10 meter international precise measurment bow to transom

[easytiger]

This is my first post on the Trojan forum, I wanted to complement the owners of Trojan boats for being so helpful and willing to answer hard questions, I have a dilemma here, I've been sold on the 10 meter sedan for several years now but Alabama's Lake Martin has a law that has been enforced since 2008 called the 3 lakes law. In short, the law restricts boats being brought to our lake after 2008 to be under the length of 30'6". The boats that were here before the law went into effect are grandfathered in and are ok to stay. Knowing this you would think that I would stop pursuing the notion that i'm going to get lucky here. I understand that the LOA is 33' for the 10 meter, atleast that's what I have come up with online. The way that they are going to enforce the measurement is actually from the bottom of the transom with a plum to the front of the bow with a plum then measured in a straight line. Unfortunately there is a lack of Trojans here maybe a couple of tri cabins and there not for sale. You can bet if I wanted a searay at an inflated price then i'm in luck though. I currently have a newer Donzi medallion cruiser and though the construction is largely sound the Trojan would be more of a heirloom and a bit more revered . If you were in my shoes I believe the typical Trojan owner would sympathise and try to find a way to make it work too. Any thoughts short of find another place to go. Fingers crossed here.

I was hoping a 10 meter guy would respond . (Hint RWS) I think you will be out of luck on the size as I believe it is 33' . But hopefully a meter expert will respond .

Unfortunately it's going to over. A few of us took a tape measure to RWS's 10 meter last year. From end to end I think it was 39' and some change. That's including the pulpit and swim platform. Even just a hull measurement will be 33'.

here's the info we posted last year.

An interesting and fun day on the water was enjoyed by Forum members BOBCT and READY123 aboard RWS 10 Meter Express.

Before departing the dock a through inspection took place of all machinery and user upgrades and modifications.

After a luncheon of build your own sandwiches and snacks, gourmet fresh caught shrimp and multiple dipping sauces (hot sauce and pussy sauce) supplied by Ready123 the group posed for photos (to be added later) and then went about the tasks of evalusting the vessel and taking some notes.

For the record here are the actual LOA numbers on the 10 Meter Express Cruiser:

hull length - bow to transom rubrail 33' 6"

hull length including bow pulpit 37' 8"

hull length from bow pulpit to swim platform 39' 3"

waterline length (observed) 29' 1"

According to the hull speed calculation - <SNIP> 1.34 times the square root of the waterline length is just a rough approximation of potential hull speed. It is good only for fairly heavy (nowadays) displacement hulls. But actual speed potential for every hull will be slightly or not so slightly different, as there are several other factors involved.

Beam has been mentioned, but is actually meaningless of itself. Key factors are length, weight (displacement), and form (the hull shape). The shape of any particular hull's resistance curve will vary with any of these factors. Beam is only important as it generally follows that narrow hulls are lighter, thus resistance lower and potential hull speed higher. <SNIP>

The hull speed calculation for this vessel ciphered out at 7.2 knots per hour.

That said the real world application for our own testing purposes is actually 6.5 knots/hour on testing day with no allowance for tide or winds.

With BOBCT at the helm, our observed speeds:

low cruise 20knots 3000 RPM

nice most used cruise with engines feeling light and "singing" 22.7 knots at 3300 RPM

high cruise at max recommended cruise RPM 24.2 knots @ 3600 RPM

WOT speed was 27.1 knots at 4050 RPM

I sure appreciate everyone's replies. If I find a way to make it work out, then I will most definitely be a Trojan boat owner. I appreciate the time taken to respond. As frustrating as the local law is id rather ask the questions and be proficient then try and force my way along, after all maybe there's a reason we don't get what we want some times... Thanks again fellas!
