I had…read morethe Side Mount shift lever changed a few years ago and ever since it just would not shift correctly. After several return trips to get it fixed without success, I had to give up on the repair shop that did the work. I then came across Curtis Boat Works and had a conversation with Don. He suggested a few things to look for that might solve the problem. His advice was right on target! It now shifts smoothly and as it should. I only wish I would have found Don sooner. Thanks again!

I took my boat to Sierra West in October 2024 to have SeaDek flooring put in it. Was told it was…read moreabout a 2-month job. 9 months later, multiple excuses, lied to several times and found out the flooring material was never ordered, extensive damage done to my boats hull and upholstery while it was in their possession, substandard work done (used superglue to fix a broken bow light when I asked them to install new one that I provided, put varnish/lacquer on my teak swim platform when I never contracted with them to do any work on the platform, built one of the floor hatch pieces incorrectly, etc. and I could go on). The final straw was when it was determined that his scanning equipment to accurately measure the boat for the SeaDek fabrication was broken and he was not going to be able to complete the flooring properly. His solution was to make a hand drawn pattern with mylar fabric and a sharpy!!!! The fabricator I spoke with said absolutely not and that he would not cut the SeaDek material with that type of method. I ended up taking my boat elsewhere to have the work completed. The hatch piece had to be completely rebuilt. I asked Sierra West for my money back and the owner refused. I took him to small claims court where he refused to negotiate in mediation prior to appearing in front of the judge. All I asked for was my money back which was $5000.00. Since he was unwilling, we had to go to the judge, so I sued for the maximum amount ($12,500.00) I won the case!!! He decided to appeal. We then went to the Superior Court, and he lied to the judge about the previous attempt to negotiate. He told the judge that I was the one unwilling. Ultimately, we negotiated finally and I got my money back. On August 24th, 2026 I received my $5000.00 back (almost 2 years later). I highly recommend you steer clear of this business. The poor quality of work, lack of respect and care of your boat while it is in their possession and lack of knowledge about the products to be used on boats (even though this is what they are supposed to be experts in) is scary. Don't let him do this to you.

I would give this place a negative five stars if I could. They wasted my time, money and took no…read moreresponsibility for their unprofessional conduct. I see there are a lot of people who have reported good experiences with this company, but that was not my experience. On August 20th, I emailed Kelvin at Delta Boat Works: "I am trying to schedule a date to bring my 42 Carver up for some repairs. Can you let me know if you have availability the first week of October, the last week of November or during December." Kelvin the manager responded: "That should be no problem, let me know a date and I will lock it into my schedule. Kelvin" I called him and spoke with Kelvin and explained I wanted an estimate on repairs and sent him an email with the list. I explained I was going away for a week and to contact me about the estimate so I could approve the repairs, and shared when I got back I need the boat as I am a live aboard. I called back in November to confirm bringing my boat up in November. No response. I had to call several times and was told it was "no problem". I navigated my boat from Pittsburg and took the day off of work to have enough time to review work I wanted done. I called ahead and they said they would meet me at the dock. It was a two hour navigation and I made good time. I arrived at 11:30A.M. and spent an hour speaking with Rick and going through the boat with him. Two things I specifically asked Rick to do was to connect the boat to shore power, since I had food in the fridge and make sure the boat was secure to keep vermin off the boat. He said "no problems and that he'd never seen any rats or racoons there before." I left for my trip and never heard back from anyone at Delta Boat Works. I attempted to call them and no response. I had a friend call them and he said they told them they would email me. Kelvin's response was that they couldn't get any estimates done because it was the holidays, but Rick would have one to me by the end of the day of Monday or Tuesday. Rick never did send me an estimate. I returned on the following Friday. When I got to my boat, it was a mess and in poor condition due to the storms that had been going on. I found the boat's aft cabin door had been left open. There was rat scat all over the aft deck. The boat was plugged in, but Rick never took the time to switch the boat over to shore power, so the food in the fridge had all gone bad. I emailed Kelvin and requested that Delta Boat Works compensate for the lost food and clean up the rat poop. I asked again for the estimate. I received no response from Kelvin, but a call back from Rick. He claimed that the crew told him that I had said the electricity was on in the boat when I left. It was a lie, because he was the last one I saw when I left. So, he took no responsibility. He also took no responsibility for the open door or the rats. I trapped and killed three of them on the boat before I got it out of there. I tried to salvage the appointment, but Rick brought up that the owner didn't want to work on a boat with someone who was a live aboard, at which point I said, "Forget it". I had explained the circumstances before I brought the boat up and was experiencing nothing but lame excuses and obviously no interest to work on my boat. So, I lost time and about $500 in fuel, food and traps. I would not recommend this place to anyone with a boat who values their investment. You may have a good experience, but you may not and who needs to waste time on a company that can't follow through? The good news is I am so glad they didn't start any work on my boat.

Plan B - find a boat yard to do a bottom job and several other projects on my 50 year old Coronado 27. While most kept saying that "yes they could do the work", none would or could come up with a date. Found Delta Boat Works by accident and stopped by to check them out. Not only were they very helpful, they were able to immediately give me a haul out date, only three weeks away. Just got the boat back today and was very happy with the results, everything was done as expected and at a reasonable rate. Rick and Jessica were very helpful, and followed up with progress reports and photos as the project progressed. Would I recommend them??? Definitly yes.
