How does one paint trailer cruiser hull and not leave lines

[2Sheets2Wind]

How does someone go about painting a trailer cruiser hull without leaving lines?

For example a 38 year old 19' O'Day Mariner. The boat weighs about 1300 lbs. According to what I have found on the web. The keel weighs 70 lbs. The mast and boom weigh about 50 lbs together. So if those items are removed, the remainder is about 1200 lbs or so. Can the boat just be rolled onto supports so that the deck and cabin are on the bottom? I would think that would be a terrible task to try to distribute more then a half ton of weight in such a manner so as to not crush the cabin.

Yet if you use some kind of support mechanism under the hull. Inevitably lines will be left where the paint stopped because of the support. With boats that spend most of their time in slips the areas missed because of jacks are no big deal because no
one sees them, since underwater. However trailer cruisers have hulls that are more visible.

This inquiring mind would appreciate some input. I've been puzzling over this question for the past several days.

Thank you.

Have a Great Day,

Paint what you can..let cure..jack up boat on keel line blocking boat only in already painted areas until you have enough room between hull and trailer to finish painting.

Dont forget to let boat back down before excited owner takes off for the water..

Paint what you can on the trailer.Make sure the trailer tires are blocked against rolling both forward and aft. Then lower the trailer tongue to the ground. Put blocking ,such as concrete blocks with a 2"x8" on top, under the stern at two points side by side. Now use the trailers tongue jack to raise the tongue to the jacks upper limit. Put blocking under the centerline of the boat up forward. Lower the trailer tongue until there is sufficient space between the bunks and the bottom of the hull. Once the paint is dry, reverse the process.
