magpie patrick Posted March 11, 2019 Report Share Posted March 11, 2019 Just a quick query, and a general question that I'm sure will get either one or two general answers or a host of variations! How high is a typical trailable cruiser when on it's trailer? I'm thinking a wilderness or a Viking 23? The reason I ask is a developer is proposing an arch over the access to a proposed slipway, and my suspicion is the proposed arch ain't high enough... Anyone any idea? I know it will be well over my head height, but that's not saying much! Link to comment Share on other sites More sharing options...
ditchcrawler Posted March 11, 2019 Report Share Posted March 11, 2019 I had a Wilderness and it had a good 6 foot headroom inside so probably 6' 6" to 6' 10" overall and it sat over half way up a 10" wheel and tyre so that is another 7 to 8" so it must be around 8' and that was with nothing on the roof at all like an aeril of chimney. @haggis could tell you what a Sea Otter is Link to comment Share on other sites More sharing options...
Grebe Posted March 11, 2019 Report Share Posted March 11, 2019 I used to be a Principal Technical Officer (best grade on BR) working in road transport, based on my distant work here goes: Grebe was a Sea Otter. Must be similar in height to a Wilderness or Viking. We measured the air draught at 5ft 7ins and the water draught at 1ft 6ins, so 7ft 1in of boat. Add 2ft 6ins for a big trailer and you're up to 9ft 7ins, say 3 metres. You then need to ad some wriggle room plus if ther is a slope involved a further allowance for the tapering.

rasputin Posted March 11, 2019 Report Share Posted March 11, 2019 2 ft 6 ins is high for the bed of a trailer. My wilderness will be under 8ft on the trailer Link to comment Share on other sites More sharing options...
haggis Posted March 11, 2019 Report Share Posted March 11, 2019 It is a long time since we had our Sea Otter on her trailer but I think it might be a bit more than 9 ft 7 ins. When I am standing on the ground when the boat is on the trailer, my head is well below gunwale level and I am 5 ft 3 ins tall. Add how much boat is above my head and I think it would come to a bit more than 4 ft 4 ins. I know this is not very technical but I would put the total height at over 10 feet. haggis Link to comment Share on other sites More sharing options...

Alan de Enfield Posted March 11, 2019 Report Share Posted March 11, 2019 It depends on the type of trailer - many 'boat moving companies' use Roller -Coater type trailers that will work with a variety of hulls but they do sit very high. It had two 'similar sized boats' and you can see one on a 'conventional trailer' and one on a 'roller-coaster' type trailer. The boat on the right has a slightly deeper hull but not much. I think there are too many variables and it is a piece-of-string question. Link to comment Share on other sites More sharing options...
bizzard Posted March 11, 2019 Report Share Posted March 11, 2019 Perhaps the boat could be tipped off just before the bar onto a bundle of broomsticks and rolled upon these down, ''ancient Egyptian method'' to the water, retrieve broomsticks afterwards as they float.

While you are at it, check the width, especially if there are any comers either side of the bridge 'ole. I've spent long periods manoeuvring when driving the tow vehicle straight through the hole results in the trailer catching (or vice versa) Link to comment Share on other sites More sharing options...
magpie patrick Posted March 11, 2019 Author Report Share Posted March 11, 2019 Thanks folks - very helpful - "three metres" was the sort of figure I had in mind the slipway will give access to a canal only suitable for narrow beam cruisers or narrow boats - as in draught and air draught limitations as well as beam - so the boats won't be that big Link to comment Share on other sites More sharing options...

Many trailerable boats are 'winched on dry' Its not a practice I'd recommend due the excessive loads on the winching eye, but it is very common on both the East and South Coasts. Run the boat up the beach - reverse trailer down to 'in front of the boat' - attach winch wire - winch boat onto trailer. 2 minutes ago, Naughty Cal said: Quite tall.

bizzard Posted March 12, 2019 Report Share Posted March 12, 2019 2 hours ago, Murflynn said: please advise method for retrieval of said vessel. Easy. just the reverse of launching it. Tow vehicle pulling it up on a long rope while someone keeps placing the broom handles under the boat. Bur!! Unless there's a crane handy the broomstick roller transport method might have to be adopted all the way home. But at least it got launched.

ditchcrawler Posted March 12, 2019 Report Share Posted March 12, 2019 When I was a kid we use to run the boats up the beach on rollers, the biggest problem the chap taking the one from the back and running round the front couldn't keep up and if you didnt watch it the boat would be in the sand.

Ancient Egyptians Phaerohs transported massive stone blocks on tree trunk rollers from boats on the Nile to build the Pyramids. Or of course a breakback trailor and wench.

The geometrical considerations of an arch make the whole thing thig more complicated. It's on the plan as a false arch - i.e it's actually a flat topped opening with a curve fascia - resolving tat would be easy, but of the top of the box is too low then it's not so easy...
