help identifying inverted vee modified sea sled

[mackeralone1]

to start with hello to all fellow members.i am trying to get some information on a boat i just bought, i believe it is an american design any info on this boat would be greatly appreciated,or any info how to get some info would be good,i am at my wits end as all leads so far have been fruitless .cheers to you all,i have put some photos on but am really only a learner so please let me know if it was successfull

Welcome to the forum mackeralone. I see your photos in the gallery now.

Hell's bells, it looks like a "sea sled"......kinda. Obviously an unfinished project. I fear it will deliver a punishing ride, should you elect to finish it.

Yeah it's a modified sea sled, but who ever decided to change stuff, really needs to have known what they where doing on these puppies, or a really ill handling boat will result.

 

[mackeralone1]

yes I guesed it was a modified sea sled but cant find anything at all on it apparently there is one in America somewere being used .the person I bought it from has the plans but has mislaid them and is not willing to help with info don't know what the hatch on the pod is for or the horse power it will handle I guese trial and error will tell is it only a creek boat it has really got me intrigued

When working with an unconventional hull form, having the plans is paramount. It would be quite different with a regular V bottom of conventional proportions, but the sea sled is a different bird and subject to different issues. I'm pretty familiar with the sea sled, but you'll first need to know who did the plans and if they actually had a clue, about what they where working with. This is a hull form that's really easy to screw up, in terms of handling and trim. In fact, from what I see in the photos, it doesn't look like the person that did the plans attempted to adequately address the "tripping" issue, common with the early versions of this hull form.

 

[Mr Efficiency]

Well, if the person you got the boat from has "mislaid the plans" and isn't willing to help with any info, I'd be sceptical about it having identical sister vessel(s). Good to hear it is only going to be a creek boat, 'cos it would be best suited in flat conditions. As PAR is inferring, lay off any tight slalom turns, as the contents of the boat could get tipped out.

re sea sled

hello and thankyou both for your input into my problem, just to fill you in I as told the person that built the boat lives in Australia,he went to America on a holiday seen this exact same boathe got talking to the man who built it went for a ride in it and was so impressed asked for the plans came back to australiaand built it to were it is know unfortunately I bought it from a friend of his it was all done long distance, he was supposed to give me the plans but did not do so, so I can only summise there is none I think I have been had , its my own fault,i should have known better but I really like the concept the boat is 4.9metres long2.3 metres wide was told can take max 115 h/p outboard did see a seasled 17 wich is very similar but no pod.so I thought I would try this site and maybe get some answers so will just wait and just maybe someone will know something ,so cheers fellows any info is very much appreciated

 

[Mr Efficiency]

You can likely salvage a useable boat out of it, but as for being "had", that would depend on how much you paid.

 

[mackeralone1]

just a couple of grand so wasn't to bad do you have any suggestions have read the sea sled was a very good boat both for creeks and out at sea I am new to this boating industry

 

[Mr Efficiency]

My concerns would be around the seemingly very low platform at the stern, and how to ensure that ventilating the propellor with the aerated water generated and channelled by the underbody shape wasn't a problem. You'd hate to spend big money on an engine, only to find it can't maintain traction.

 

[mackeralone1]

I was thinking two 40s or 30 h/p going to try single 40 to start can you tell me more about tripping and what can be done

 

[PAR]

A 40 HP might be enough, though a 50 would be in the usual range for this type of boat.

It looks like some attempt to address tripping was done on the chine, though my experience suggests these flats aren't enough and as mentioned the deadrise aft is also in question. Without a known designer, you'd be taking a pretty good gamble with this puppy.

It's obvious she'll need a jack plate and possibly a "sneeze" guard too, but without a much better look at the hull, tough to tell. It looks like it has some aspects of the Mertens sled, but it would be nice to know for sure.
