Bow Sprit Attachment Questions

I have a Bowsprit designed into my sailplan for BooBooToo (an Ultra Pierre under construction). While I'm working on paint and engine and wiring ......, and getting ready for the upcomming initial launch, I am also trying to work out the rigging details and trying to project upcomming work in the sa...

Boarding Ladder Help

I am nearing launch time for my boat build (see some pic's under Ultra Pierre) and am beginning to turn my attention to misc. fittings and accessories. One item I need help with is a boarding ladder. I am looking for a design that will attach easily (likely to the combing on either side at midships)...

Re: Which Brakes?

Thanks for the feedback.

I'm still on the fence on this one. I guess it's like everything else in boating, comprimises abound.

Guess a little more homework is needed.

Which Brakes?

I'm close to finally floating my Ultra Pierre and have a question on brakes for my trailer. The donor trailer is a 1974 dual axle in great shape. Trouble is, in '74 they didn't have to have brakes on dual axle trailers (the laws have changed since then). The axles are 3500Lb each and the boat should...

Re: Shortening Evinrude Drive Shaft

Vettepilot, I appreciate the input. Nice to hear from someone who tackled a similar project, glad to hear the mod's you and your Dad made are still working. That takes a lot of the fear I had off in doing a similr modification. Let's see.... One Vote Machining, One Vote Welding...Hmmmmm. I checked w...

Re: Shortening Evinrude Drive Shaft

Thanks, that's what I was thinking too. I checked the shaft with a file last night, and it marked with little effort so I guess it isn't hardened. The reason for the post is I've had two different people over the years, tell me they have tried to do this operation before each had no luck. Frankly, I...

Shortening Evinrude Drive Shaft

My current project is an Ultra Pierre with some modifications. One of the modifications is in the outboard power. I am using a '55 (I think, maybe a '57) Evinrude 18HP twin for propulsion but to get it to fit in the location designed for it, I had to cut down the tower significantly. I have been abl...

Re: Outboard Engine Modifications

Upspirate, WOW, Thanks. There is a tremendous wealth of info here in the links you posted. The adapter in the web.mac.com link looks very similar in concept to the adapter I've designed. Perhaps I was over thinking the exhaust chamber design a bit too much and it's affect on performance. My motorcyc...

Re: Outboard Engine Modifications

pamelalynne1 Thanks for the feedback. I had not heard of surface piercing drives so I'll take a look this weekend. The max RPM due to mismatch of components doesn't have me too concerned (maybe because I don't know enough to be troubled by it yet). My thinking is that Hull speed is about 6 knots and...

Outboard Engine Modifications

I hope this is the right forum for this topic (it seems to fit the best). I am investigating modifying an outboard motor and before I spend too much time/money doing so wish to get some advise from the experts and devise a plan that has a better than good chance of success. My "doner" parts are from...

Re: canvas coverd coach roof

Doug,

Thanks for the advise (very welcome indeed). I have a small amount of canvas left from doing the deck so over the next day or so I'll try some mock-ups to try to get the technique down before I go on to the coach roof.

Regards,

Mike

Re: canvas coverd coach roof

Doug, Thanks for the suggestion. To be sure I understand: Leave the vertical corners of the top and the horizontal perimeter as shown square (roughly), lay the canvas to the top and beging stretching. when I get to a corner, cut a notch out of the canvas, secure the side and pull the remaining falp ...

canvas coverd coach roof

I am preparring to canvas cover the roof of my Ultra Pierre and am unsure how to best handle the corner treatments. For the deck, I pulled the canvas snug and overlapped the excess materials (hospitle corner fashon) and covered them over with the trim. The trim for the coach roof will be quite a bit...

Re: Ultra Pierre

I think all decisions in design have tradeoffs, and if your willing to live with them, then just about anything is possible (just mind the structural integrity). Yes you could move the well and reballast (that is what I have done). The "Ultra" gets narrow in the stern pretty fast so deck space and a...

Re: Ultra Pierre

beancounter, I think the original plans call for a full sitting headroom in the cabin. I don't have my mod's in front of me but if memory serves, mine'll be somewhere just over 5 feet (I think the original is slightly less but I have designed a steel bottom so am able to drop the deck and pick up so...
