professionals are expensive and work in a high cost environment
This is 2009. The old idea of a moderately paid worker patiently completing a first class job is not really with us anymore. Expect professionals to come in, do a neat expensive job, get paid and get out.
I found that the only way that I could get work done on my boat
that I could afford was to do it myself.
I'd go along with the suggestion from Tom that you should get the boat cleaned up, motoring and sailing and try getting round the harbour. Use it for a while before you make any expensive decisions.
At this point I'd suggest putting in a small diesel
. Keep your eyes open for a good secondhand one of about 20hp. A new one has much to recommend it if your budget
Don't rip out the interior until you are sure what you'll put in its place. When you are put clear marks indicating levels and the positions where everything is to go before demolition. If you can use any of the existing interior as templates this will save time.
The carcass work, the internal framework upon which the interior is fixed, is two thirds of the interior work. Keep as much of it as you can.
Intentional Drifter is right about a good working environment
. Eventually you'll probably want to pull the boat from the water
, get the fibreglass to dry out, and properly do all the underwater part. Doing the exterior and the interior while the boat is on the hard
in a convenient location and with scaffolding will get you a superior, faster job.
