but still want to save some $$$$$$.
I will be doing my own heads, holding tanks
, through hulls, ac, and water tanks.
Once things were explained it became quite evident that it''s really not that hard.
The only part that I''m leary of is the engine. That I may let the marina hauling my boat do. I did ask if I could be present when it''s done so I can see what they do and how they do it for the next haulout.
