[Score: 5/10] 36" RETO Capable of 15mph and a runtime of 20mins Twin Propellors (2 Blade S Type 30mm) Direct Drive to a ??? (2 Blade S Type) Powered by NiCad (7.2v) 2Amp/h Batteries Controlled Through HOBBYYWING ESC - Comments: dumas commander wood is not the right type, having to change alot of things in the build, the instruction are not very clear at allllll. not like the other dumas boats. up to the hull finishing, have to bondo the hull cause of all the differences from one side to another, a pain and then have to fiberglass it, this is my first fiberglassing should be fun, if anything like my other boat, it is going to be a long process, takes the fun out of building the boat.
Hi Gents I have found this build fascinating including robbob's build. I have one these to build but will be doing an Aerokits Sea Commander first. As these designs go back to the 60's and were designed by Les Rowe ( I know I had one with an ED Racer in it.) So I will be referring back to this quite a bit. Will start a build blog on it. Shouldn't be to difficult busy changing my model engineering workshop to build boats. Model Engineering too expensive now boiler for my Springbok cost close GBP 1 300.00 alpne 😊😊. Trouble is I am importing all parts from UK etc. Between royal snail mail and SA post office I need to order any requirements in advance.
Hi All This year I bought an unstarted kit, but, sold it to a club member. A month later one of the club member wish to swap for a faster boat and as my Sea Commander required a repaint and fittings. I thought a swap for a very good working Hellen was a good deal. So are making a dingy and replacing the broken prop with a brass one I had my second Hellen for the year. Three weeks ago another Hellen pops up on Gumtree(aka EBAY), so it was to cheap not to buy it. While waiting for it to come, I made a new stand, a dingy with oars and a set of fenders. When it arrive the mast where laying on the deck broken, but , the posted pics show that. The motor is a 11 to 1 geared MFA Como 919 D which runs OK. A spare new plastic prop. Started on the repairs, like the keel and deck around the mast bases. The aft mast was broken in half, so I brass sleeved it. The aft sail was missing and the forward sail was all glued up, so I bin it. So this is the boat pics so far. Canabus
I have had this problem several times myself especially with fast electrics when they "flip" over. At present I take my old Aerokits Sea Commander with me to use as a rescue boat but there is always some element of difficulty when trying to line it up with the upturned craft. How you deal with it depends on the size of your boating lake. On small ones it is possible to have a vertical pole mounted on the bank with a long length of string attached to it. You then roll out the string and walk round until the string makes contact with your boat then slowly walk back bringing the boat to the side. Building a rescue craft like you describe is perfectly normal as I have seen them from time to time and also you see them on You Tube when retrieving usually (you guess it), a fast electric in distress. Good luck with your project and you can also disguise your "rescue boat" to look like a pusher tug etc.😁

I don’t currently have an operational boat so not at the moment. Back in the ‘60s I built a Sea Commander and used to sail that regularly at Princes Park. Eastbourne Model Power Boat Club use the lake but I haven’t seen them there for a long time, not sure when they sail, there are often EMYC events there though when I’ve been to the park, it’s a good lake.
I first started to build this boat with my father when I was about 15 . Then at about 45 I decided to compleat the build. It originally was built to have a Ed diesele engine,but was to costly to run so I changed to electric power. This proved to be the right decision. The boat runs wel, but when I turn on the full power it tends to lean to starboard and cavatat so I have learned not to put on full power. The sea Commander is a pleasure to drive.
Hi Morkullen I suggest a Hobbyking 3639-1100kv 35mm brushless motor with a 60 Amp ESC and a 2 blade 40mm prop. Battery a 3S Lipo 5800mah 25C will give you more than 1/2 hour. I had his setup in my 34" Sea commander with very good performance. Canabus
Get yourself a small pack of epoxy resin from ebay and seek out all slight delaminations of the plywood frames. Get the epoxy in those split bits and clamp them up. A clothes peg is sufficient if you're short of space. You can put a piece of cling film twixt peg and wood so the peg doesn't stick. Then use the rest of the epoxy to waterproof the insides. Be thorough and methodical. If you sand the model back to wood, use epoxy on that, either through fine model aircraft fibreglass cloth or just squeegee epoxy on all over with an old credit card. It goes much further and gets forced into the grain. It's not necessary to use GRP cloth on everything if it's well built. I have several over-50 year old model boats that are perfectly water tight with decent paint jobs (enamel, of course). Cheers, Martin
I think the three windows looks much better than the one big one. Wonder why it changed ? Cost - unlikely the difference can only be minimal. Though the bigger window at the front is likely cheaper than the three porthole in the Sea Queen. Does anyone know why the Commander has the 'spray deflector' (don't know proper name) on the front cabin, and the Queen does not ?
Someone mentioned ED motors! My Dad's old Sea Commander had one before I converted it to electric, but I still have it (in a box on the wardrobe!) Can anybody tell me anything about it? It is marked as an ED MK4 with what looks like a serial number of 4G147. It is water cooled and has a variable throttle. I cant see how the ignition worked but it has a large tug-start fly/pully wheel on the drive shaft. Any info gratefully received. Ian
Yes I've decided to sell most of my I.C. Boats and engine, because of this "nanny state" that we live in now. Probably 95% of clubs and sailing waters in my area(Liverpool) stipulate No I.C.s, l'm not traveling 50 miles to sail when in reality I've got several clubs and lakes within 5 to 10 miles from my home. I started model boat building in the 50s with balsa models and on to "aerokits" sea urchin, scout, rover, commander, and the holy grail the sea queen all of which had diesel or petrol engines. Granted we have come a long long way since then with electric and brushless motors, I do use them in both planes and boats, but there is still something to be said for the sound smell and reality of an I.C.engine in a boat, aircraft aren't to bad at the present, until they ban them to. Sorry for the rant but that's the way I feel.😭
Hi Laurence, check out the Build Blogs on this site. There are many covering various 'Seas', including my Sea Scout renovation with lots of tips re painting and varnishing. https://model-boats.com/builds/view/28209 Last pic shows the 'before' state after 20 odd years in the cellar! Have fun, cheers Doug 😎
