When is a dirty bottom hopeless

I am looking at s possible purchase of a 1978 Bombay 31 the pilothouse version. Boat has not moved in my marina since 2005. Has had a few renter liveaboards but owner has not used the boat for 9 years.

In those same 9 years the boat has not been cleaned nor bottom painted. In the southern waters (SC) that I am in you can imagine the result. Yes the growth is impressive some of it hanging down a full foot. My question is when is a bottom so had that it cannot be cleaned and restored? I see oysters at water line but am hoping the rest is sludge and barnacles. Does anyone here have experience or have heard of someone who went through the process of scrapping, cleaning, and painting of something this bad? Thanks. I will be calling a local diver this week to get his perspective and a quote...

Re: When is a dirty bottom hopeless

There is absolutely no way to determine the bottom condition without hauling her and stripping her bottom. There could be widespread saturated laminate, delamination or giant blisters under that oyster/barnacle farm.

If you think a dirty bottom slows you down ...... think what it does to your boat

The hysterical laughter you hear as you drive a way in your"new" boat ..... is the seller.

2) new bottom claening annd paint thru hulls etc. $2,400.00
3) New bimini's For captian and Crew $865.00
4) Auto plot repaire $350.00
5) New Diesel Fuel filter (FREE) Thanks John
I once said I got an almost free boat, Well I will not retract but I will admit it was a lot of work and cost some money. But I know my boat now from top to bottom all in the course of 18 months and it would have taken me years to learn a new boats systems. I think it was a good choice. Its a lot easer spending a little at a time and being able to sail at the same tome than the other way. I would never been able to swing that kind of money up front. I just wanted to say thank you to all of the guys on this site that helped me through the process It would have taken me a lot longer to complete this project without you. Again its not free.
On Saturday the forecast is high's around 75 degrees and light to med winds out of the north. So we sail.

Here are a few shots from when I found her rotting away on the mooring ball to today. Enjoy

Re: When is a dirty bottom hopeless

I owned a Bombay Clipper and loved that boat. I wouldn't be talking to a diver. I'd be hauling it out to attack the bottom and getting some much needed bottom paint on it so that you're right not back in this same situation in a few months. The bottom is solid glass. I wouldn't be afraid to go after it with a variety of power tools to clean the growth off. Good luck.

I had a few, as in less than 5 small blisters that where less than 1" diameter on my BC31. They are not known as hulls that have problems.

Re: When is a dirty bottom hopeless

Oh, the OP absolutely wants to talk to a diver, as well as the yard. If the bottom is as foul as he infers, a yard may need to charge him extra to barrel-up the excess growth and have it shipped off as hazardous waste, a very expensive proposition.

Re: When is a dirty bottom hopeless

Hazardous waste? Seaweed? Throw it back in to the sea. The sea is absolutely full of similar hazardous waste.

Re: When is a dirty bottom hopeless

Thanks folks. This is the kind of input I was looking for. I do wonder about the hazardous waste question. I am also worried about laminate penetration, delam or blisters. My research confirms as FarCry says that these hulls are solid glass and well built. My intent in working first with a diver is not to have the hull cleaned (necessarily) but rather to get his assessment of the situation. I have several experienced divers to choose from here. But prepurchase I do want a diver to give me his assessment.

If I get assurances that convince from a diver and move forward with the purchase, my next move would be to have pros do the bottom. A local yard actually is running a special on bottom jobs until end of February that involves free haul/return and first gallon of paint for a two coat ($19/ft) contract job. So my thought is a diver is my next step. I am thinking that if he finds lots of hard growth (versus sludge and barnacles) down under that I am looking at a deal breaker. Either way I will be very cautious to clarify this aspect of the boat before I get anywhere near a purchase decision.

Re: When is a dirty bottom hopeless

Seems pretty likely that any boat in a high fouling that hasn't been painted or cleaned in nine years is going to have significant hard growth fouling.

Re: When is a dirty bottom hopeless

I would be more concerned about the bulkheads sole and deck. If they are still solid talk the seller into letting you clean the hull. Then buy it, or buy it then clean the hull. I assume that it is cheap.
